Mark and Raven are laying on his couch, no one is saying anything, its not an awkward silence, just silent.

"I probably need to go get Rachel."

"Why?"

"Addison is probably ready to kill me."

"You can't put that off?"

"No. Plus I need to find somewhere to stay."

"You can stay with me."

"You live in a hotel."

"So."

"Three people can't live in a hotel. It just won't work."

"Fine."

"Don't pout. It really doesn't work for you."

She gets up and walks to the door but turns around just before she opens it.

"Where exactly is Rachel?"

"Addison should be in her office. Fifth floor, when you get off the elevator go left and its at the end of the hallway."

"Thanks."

When she walks in Addison's office she finds Rachel asleep on the couch in Addison's office. Raven walks over to Addison's desk and leans against the wall next to her chair.

"You could've of told me you know. I'm your sister. I would have understood."

"Under the circumstances, I don't think you would."

"And what exactly are the circumstances?"

Raven sighs and starts fidgeting with her nails. A nervous habit she's had since she was a kid.

"I didn't mean for it to happen okay, he showed up at my apartment,…."

Flashback

"Derek? It's midnight."

"I know, I'm sorry, its just I had no where else to go, and.."

"You're rambling."

"Can I come in?"

"Yeah."

Derek sits down on the couch and Raven sits next to him.

"I caught Addison with Mark."

Tears start to form in Raven's eyes.

About that time the door to her apartment opens and Mark walks in. He sees Derek and knows right away that he told her.

"Ray, I'm so sorry.."

"Don't. I don't care that you're sorry. I don't care that it was an accident. I don't care. Get out. You can't get your shit tomorrow."

"Please, just let me explain."

"No. You slept with my sister. There's nothing to explain."

"Raven, you don't understand."

"Really. What don't I understand?"

He doesn't say anything.

"That's what I thought. Leave Mark. Please, just go."

Without another word he turns around and walks out the door. Tears are streaming down Raven's face. She sits down on the couch and basically falls into Derek's arms and starts sobbing.

"Shh, Shh. It's okay."

After a few minutes she calms down and sits back up.

"Sorry."

Derek just stares at her for a second and then starts kissing her, softly at first, but the kiss deepens quickly. He pulls her shirt off and starts fumbling with her bra clasp.

End flashback

"I didn't know I was pregnant until after he left."

"Why didn't you tell him?"

"I don't know. I planned on it. But you were trying to make your marriage work, and I don't know, it was just so complicated."

"When did Mark come into the picture?"

"After you left, I was scared and I needed someone to talk to. So I showed up at his apartment one day and told him everything. After that, it was easy to forgive him."

"So why are you here now?"

Tears start to form in Raven's eyes and she looks over at her sleeping daughter.

"She needs a bone marrow transplant."

"She has leukemia?"

"I'm not a match. Derek is my last resort."

"Have you talked to him?"

"Yeah. It didn't go so well. He wants to be a part of her life, but how do I tell her that the man she knows as daddy, isn't really daddy? How am I supposed to change everything she knows?"

"You don't really have a choice."

Rachel starts to stir on the couch, she sits up and looks at Raven.

"Mommy.."

"What baby?"

"Me not feel good."

Raven walks over to the couch and sits next to Rachel.

"What doesn't feel good?"

Rachel shrugs her shoulders

"You don't know."

She just shakes her head and then lays her head in Raven's lap. Raven puts her hand on her forehead, and then looks over at Addison.

"She's burning up."

Addison walks over and puts her hand on the little girl's forehead.

"You should probably take her to the pediatric floor and let them examine her."

Raven picks Rachel and walks to the door.

"Can you tell me where the pediatric floor is, and page Mark for me?"

"I'll just take you up there. I can get her seen right away."
