Hannah's eyes jerked open in utter surprise, grabbing at the nearby wall to make sure she didn't lose her balance. It took her a moment to realize what had happened and that it wasn't anything horrible; it was simply a case of someone knocking into her.
"Oh, I'm sorry. I just - I needed a bit of air, so I stepped out." Hannah moved to scramble and help pick up the things that had fallen. She didn't instantly recognize the woman or who she was, but she seemed familiar. Hannah still felt a bit shocked at the collision, but she was just happy it wasn't Winchester. A small disaster was tolerable. Though, as an afterthought, she added, "Are you okay?" It should've been her first question, but she hoped it was unnecessary as a whole anyhow.
