Bruce was lost in his own world, trying to calculate where he was and look for some answers. He felt lost and cold and a little annoyed. The world had once more played one of it many practical jokes on him, and he felt that this was just a little much. He was used to waking up post-Hulk in odd places, but without even an incident? This was pushing it.
The sudden impact of a woman into him was enough to bowl Bruce over significantly, and make him startled utterly. He lay there, staring at her for only a moment before old habits kicked in. His heartbeat had pounded for a long moment, but stilled, and he smiled, for she seemed hardly a threat, and some small chivalry in him demanded he held her. Moving, he did his best to help her collect her things, and he smiled faintly at her question.
"No, but my problems aren't from your impact, ma'am. Just having a really odd day." He nodded to her, and figured that would be the end of it. Most people with any sense would probably run from a strange man in a lab coat who even had his identification card still on, hanging from it's clip.
