After closing the front door of the apartment, Katherine could have screamed so loudly that the whole apartment block would have heard. She was freaked out by one kiss, one stupid and pointless kiss over a bit of friendly banter that was because of her flatmate having the sex life of monkey at the moment. But ever since Chase and Cameron filled for divorce, Katherine has been trying to keep friendship with Cameron while living with her ex but that hasn't been the best of friendships. But when Cameron found out that Chase was moving in with Katherine and her sister that's say that the argument caused the whole of the ER to stop and watch this girl fight over a guy.

"You're sleeping with Chase" Cameron had shouted to Katherine

"Excuse me?" replied Katherine shocked and very confused by the comment from Cameron

"You heard me, how dare you let Chase moving in with you while your sister is living with you as well"

"First off, why are we having this conversation across the ER? Is it so you can try and embarrass me in front of my fellow work colleagues? This is not going to happen as you where the one who kicked Chase out in the first place and he needed a place to stay and he came to ask me because he knew I need a roommate and being a friend I let him moving in to the spare room. Why would I sleep with him as I know he's your ex husband and I wouldn't because I am your friend and could do something like that." Katherine said with mixed emotions of hate and shock at one of her friends who think of her as slut as such for supposedly sleeping with her ex – husband.

After the blow out with Cameron in the ER, Katherine hadn't spoken to her in a very long time even when Cameron had moved hospitals and then completely out of Princeton-Plainsboro. With Cameron having quit her job as a senior attending physician, there was a job going and of course Katherine applied to fill that position but never got it from lack of experience.

Katherine was walking down the stairs of the apartment block as the lift wasn't working; typical she thought whenever she need time to think the lift wasn't working at all. That's what you get for living in the cheaper end of Princeton.

She walked through the reception area of the block and saw that Mike was manning the reception tonight. Katherine and Mike had been an item when she first moved in the building this was when she had moved over to the Princeton-Plainsboro Teaching Hospital to finish off her 1st year of training as a doctor. But the relationship with Mike didn't last long because Katherine had found out that Mike was cheating on her with someone else in the block, well this must be the new place to pick somebody she thought. But Katherine wasn't in the mood to hear how Mike's new girlfriend was like and made a swift walk to the front entrance of the building.

Just as Katherine had got through the entrance, there he was standing under the street light with the snow falling around him like he was an angel or something with the light being above his head and acting as a halo.

"Katherine" the man from her past said

"Matthew, what are you doing here and why are following me?" Katherine said with her voice showing signs of being shocked and scared.
