[Glacius appreciates the unspoken physical gesture of support nearly as much as he appreciates Carlisle denouncing his double. Given that he's watching his partner's face intently, and that his glowing green eyes allow him to see perfectly well in the darkness, he can see the way his expressions flickers with... something. Sadness? Hurt? He's not sure, he just knows it isn't good. And then a though occurs to him, one that realizes he should have had a damn long time ago, probably would have had if he hadn't been so preoccupied with the clergyman nearly up and dying on him:]

He said something to you before I came in, didn't he? He wasn't just lurking and hiding... you conversed. You must have. [And if Carlisle's double had delighting in tearing him down, he can only imagine how damaging his double had intended to be.]
