A/N: A short, but eventful update. I'm having a problem…After Thursday's episode, I don't know who I'm shipping for anymore. I almost feel bad for Mark cuz she's using him, and I think Addex would be really hot, but the MAddison scene at the end was too hot to ignore. It's pretty much been determined that Lexie will hook up again since they're going to be the Ross and Rachel of Grey's, but I still want to see some Addex action first. But as for my story, I really don't know, so we'll see where the story takes me.

They got back to her hotel and took the elevator up to the 22nd floor. Addison subconsciously let her gaze linger on Mark's hotel room door before she snapped out of it and swiped her keycard to enter her own room. "Are you sure you're okay?" Alex asked as he followed her inside.

She looked up at him and saw the reassurance in his eyes. She smiled and walked over to him and looped her arms around his neck. "Yes, I'm fine," she said before she softly kissed him. When they broke their embrace she looked back at him, noticing for the first time his resemblance to a younger Mark, both in appearance and personality. Everyone knew that Alex had slept with Olivia while he was dating Izzie, and she had heard a rumor that he slept with some cancer patient in the bathroom at Joe's. Why would she be any different than Izzie? Everyone saw the way Alex and Izzie looked at each other—they were in love, not unlike herself and Mark used to be—but Alex had slept with someone else. Had he really matured that much in the last few months that he wouldn't do it again?

"What?" Alex asked, sensing something was off, her arms still around his neck but breaking her from her trance.

"Nothing." She kissed him again to reassure him that everything was okay, and hoping it would comfort her. "You know what? I have an early surgery tomorrow, and I need to check on another patient before that. It's late so I should probably get to sleep."

Alex looked at her, somewhat defeated, but nodded. "Okay. I don't have to be at work until 4 in the afternoon tomorrow, so I'll see you later I guess. Give me a call when you're off work."

Addison nodded as she walked Alex to the door, shutting it softly behind him. She leaned her back up against it and slid to the floor, sighing as she ran her hands through her hair. "Shit."
