Everything has kind of caught Dean's eyes as he tries to take things in, so he's not entirely surprised that he's managed to accidentally bump into someone. though his hand will go out to Satoko's elbow or arm to ensure that she's not too jarred or thrown by the bump at the same time.

"I'm sorry too, I wasn't entirely watchin' where I was going." There's a small smile from Dean, apologetic. "You okay?"
