Anthony Edward Stark

Bruce trails in Tony's wake and ends up pacing the room rather than trying to find a place to sit or joining Tony on the bed. He's both surprised and not by Tony's attitude, just as he's both surprised and not by his own level of guilt for this situation.

"Con: she was literally born yesterday." Looking for a distraction, all he's got is picking up the towel Tony just tossed away earlier. "Pro: not living a nightmare where one wrong step could mean I'm the one locked in the trunk while Hulk takes the driver's seat for good."

Okay, now what's he supposed to do with this wet towel? Good call, Banner.
