Hi Guys and Happy Holidays.

So I recently discovered the GEM that is Beverly Hills 90210 thanks to Hulu and I've been obsessing over Brenda/Dylan coupling ever since. I have no idea what the writers were thinking with the whole Dylan & Kelly story line so I decided to write my own story.

This is going to take place during 3x27 A Night to Remember, but in my story the only thing that aligns with the episode was the pre-prom gathering thrown by Mr. Silver in the hotel room. After that my story line will take over.

I'm not sure if there are any Brenda Dylan fans out there in fan fiction land, but I felt this story needed to be told. Let me know what you think and if anyone is reading this I could be tempted to continue into a story.

Brenda sighed as she fiddled with the napkin on the table. She looked around at the room and wished she was having a better time. Donna and the prom committee had out done themselves with the decorations this year. The room seemed to have a special glow about it, the many balloons and streamers making the room seem almost magical. West Beverly had gone all out on a band and even got Kathy Dennis to perform. It was everything Brenda had ever wished prom to be, but here she found herself alone miserable at the table.

She had really tried to be upbeat about her date Tony Miller that evening. She put extra effort in her hair and make-up to try and compensate for her last minute dress choice. Brenda hoped she was giving off an un-bothered vibe that evening, but on the inside she was still broken up over Dylan. Regardless of her single relationship status, she found her-self having an okay time. She laughed at Steve's corny jokes and posed for pictures with the gang in the hotel room, even surprising herself by indulging in a glass of champagne or two.

She thought she was doing really well until she saw Dylan and Kelly dancing. The sudden rush of sadness caught her off guard. The smile she was trying desperately to keep up vanished from her face. For months she had tried to bury her feelings and move on like he had, but she just couldn't get over him.

He looked amazing in his tux, she noticed his hair was longer and a care free smile graced his face. She watched Dylan spin Kelly around and start to laugh. Brenda hadn't seen a smile like that on him in a while. She couldn't help but wonder if it was because of Kelly.

"Are you going to stare at them all night?" Tony asked her breaking her concentration. She looked up through her lashes at him, giving him a quick smile. She was about to apologize until he started to speak.

"I get it. Trying to move on can be a bitch." He admitted softly looking around the room. Brenda watched as Tony looked around until his eyes stopped on a girl in a yellow dress. She was a pretty blonde, Brenda recognized her from the cheer squad. The girl, Sarah, was surrounded by a couple of other cheerleaders, but looked to be dateless. Brenda racked her brain trying to remember any details about the couple.

The Beverly Hill gossip mill was reporting that the jock and the cheerleader split a couple weeks ago. Brenda didn't want to ask the specifics of the relationship, she knew first-hand how complicated things could get.

Brenda glanced back at Tony and realized he was looking at her. She smiled softly and held out her hand. Wordlessly she led him to the dance floor and wrapped herself up in his arms. The slow beat of Don't Dream its over was playing through the speakers; it was a perfect song for them to dance to.

Closing her eyes she leaned her head on Tony's shoulder. She tried to block out all the horrible things that had happened to her these past couple months and try to enjoy prom. This was one of her last high school moments besides the graduation ceremony. She wanted to make sure this dance with Tony was memorable.

While dancing she couldn't help but to compare the obvious differences between Dylan and Tony. Tony reminded her of the boys back home in Minnesota. With his broad shoulders and muscular arms Brenda felt comfortable in his arms. Even though being with Tony felt great, it was nothing compared to being held by Dylan. She missed the intensity of his hugs, Dylan used to hug her so tight sometimes she felt like she couldn't breathe. Brenda chastised herself and stopped before she got swept up in the past. This was supposed to be a Dylan free moment. She intentionally made sure she wouldn't have to see Dylan or Kelly while dancing with Tony.

Brenda's mom had reminded her of the magic of prom earlier while they were shopping. This moment she was having with Tony was just liked her mom described. Slowly Brenda pulled back and looked at him. She gave him her first real smile all night. "You know I never got to say thank you." She confessed to him, "I've had a really great time. I didn't think anyone was going to ask me."

"Please I wasn't going to sit back and let the prettiest girl in school not go to prom." Tony responded, joking with her. "I couldn't let that happen."

