Panic set in when she took his wine glass - because what was he going do with his hands now? He had no coat on, so he couldn't shove his hands into his coat pockets, and he didn't want to go start picking up her belongs and fiddling with those. And besides the room didn't seem to have much for him to pick up and fiddle with. He was tying to come up with some possible excuses to flee (foot cramp! 'Oh shit I left my soldering iron turned on back at my apartment!') because he wasn't sure if he was ready for ... well anything that might come next.
(It had been ... a while. But he also dind't want to assume that anything was going to happen other then a nice tour of the room.)
And then she was kissing him.
He put his arms around her, and kissed her back. Trying not to think about how long it had been, or the fact that she was a better kisser then he was and - he was mostly able to avoid thinking about the fact there was a picture of Bruce Wayne on the wall over there. The guy who Ted kind of looked up to business wise. And his picture was over there on the wall.
Okay he had to turn around because he couldn't be facing the picture and kissing her. Even with his eyes closed, the picture was still facing him. So he tried to keep kissing Babs, and at the same time sort of move himself to the left a little bit ...
