Whether he's injured or not isn't immediately visible, but his shoulder is smoking, the cloth of his shirt blackened. Considering he put what fire did manage to catch out with a bare hand, Strange can probably guess (and be correct) that there's been some burning. Childermass leaves his hand over the burnt patch, though, as if trying to keep whether he actually is hurt or not from being noticed.

"Remember when I asked you not to set the audience on fire?" He growls the words through clenched teeth, using his free hand to push himself back up to sit. While he's not trying to make a show of any pain, oh boy, you'd better believe he looks pissed for all of, perhaps, ten seconds before he tamps down on it.

He's not going to yell at Strange. He can deal with this. Just count backwards to one and--

There. He ends up breathing out a sigh instead of snapping at the other magician any further and glances over at his shoulder. Not smoking anymore, so that's good enough for him to shake his head at Strange.

"No. It's fine." Yes. Absolutely fine. "You have no idea how far the seats are from the center, do you?"