Brenda smiled looking down; she took a deep breath and fiddled with the flower on his suit coat. Tony was cute enough and was saying all the right things. But she couldn't get her mind off of Dylan.

Catching her by surprise Tony spun her around and dipped her little. He was a fantastic dancer. Brenda let out a laugh, "Who knew a jock could be such a good dancer? Any girl would be lucky to have you as a date."

Tony raised an eyebrow at her statement and started to speak, "I'm serious." She said cutting him off and shaking her head trying to snuff his doubts, "I'm confident a certain blonde would agree with me."

Brenda gestured her chin in the direction of the girl from earlier. She was watching them dance while her friends gossiped in the background. Brenda recognized the forlorn look on her face; it was one she wore well. Sarah looked away when she noticed Tony and his date starring at her trying to give off the impression she wasn't starring.

"Why don't you ask her to dance?" Brenda offered suddenly as the song they were dancing to came to an end. Brenda recognized the new tune playing it, was a popular song at the moment. The melody reminded her of the drives she and Dylan used to take along the coast.

Tony looked over at Sarah in her yellow dress and his heart jumped into his throat why would this song be playing. 'Their song' the little voice in his head reminded him. He glanced over at Brenda and stared at her. This was senior prom he didn't want to ditch her in the middle of it.

"I don't know… I couldn't. Plus I don't want you to sit out. It's your prom too." He said looking at her, but his gaze quickly went back to Sarah.

"To be honest Tony, I think I'm all promed out. I'll just grab a taxi and head on home." She confessed leaning up and kissing his cheek in goodbye. "Thanks for an amazing night."

"But it's early." He exclaimed looking at his watching, trying to stop her. "One more dance."

"My night couldn't get better than it already has. I might as well bow out on a high." She confessed.

Tony caught her hand giving her one last look, making sure she's okay. Brenda smiled softly and squeezed his hand. "I'm fine really. I'll see you in school." She said softly.

Tony watched shocked as she made her way through the crowd. He kept his eyes on her until she started to gather up her purse and other belongings. Brenda Walsh was really one in a million.

Brenda grabbed her purse off the chair and picked up the crumbled napkin from earlier and threw it in. She turned around just in time to see Tony leading Sarah out to the middle of the floor and start to dance. They made eye contact once more and they both smiled. Brenda waved as he mouthed thank you in her direction.

It made her feel good that at least one of them would be able to have a moment with someone they loved at prom. Brenda turned in the direction of the exit and started walking towards the door. She didn't see Brandon or her friends anywhere. She finally spotted everyone by the stage talking and laughing. Her chest gave a twinge of sadness when she realized she was left out again.

Ever since that day in the park things had changed for Brenda. She was more reserved and less trusting with everyone. In return it seemed like all of her friends had formed these secrets recently and she wasn't included. No one had intentionally chosen sides, but the lines were drawn.

Brenda hadn't even noticed the tears slip from her eyes and down her cheek. Her hands reached out to brush the marks away before anyone could see. Quickly, she made her way towards the doors of the ballroom. As she reached the door, Brenda turned and took one last look around the room. 'Senior Prom', she thought looking around trying to be excited, but couldn't muster up any joy. She knew this night couldn't even hold a candle to the spring dance.

Brenda pushed through the doors and made her way to the lobby. Her heels made a clicking sound over the tile floor. She could still hear the music bumping from the ballroom. Reaching out she gripped the banister as she made her way down the steps to the exit, thinking about the spring dance again.

"Best night of my life." She said softly, starting to cry. Brenda remembered that night like it was yesterday. The combination of her dress, the hotel, the music, the evening was perfect. Not to mention finally sleeping with Dylan. Getting lost in the memory, Brenda didn't hear the ping of the elevator doors opening to the lobby.

From inside the elevator, Dylan saw the flash of her dress as Brenda sped by. She was walking so fast he barely made out the tear marks on her face. "Brenda." He called, stepping out of the elevator and towards her.

Quickening her pace, Brenda ignored him and kept walking to the doors. Maybe he'd get the hint and leave her alone like he left her.

Dylan frowned momentarily at her brush off and rushed after her. He knew Brenda could hear him calling her name. There were only a few other patrons in the otherwise deserted lobby that evening. It was a little after nine and prom was just getting started, but Dylan was ready to leave the minute the gang walked into that ball room.

