Gyre doesn't know he didn't hit his head! All he sees is his very sick looking, possibly concussed ally take a sudden dive. He grabs the back of Garrot's shirt, but isn't able to stop his fall and keep his own balance. It doesn't do them any good at all if Garrot gets hurt from falling and then so does the kid, so he stabilizes himself first.

Adrenalin jumps up into his throat, and he nearly jumps down the hill, sliding into place beside Garrot. He crouches and carefully settles the kid off to the side, guiding their head down so they're... well, mostly comfortable anyway. They're still laying on rocks, but they're not hurt.

Then he grabs Garrot's shoulder, squeezing it. "Are you okay?" he asks sharply, bending close to grab Garrot's face and look into each of his eyes in turn.
