[ They're right - he isn't aware, and for a human, a head is an absolutely vital organ that can't be destroyed. He applies the same thinking to the gems. Incorrectly, it seems. When Cairngorm clarifies that they can rebuilt, and that Lunarians are the ones who stole Phos's head, he breathes out a sigh of relief.

(Does that change that Cairngorm broke their head? No - nor does it really ease the fresh memory of shattering it that Lupin now shares. But it means that it at least wasn't a fatal injury, and he can forgive lashing out in a moment of anger in a second.)

This is a lot to process in a few seconds, even for him, but he does his best to compartmentalize what he just saw for the moment, with his immediate fears of misjudging Cairngorm soothed, and focus on the new problem: he's hurt Cairngorm's feelings. It's obvious in every inch of their body language and in their poisonous tone of voice, and on one hand, he feels quite defensive - what was he supposed to think, seeing something like that? - but the much greater part of him is suddenly worried he's done something he can't take back. ]

[ He remembers now that he'd just been swinging by to check in on them; he hadn't made it further than their doorway before this all happened, and now, he stands his ground firmly there, hoping to block Cairngorm from running off. ]

Don't just run away. [ a beat. ] ... Please.