Being surrounded by people he really didn't like listening to some singer he didn't even know was not how Dylan wanted to spend his time. The combination of alcohol being served earlier and Brenda walking in on the arm of Tony Miller instantly ruined any good mood he was going to have. He knew it was wrong for him to be jealous, but his stomach churned at the thought of Brenda with another guy.

Even though he was with Kelly, Brenda was constantly plaguing his thoughts. After that day in the park he hardly saw her anymore and it drove him crazy. He didn't expect to miss her as much as he did. It was like a Brenda shaped hole was missing from his life. Sure they talked and she opened her home back up to him when his dad died, but it wasn't like before.

"Brenda." He called again. Dylan sped to catch up with her rapid pace and reached out to halt her by grabbing her on the arm.

"Wait a second." He said finally stopping her. Brenda immediately broke out of his hold and stepped off to the side. She tried to discreetly wipe her tears, hoping he didn't realize she was crying. Brenda refused to make eye contact, choosing to look at the floor and out the lobby doors.

A few weeks ago he could look into her eyes and know exactly what she was feeling, but standing next to her here, he hadn't a single clue. A part of him knew she was avoiding him, intentionally changing her routine so she didn't have to see him lingering around the halls. He complied keeping his distance, Dylan didn't want to cause her more pain.

"Did something happen?" he questioned glancing back towards the doors at the prom and back at her. "Did Miller do something to you?" he asked growing angry.

Brenda glanced up at the mention of Tony's name, 'No." she admitted softly, finally making eye contact. She was instantly swept up in his rich brown eyes. "It's not him. It's nothing really, I'm just being silly."

"It's not just nothing, Bren." He said in the same tone she used, "You don't just cry over nothing."

Brenda took a deep breath before answering him. It was getting harder to hold up this facade of happiness. When they first broke up, Brenda promised herself he would never see her cry over him. The breakup was her idea and she had to live with the repercussions of her actions. She was upset that she had broken her rule of 'no tears' in front of Dylan, which was making her more upset. Her throat was tightening rapidly and she could barely blink away the tears that were pooling in her eyes.

"Look it's not a big deal. I should let you get back to the dance." Brenda responded trying to smile. She prayed it didn't look too shaky and that Dylan didn't pick up on her voice trembling. She just couldn't catch a break tonight. All she wanted to do was go home, take off her heels, and drown her sorrows in a bowl of rocky road. Brenda walked away from him turning back around once more as reached the doors. "If you see Brandon can you tell him I went home early?" Without another word Brenda pushed open the doors and walked through them.

"Wait, where are you going?" He said surprising himself by pushing open the door and chasing after her. Dylan watched her walk to the curb and signal for a taxi. He took the opportunity to look at her without interruptions or judgment. It had been a while since he had been able to do so.

He was always captivated by her legs from the first moment he saw her. Tonight they were on display in her short silver dress and shiny shoes to match. Her hair surrounded her face like a halo which made a stark contrast between her white skin and dark hair. He frowned noticing she looked thinner, her jawline was more pronounced and cheekbones stuck out making her seem older than eighteen. Even with the little changes she was still the most beautiful girl he'd ever seen.

When she broke up with him he was crushed. His pride would let him grovel and beg for her to take him back like he did before. On the outside he made it seem like he was unaffected by the split, quickly finding a new girlfriend. But on the inside he was still in love with Brenda. There were times he was with Kelly and the only thing on his mind was Brenda. Dylan knew it was wrong to think of his ex-girlfriend so often, but he couldn't help it. He ran a hand through his hair and stood next to her on the street corner.

"I was about to head out myself." He said. "Can I give you a ride?"

"I don't think that's a good idea." She said in a rush, "I'll just catch a cab…if one would stop." She waved her hand out again as another taxi whizzed past her. Stomping her foot Brenda let out a sigh in annoyance.

She knew the fastest way home would be the ride with him. She watched Dylan fish the keys out of his pocket and spun them on his finger. He raised his eyebrows up at her expectantly awaiting a response.

Brenda considered her options quickly as the cool night wind started to blow around them. She wished she would have grabbed a wrap or something to cover up with. Catching a cab was taking longer than she anticipated and it was starting to get unusually cold for L.A. She didn't look at Dylan as she started walking towards his car, making her decision. She could hear the crunch of gravel as Dylan walked behind her.

