"Derek it's me." His sister tells him. "Look, it's been two months I've given you space but, you need to know the truth. Addison won't tell you but I will." Derek sighs.

"Nancy she cheated. I have no obligation to her anymore. I'm seeing someone." He insists looking around to be sure no one is listening.

"Derek Christopher Shepherd shut up and listen to me." She says in such a stern voice that he jumps.

"Nancy quiet down I don't need everyone to hear you." He warns her.

"Derek I didn't come here to fight okay?" She says softly. She looks down. "I came here to tell you what Mark did."

"What you mean the fact that he slept with my wife in my bed?" Derek demands as he rises.

"NO! I MEAN THE FACT THAT HE RAPED HER!" Nancy exclaims in anger as she too rises. Derek stops.

"What!?" He demands. His sister grows teary eyed.

"That's what she was trying to tell you Der. Mark...he...he...please don't make me say it again." Nancy cries. Derek looks at his sister for a split second and then realizes she's not lying.

"Oh my God. Oh My...I'm going to kill him!" Derek screeches heading for the door of his office.

"No! Derek stop, Addie needs you. You have to come to my hotel with me to see her." Nancy says grabbing her brother by his arm.

"She...She's in Seattle?" Derek asks in shock. "Damn it Nancy why didn't you say so! Let's go now!"be

Derek follows Nancy into the hotel room. He looks around but doesn't see Addison anywhere. He hears a noise from the bathroom but Nancy motions for him to stay.

"Addie?" She calls softly. "I'm back."

"I'm in here." Derek hears Addison call back.

"Addie can you come out here please?" Nancy asks her from the other side of the door. "I, I brought you something." Derek watches as the door opens and Addison exits slowly. He hardly recognizes her. She's lost a lot of weight, she's in sweats instead of her go to designer wardrobe, and she has no make up on. What had he done? How could he have abandoned her.

"Derek?" She squeaks in shock. "Nancy what...what is he doing here."

"I lied Addie, when I told you we were going to a conference I lied. But Addie he knows the truth now." Nancy explains softly. To Derek's surprise Addison begins to cry. Not just cry but sob. Addison Forbes Montgomery-Shepherd wasn't one to cry a lot. Derek instinctively moves towards her and pulls her into his strokes her hair as she breaks in his embrace.

"I'm sorry." He says as he too begins to cry. "I should've been there, I should have listened."

"I...I should h-have fo-fought harder." Addison chokes out. Derek holds her tighter.

"No Addie this isn't your fault." Derek assures her as tears stream down his face.

"He...he said you...you wouldn't b-believe me." She sobs into her husbands chest. Nancy watches, silently crying as well. "So...so I told Nancy."

"Oh Addison." Derek sighs. "I wish I could go back."

"Derek." She says with a deep breath pulling away slightly. "I know about Meredith."

"Listen Addison it was a mistake. I don't love her. I used her as revenge. Please forgive me. For everything." He pleads. "I love you so much and I promise we will get through this."

"I love you too." Addison says as she falls back into his arms. "But I have one condition. I can't go back to New York."

"We'll go anywhere you want." He tells her as he kisses the top of her head.

"Can we stay here? At least for now? I know it sounds weird but...but I need a fresh start and you have a job here."

"Meredith works at the hospital, I'll tell her everything but I just need to be sure you'll be okay with working with her." He asks. She looks up at him.

"I'll be okay, I just need you." She tells him.

"I'll be there every step of the way." He promises.
