Maybe there was something spooky over there suddenly! What if it was something he needed to bark at ferociously!? What! If!!

That possibility still wasn't entirely ruled out even as she slammed in to him. There was definitely a wobble and a sway, but this time he managed to keep them mostly upright as he spun around a bit to find his footing again. "Oof-- whoa, hey. Hey. It's okay, I've got ya." He'd wrapped those protective arms around her, looking around the kitchen for any potential source of these troubles (?).

"You okay?"
