This is based off of the last episode. I'm hoping that what Mark said means that they might get back together. So this is a possible story.

I don't own anything.

Lexie Grey sat on top of the closed toilet seat in Meredith's bathroom.

It had been a week since she and Mark had broken up. Derek said that he was coming back to Seattle, but he was going to take a vacation there with Sloan after she was better because she had been so stressed out.

Izzie had come back the day after Mark left. She and Alex were working things out. Lexie was happy for him. There had never been a relationship for them. They were both hurt and just needed sex.

The day's events were a blur.

She had completely skipped. She took several tests and they all came back positive. Her mind had immediately gone to December when she also skipped. She had chalked it up to stress because Sloan had been living with them and was terrible.

She had blackmailed a married OB, who had slept with Mark a couple a years ago and had been married at the time, into running her labs secretly.

Her suspicions had been confirmed. The rest of the day had been a blur of patients and noise.

She had gotten home before anyone else. She now sat in the bathroom with the door pretty much closed. She had the phone in her hands. She knew she had to call him. She took a deep breath and dialed the number that she knew by heart.

"Hello?" Lexie instantly recognized Sloan's voice. Why did she have Mark's cell anyway?

"Hello?" Sloan asked again. Lexie hit the call end button and threw the phone into the bathtub where it broke and made a loud noise.

She didn't know Meredith and Derek were home. But seconds later they came into the bathroom.

"Lexie, what going on? Are you okay? We heard a crash." She said as they walked into the room.

Lexie simply shook her head and felt the tears start to fall. She handed Meredith the folded lab workup.

Meredith looked at it and came to sit on the edge of the bathtub beside her.

"Oh, Lexie." She said, gently stroking her sister's hair.

Derek picked it up from where Meredith had put it on the counter.

"Oh." He said looking at it.

"Hey, Derek? You think you could maybe go downstairs for a little bit?" Meredith asked, looking at him.

"Oh, yeah, sure." Derek said. He admitted he felt really confused and awkward. This was his best friend's ex-girlfriend, who was also his wife's sister. He started to worry that he would have to take sides. And the truth was he didn't know who he sided with.

After Derek left the room, Meredith turned to Lexie and said, "What are you going to do?"

"Well," she said as she ran her hands through her hair, "I'm gonna call Mark."

"Wait," Meredith said, "You're way too stressed out. First, you're gonna take a hot bath. Then, you're gonna eat ice cream and watch a random movie. Then, you can call Mark."

"But, Mer…"

"No arguing Lexie. This is the patented Grey stress relief technique. Now go. I'll even clean the tub for you."

"Hey, Mer," Lexie said as she stood up.

"Hmmm?" Meredith asked as she got the cleaning supplies out of the cabinets under the sink.

"Thanks." Meredith put the can of Scrubbing Bubbles on top of the counter.

"You're my sister Lexie. It's what sisters do for each other." Meredith said pulling Lexie into a hug.

…………….

A about two hours later, Meredith made her way up to her sister's room. She gently knocked on the door and when she didn't get an answer she carefully opened the door.

Lexie was asleep; an empty carton of ice cream was on the bedside table beside her. The end scene of the movie Fame was still playing on the TV.

She carefully walked over to get the ice cream. As she moved the carton, she noticed a note under it and immediately recognized Lexie's neat yet girly writing.

Mer,

I'm really tired and will probably fall asleep. I tried to think of ways to tell Mark, but I can't. He chose Sloan over me; I can't bear to talk to him. I still love him, but I don't think he still loves me or if he will ever love this baby. Could you get Derek to call him?

Love you and thanks for being there,

Lexie

Meredith gently brushed her sister's hair away from her face and pulled the blankets up around her.

She then went downstairs and showed Derek the note who had quickly agreed to call Mark.

……………

Mark Sloan sat on the couch in the hotel room. He hadn't slept in a week. He couldn't bear the thought of waking up and not having Lexie in his arms. That night with Addison was the first time that he had admitted out loud that he still loved Lexie.

He was going to go back to Seattle and somehow find a way to be with both of them.

He was thinking of ways to do this when his phone rang,

He glanced at the caller ID. Derek.

After talking to Derek he went into Sloan's adjoining hotel room and sat on the edge of her bed and gently shook her awake.

"Dude, it's like midnight." She said looking at him with a very unimpressed expression on her face.

"Don't dude me." He said smiling.

"Seriously though. What's wrong?" She asked sitting up.

"I have to go back to Seattle a bit early."

"Oh, okay." She said.

"You can stay a bit longer if you want." He said looking at her.

"You know what? I think I will. Why do you have to go back to Seattle?"

"Well, you see, Lexie…"

"Mark, I know you still love her. I know that you chose me over her. I could hear you. I don't want you to throw your relationship away over me."

"Sloan, you're my daughter. Lexie was my girlfriend. I made a choice."

"You're not happy though. You're my dad; I want you to be happy."

He hugged her and then walked out of the room to go pack. He was leaving on the earliest last minute flight he could book, which was 8:30 A.M.
