Instinctively, once he hears the word "duck," Rex does just that, covering his head with his arms. At least those old army skills come in handy sometimes. He peeks up, just in time to see a streak of pink about to make a faceplant with the wall.

And then it vanishes, only to reappear, flailing, several feet off the ground and thennnn...

Ouch.

Rex watches with more fascination than concern, eyeing those wings in particular. It-- no, wait, she, that's a girl-- was like a life-sized fairy from a story book.

After a moment of staring, Rex gets back up, pulling gaze from her wings to her face.

"No, I'm fine," he answers, then realizes he should probably reciprocate. So, that neutral expression shifts of a furrowed browed look of concern. "Uh. Are you... okay? That looked like quite a fall."
