You had only been there about a week, Nick had been keeping a very close eye on you. He wasn't the one who would save you, but he was on that mission. And he was one of the first initial people from SHIELD that you had had contact with. Nick knew it was his job to help you eventually reenter society, but as of right now he didn't think you were stable enough.

So, right now he just walked into your room, after knocking of course, wanting to see how you were doing. He knew that there was a file on you at this point, but he hadn't had the chance to read it yet.

Nick: "What are you doing?"
