Desclaimer: I own nothing, but the plot bunny!

A/N: So new idea here guys... Based on Beyoncés song 'Best Thing I Never Had' because I am totally addicted to it and the entire album! Hope you enjoy!

We're doing things a little differently with this one...

-=-=-=-=-=-=-=- Best Thing I Never Had -=-=-=-=-=-=-=-

Penelope headed to the door, wrapping the silk dressing gown around her scantily clad body. She opened the door with a smile, yet felt the corners dip the moment she saw who was on the other side. She looked him up and down and saw her past coming back to wrap itself around her.

"Penny," Kevin started as he stood there, he looked her up and down and smiled. "Wow."

"Can I ask how you found me?" Penelope asked him, she hadn't seen him for nearly two years. "Actually, I don't think I want to know. Not today, not ever."

"Please, I was wrong. I never, ever, ever should've done that to you. I was wrong to take advantage of you like that," He then pushed Penelope into the room and then pushed the door shut behind him. "Please, Penelope. I love you."

Penelope scoffed a laugh, "You loved me so much that you jumped into bed with a stranger? Oh wait, she wasn't a stranger to you was she?" She asked him in disbelief, "See all of this, Kevin. The place you're at, the room you're in, the dress," She pointed to the wardrobe, "that's hanging up, this is what I wanted all along. A man that loves me with every ounce of his being." She then smiled as she thought at what today entailed, "I'm finally happy."

Kevin stood and felt like someone had pierced his heart. He was blind to ever think he could've just walked back into Penelope's life after so long without assuming that she had moved on. He now knew what karma felt like because looking at the smile on her face he knew she was entirely happy. However, a part of him wouldn't give up. He believed he wasn't too late yet.

"Penny, you know Morgan's type. He's a player. Once a player, always a player," He said trying to strike out at the thing that hurt the most.

Penelope saw read, "And once a cheat, always a cheat." She replied, her tone a stark contrast to the burning gaze she had on Kevin. "You do not know Derek, so how dare you walk in here and make those accusations like you're some saint." She then went towards him, "I will become Mrs Morgan by the time the day is out, and I will kiss my husband and in a couple of years time when I look at the family I have with him I will be sending you a thank you card for doing the dirty and letting me get the man I always loved."

Kevin stood shocked at that admittance.

"I'm sorry Kevin, but I dodged a bullet with you. I wasn't happy in Arizona and it took me walking away from it all to realise that. It took you doing that for me to realise what I deserve." She looked at him, "I can't thank you enough for blowing it or we would've been living in a state of denial and that wouldn't have had either of us happy." Penelope admitted, she had moved with him believing it would heal their relationship but really he had caused it to break even more and in the end Kevin sleeping around was a God send in its own way. On top of that, Penelope was finally able to release a lot of pent up anger and feelings after Kevin ran.

"There was a time I thought you couldn't do a thing wrong. That everything you did was perfect. Like you were some heaven sent saint and it took you sleeping with someone other than me to show me that you were nothing but an ignorant man like the rest of them."

"Like the rest of them?" He asked her and smirked, "and here you are marrying one."

"Derek's not like you," Penelope pointed out and saw the hurt strike across Kevin's face. "Nine years proved that to me. He isn't you Kevin."

"He will cheat on you though. Once a player, always a player it's true. That's what they say." He used that line again; he was clutching straws and losing his grip fast. He was out to hit hard and he knew if he could dampen Derek's reputation and name, he would weaken Penelope's hold on the idealistic view she had for Derek.

Penelope crossed her arms over her chest, "And to think I almost loved you at one point in my life. Boy was that a mistake." Penelope laughed and shook her head, "I like the real you Kevin. It shows I haven't really missed out at all." She told him truthfully, feeling like she now had her ground to tell him every ounce of emotion she had refused to let out in the early stages of their break up and ignorance for one another. "There was a time when I wanted you back. Thought I needed you back, but I didn't and it took me almost losing Derek to realise that."

"You know you don't mean that," Kevin almost sounded like a beggar when he said that and he knew if push came to shove he would drop to his knees if he thought it would get him anywhere.

"You're the best thing I never had, Kevin," She said with a smile, the apologetic tone remaining thickly in her voice. "I am so happy right now."

Kevin could fell his wits ends failing now. He wanted to shake Penelope, wake her up. Make her believe he was the better option for her, not Derek Morgan. Just hearing his name in his head churned his stomach. The agent had won over the geek again, just like the jocks used to.

"I think it's best you leave. The girls will be back in a moment and I need to be in that dress before they are," She told him and offered him a little smile, "I'm sorry it never worked out for us Kevin, but you had the cards in your hand and at the time I thought you had dealt me the worst hand possible." She then went opened the door, "I don't regret anything that happened. They're your regrets now."

Fleeing the room, Kevin took ever last piece of hurt and regret he had ever tainted life with at one point or another. He had no right to be there anymore, but he just couldn't leave entirely.

Kevin had hidden and waited and now watched down the aisle as Derek put his hand out for her to take, and just as the door shut on him, he couldn't mistake the smile and adoration displayed on Derek's face.

Foolishly he stuck around and followed them to the reception and hung around watching them. Praying that maybe there might be a moment that he could see that this was a deceitful event, that Derek was in one hundred and ten percent.

Every second he watched he couldn't deny it any longer. He had lost, well and truly lost and it was no one else's fault but his own and he had to accept it. Kevin sighed as he watched the first dance commence, he was trespassing now. He was gate crashing a wedding he had no right to be at.

"I bet it sucks to be you right now," Rossi said as he came back into the room, towards the blushing bride and the proud groom as they danced. He said nothing else, just the finishing pieces to Kevin's already made up mind.

Kevin couldn't lie. It did suck to be him.
