"That actually has a decent chance of working," Gerard admitted, glancing at the firebird. It had taken to flying up as high as it could and then diving down to batter itself against their shield charm, hissing in outrage when the three wizards within failed to burn to a crisp. "Not crazy about having to drop the shield to let the spell through," he continued, making a face at the bird. "But it seems like we're out of options. But there's no fucking way I'm letting you risk yourself, William. This is my job, I've got experience with the Killing Curse. I'll do it."
Gerard wasn't going to say it, but he was pretty sure being a werewolf gave him -- not immunity, exactly, but a better chance of surviving a clip from avada kedavra than either of the other two had. And if not... well, Willam might have disturbing images of Mikey floating about his head somewhere, but he was a good guy, a better guy than Gerard could ever be, and so was Brendon. If taking a Killing Curse was the best way to get the two of them out of this room and back to safety, it'd be worth it.
"Besides," Gerard admitted ruefully. "Brendon's better at charms and I actually have no bloody idea how to cast a mirror spell. So, uh. Hopefully one of you two does?"
