Steve smiled and blushed a bit when she showed interest in the picture. He let her look at it closely, running a hand through his hair. He took the picture back, and when asked what else he could do, he simply shrugged. "Well, I can't get rid of all my secrets, Miss Carter." Steve put aside the notebook and took a position next to Sharon. "I heard that with time, people start to know each other's secrets when they're in a relationship--" Steve stopped what he was saying. He gave a nervous laugh. "I mean, if we were in a relationship, I didn't meant to say that, or... assume that we were...Sorry." Steve started to ramble, and soon started to trip on his own words. 

He guessed they never announced that they couldn't see anyone else... Or how long this would last. Steve never thought of it that way, though. As he's said a lot of times, he has never been in a relationship, and what he had with Sharon was the closest thing to one. He liked the thought of Sharon being his girlfriend, even if they couldn't publicly announce it... but he didn't want to jump in to conclusions. He liked to think that she liked the idea too... Now there was no avoiding the conversation, right?