She hated that she had to accept help from Dylan, but she did want to get out of there as fast as possible. After he unlocked the doors she plopped down onto the passenger's seat and after a few seconds the car roared to life. Brenda reached down and started pulling at the straps of her shoes. There were thick red indents from the plastic digging into her ankles.

"Price of beauty huh?" Dylan said motioning to her shoes trying to make a joke as he turned onto the busy street, but was met with silence.

Brenda glanced over at him for a moment before blankly starring ahead refusing to give him the satisfaction of engaging in conversation. 'He's just my ride.' She thought as she looked out the window. Her goal was to ignore him the whole ride home. The buildings started to blur together as they sped down the road. Luckily, it was a short ride back to her house from the hotel and with Dylan's driving she'd be home in less than ten minutes.

"Do you want to talk about it?" Dylan asked looking over at her, then back at the road. Brenda said nothing as she continued to stare out the window. The tension that filled the car was thick it made his head spin. He sighed and started to mess with the radio. Landing on a station, Dylan tapped the beat along the wheel trying to fill the car with some kind of sound. He was grateful for the murmur of the radio to make up for the silence.

Shaking his head Dylan continued to drive pressing his foot down harder on the gas making them go faster. Before he knew it Dylan turned onto the familiar street and pulled up to the Walsh's house. Brenda clicked off her seat belt and stared ahead. She was afraid to speak or say how she really felt in fear of bursting into tears.

"It looks dark in there." He said breaking the silence, not ready for her to leave.

"My parents aren't home." She whispered back, finally speaking, "My dad surprised my mom with a weekend getaway. So it's just me."

The heavy silence returned to the car. They both didn't say anything as they continued to look at the house. Brenda squirmed in her seat and reached for her shoes. She grabbed her shoes and bag before turning to face him, "Thanks for the ride. I'll see you around or something." She said dejectedly as she reached for the handle with her free hand to open the door.

"That's it?" Dylan exclaimed loudly making her a jump in surprise. She let her hand fall from the handle and stared at him.

"Thanks for the ride? I'll see you around?" He repeated, "This is me you are talking to Brenda, remember that. I know you better than anyone and this whole silent treatment routine isn't going to work on me. I know I'm the last person who should be asking anything of you, but just talk to me. I mean find you crying tonight and you won't even tell me why. I thought we were closer than that. I thought we were friends."

"Friends." she said bitterly, the word foreign on her lips. "I wouldn't call us friends."

Dylan looked down in surprise not expecting her harsh response. "I thought that after everything that happened with my Dad and then Kelly getting hospitalized, all of us were finally getting to be in a good place." he trailed off.

"Well I guess you thought wrong." She spat interrupting him. She went to open the door and frowned when she found it locked, "Look just open the door so I can go inside."

"No." Dylan answered irritably, turning off the car and focusing his attention on her. He was trying to keep his emotions under control, but that was a hard thing to do around Brenda. "I'm not letting you out until you tell me why you were so upset earlier."

"I'm not your girlfriend anymore, why do you even care?" she countered angrily. Brenda let her head rest against the back of seat. Since the breakup had kept her true feelings about him under wraps and they were bursting at the seams desperate to be acknowledged and released.

Dylan was stunned at the raw emotion flickering through her face. He watched her take a couple of deep breaths trying to calm down. He knew the signs of Brenda Walsh melt down, the wild eyes and flushed cheeks were a dead giveaway. Dylan knew she was on the verge of cracking, if he pried a little harder he was confident she would tell him what was bothering her.

He reached out slowly and slid his hand on top of hers and he gave it a gentle squeeze trying to be comforting. She didn't hold his hand in return, but she also didn't push it away. "What's going on Brenda?"

Brenda looked down at his hand on top of hers. If he wanted to open this can of worms she was going to let him have it.

"I was crying because." She started as her voice started to crack, "I was crying because I'm miserable Dylan." All of the feelings Brenda had been holding back were finally spilling out and down her cheeks. Before she knew it she was bawling in front of him, "I wake up every day and it feels like I'm drowning. Like there are rocks in my pockets weighing me down and I can't break the surface for air." She gasped out, "And I try and I try to be mature and be the bigger person but I just can't do it anymore."

