He stumbles when his boot passes through her and then she's gone, completely imbalanced by the force he put behind it not meeting anything but air. He catches himself before he falls completely at least, hands out as his eyes dart around him. Trying to find her. When he does, he bares his teeth at her and retreats. Six feet is not enough in this moment, and he slides back to the edge of the circle, glaring deeply at her the entire time.

Only once he's there does he actually take a breath and try to process all that. His anger doesn't fade at all here. What she's told him is that they have to kill all the monsters, and that at least some of the kids are monsters. He has dealt nearly the killing blow on all of them, and the idea that she or the Protector or both of them have tricked him, and all the knights before him, into this is making his stomach twist into knots. And she has the pure audacity to sip coffee instead of explaining herself.

He thinks his disgust is completely justified, so no, he's not going to answer her question. He's going to demand, "You tell me. You're the one looking for allies."
