Derek watched her walk away. He wasn't really sure what he wanted. He loved Meredith but he did have an obligation to Addison. He loved Addie too, but not in the same way. He was not the same person he was when he had fallen in love with her and neither was she. Maybe they were just kidding themselves thinking that they would be able to work things out. It had been almost a year since she had shown up in the hospital lobby, but still every time he looked at her he saw her in bed with Mark. There were some hurts that just wouldn't go away, it still hurt him to think about it and it always would. After all hurt hurts, he would have to tell her that it was over.

Finn watched her walk down the stairs. There was something in her voice that had worried him. Something had happened while she was gone...besides Izzie and Denny. He knew there was or had been something between her and Derek and he wanted to find out what it was. He looked at Derek, he looked sad and relieved at the same time. Maybe I should just go talk to him and find out what is between him and Meredith. I mean why was he calling her and why did she look so depressed and hurt?, Finn thought. Finn walked toward Derek. "Do have a minute there's something I wanted to ask you?"

Oh God, he knows. He knows that i just had passionate sex with his girlfriend. What do I say? I really don't need a confrontation in the middle of the hospital, Derek thought. He inspected Finn's face, he didn't look mad or suspicious. "Yeah, I have a minute" Derek replied trying to sound casual.

" I just ...wanted to know what was between you and Meredith..", he sighed, "and if it was still going on?" Finn asked not totally knowing if he wanted to know the real answer. Or if he should ask Meredith instead of Derek.

Derek turned his head away from Finn, took in a sharp breath, then turned back to him, "We have a past. I'm in love with her. And I will leaving my wife for her. I just hope she takes me back." He looked down at the floor, " If you want the details you should really get them from Meredith. Oh and Meredith doesn't know I'm leaving Addie so I would appreciate it if you didn't tell her". Derek started to walk away.

"Did something happen between the two of you tonight?" Finn called out to him.

Derek stopped walking and turned around to face Finn, "Like I said if you want details you should be talking to Meredith", Derek turned back around going in search of his wife. He knew he left Finn nervous, wondering about the possiblities of what had happened while Meredith and Derek had been gone that evening. He just wanted to go home and go to sleep. He would try to talk to Addison in the morning.
