Honestly? Leonard wasn't sure what in the hell was going to happen. They could both walk out of the damn place at any time. Be completely and totally vulnerable elsewhere, except that he liked her. She liked him. This whole damn situation was scary if they were really thinking about it, but he meant it. They could let their damn insecurities get in the way.
So, those eyes watch her every movement as she closes the distance between them. Until she's practically a breath away from him. "Okay," he says pushing himself off the wall and practically in her personal space, his eyes searching hers for a moment before kissing her.