Dylan felt his jaw drop in surprise. They had dated for three years and he only saw Brenda this upset a handful of times. Dylan continued to stare at her in shock as she sobbed openly in her seat. He noticed over the last few weeks something different about Brenda and he couldn't put his finger on it. She still sat with the gang at lunch and hung out with everyone at the pit, but something was different about her. Dylan had no clue he was the reason why. She didn't give off any indication that she was wrecked over him.

"You just forgot me." She cried, sobbing harder, "You chose her and never looked back. Not even once to see if I was okay. Do you know how bad that stung?"

"I could never forget about you." Dylan said trying to interrupt her, but Brenda talked over him.

"I gave you every part of me Dylan. Everything I could have possibly given you I did, and how do you repay me? You sleep with my best friend and lie to me about it for months." Brenda choked out. Overwhelmed, she turned towards the window and covered her eyes with her free hand.

Dylan didn't know what to say. He was frozen in his seat unable to move. "I told you I didn't sleep with her." He said quietly unsure if she could hear him over her sobs. "I wouldn't do that, not to you."

Brenda scoffed loudly and pushed his hand off hers, "Well excuse me if I don't believe anything you say." Brenda snapped. "Open the door Dylan I want to leave."

"No." he answered defiantly, grabbing her hands back preventing her from moving. "I'm not done with this conversation and neither are you."

Dylan couldn't let her leave, not in the middle of this. They were finally talking. Well it was hear screaming and yelling at him, but at least she was speaking to him. He would take whatever he could get.

"I hate you." she cried unexpectedly catching him off guard. Dylan winced and closed his eyes at her words, still keeping a firm grasp on her hands. "You broke me. You broke my heart and I hate you" She yelled out pushing her hands against his chest trying to break free, "and the worst part is I still love you and I hate myself even more for it. Are you happy now Dylan? Is this what you wanted to talk about? Just let me go!"

"I can't." He exploded opening his eyes and looking at her. Brenda was stunned to see the tears reflecting in his eyes, "I won't Bren. Not until you know how sorry I am and that I never want you feel this way."

She tried to resist, but was powerless as he grasped her shoulders pulled her closer. He cupped her face and wiped her tears away with his thumbs. Neither of them said anything, as Dylan continued.

"I told you a long time ago I didn't want to make you feel bad. I don't want to be the cause of your pain and it hurts me to know I'm making you feel this bad. Even if we aren't together doesn't mean I don't still care about you. Those feelings just don't disappear overnight, Bren. I know I've made it hard for you to trust me, but you have to believe that."

Dylan continued to wipe her tears trying to hold back a few of his own. He felt like the lowest of the low.

"You just seem so happy." She confessed after a few moments of silence, "All I ever wanted was for you to be happy and it breaks my heart that I couldn't do it."

"You did make me happy. You don't know how much." he said passionately trying to make her understand. The time he spent dating Brenda was the highlight of his high school experience he could argue it was one of the highlights to his life so far.

"Then why did you choose her and not me?" Brenda finally asked. The question had been weighing heavily on her mind since the start of their conversation.

Dylan blinked back in response. He couldn't tell her the real reason behind his decision making. How could he tell Brenda the truth? He sounded like an asshole when he said it aloud. Kelly was there that night for his father's party and Brenda wasn't, simple as that.

Brenda held his stare and leaned forward. For a moment Dylan thought she was going to kiss him. He felt his heart speed up in the familiar rhythm and her perfume assaulted his senses. Taking advantage of his state, she slipped by him and unlocked the door. Quickly she lifted herself out of the car and turned to face him. "You know what…I don't want to know. It still doesn't change anything between us. Thanks for the ride."

Dylan watched helplessly as she almost ran to her front door. Before his mind could catch up with his heart Dylan found himself following Brenda for the third time that evening. He barely caught the door with his hand before she shut it.

"Dylan." Brenda said frustrated from behind the door. Why wouldn't he just leave her alone?

"You keep running away before I get a chance to finish what I have to say." Dylan said squeezing his way into the house. He shot her a look as he looked down at her trying to control his breathing. He sprinted to catch the door.

Brenda dropped her heels on the floor and made her way over to the stairs. She wanted to get out of this dress as soon as possible. Lifting her hand she rubbed her temple trying to relieve some of the building tension.

