Hunk was in an academic groove, in a deep flow state. That was hard to do given all the hustle and bustle, so he was savoring it. And sure, he'd noticed that Bonnie had crept into the room, and written some deeply troubling titles on that board. But she was small and quiet and could fly, so he really wasn't paying attention to her. When that cookie poked him in the cheek? Well...

"Guh-aaaaaa-!!" Hunk let out a yelp as he jumped in the opposite direction, except then it turned into a near-soundless gasp, and then his hands clamped over his mouth. They were in a library, after all. Sadly, momentum from that initial startle started to overtake him, and he fell backwards to the ground with a thud. At least the chair didn't topple.

"H-Hi, Bonnie..." It was about all he could wheeze out, between calming the adrenaline, trying not to shout, and attempting to make as little of a scene as possible. He was probably failing, but he was on the ground. Barely anyone could see him there.
