Bucky was taking stock of the batch of new arrivals, or he would've seen her coming and gotten out of the way. As it was, he didn't even move when she smacked into him, instead blinking at her... creative expletive. "I'm fine, sorry I didn't see you," he replied, offering what he hopes is a reassuring smile, and crouches down to help her gather her things. He's only got the one flesh arm these days but his smile is warm, at least. "Are you okay?" He knows he's about as soft as granite.