"What's left to say that you haven't already said? You care for me, but not enough to be with me. Is that what you want to say? I received that message loud and clear Dylan." Brenda couldn't help but be bitter, she was heartbroken after all.

Dylan looked over at her sharply. He thrust his hands in his pockets trying to build up his nerve. He had been debating on saying this to her for a while now. He thought his chances with her were long gone, but she confessed she still loved him earlier and his heart skipped a few beats at the idea of reconciliation. Unsure if he would get the chance again, Dylan decided to tell her. He took a deep breath, "What if I said I made a mistake? What if I told you I still love you and never stopped loving you? Would that change things?"

Brenda's heart stopped beating in her chest and she froze. She dropped the hand that covered her face and looked at him in shock. She had waited for weeks to hear those words from Dylan. Paralyzed Brenda watched as he walked towards her meeting her at the bottom of the steps. He leaned his tall frame against hers, trapping her against the railing. She chewed on her lip as he continued to speak.

"What if I said I was sorry? That I am deeply and truly sorry for ever causing you any pain. And if you'd even consider taking me back and give us another shot, I would never leave your side again." Dylan said starting to break down, "I was too scared to tell you I was having doubts and I was feeling insecure about our relationship. So in turn I…I pushed you away to try and protect myself. Like when I pressured you to go to Paris along with your parents. I know I can't change the past and the hurt I've caused you, but I've realized my mistakes and I want to make things right. I'm here asking you for one more chance...I'm asking you to give us one more chance."

Brenda didn't say anything, as she tried to process the hundreds of thoughts racing through her mind. She knew what it was like to make a decision and instantly regret it. Brenda felt that way about their break up all the time. Brenda licked her lips and thought about what Dylan just said. She never expected him to be here confessing his feelings to her. She was sure he was still involved with Kelly and if she acted on her impulses she wouldn't be any better than her ex-best friend.

Dylan sighed at her lack of response, instantly feeling stupid for getting his hopes up, "I guess it's too late then?" Dylan turned and started to walk towards the front door. He could feel the tears building in his eyes.

"Wait.' he heard her say as his hand reached the knob. Dylan turned around just in time to catch her as she launched herself into his arms.

Before either of them could say anything Dylan pressed his lips to hers. They sighed as the familiar fireworks went off in their stomachs as they kissed. He gripped her back trying to pull her closer to him. Frustrated at the angel, he hoisted her up letting her legs wrap around his waist, never breaking the kiss. His back hit the door as she pushed herself up against him trying to get as close as possible.

She moaned and slipped her tongue into his mouth, they made out there in the foyer for a while not worrying about of the time, just happy to be in each others arms. Slowly Brenda broke the kiss still keeping her eyes shut, she felt Dylan move to trail kisses down her neck. He refused to put her down still keeping her wrapped around his waist against the door.

Brenda yanked the curls at the back at the back of his neck softly trying to get his attention. "Take me upstairs." She whispered into his ear and shot him a shy smile. Dylan could only nod as she moved back in to kiss him. He kept one arm firmly around her waist and used the other to grip the back of her head, deepening the kiss.

Brenda unlocked her legs from his waist and slid down his body. Her feet barely hit the floor before she was whisked up the steps by Dylan. He took the steps two at a time not wanting to give her the chance to change her mind.

As they climbed the steps, Brenda started to think about what they were about to do. Brenda knew deep down this may be a bad idea. She watched him open her bedroom door and pull her in. They both didn't speak as he pulled his tuxedo jacket off and lock her door.

He rested against it for a moment before he moved to wrap his arms around her and squeeze her tight. He smiled softly when she didn't resist. Dylan just held her for a moment trying to make up for lost time. Brenda was torn, a part of her was screaming that this was wrong, but another part was crumbling into Dylan's embrace.

"Don't over think it." He whispered to her while kissing her head. Brenda looked up and flashed him a radiant smile. It was just like Dylan to know what she was thinking before she said it. She moved in to kiss him again, pushing all thoughts of doubt from her mind.

This was her Dylan, she loved him and she knew now that he still loved her. She felt his hands move to the top of her dress and start to pull down her zipper, letting the dress pool around her ankles. Still kissing Dylan moved Brenda towards her bed. Who could blame her for not resisting… it was prom night after all.
