Glacius has to think about that admission for a good second or two. Of course he knows he's different, but that word usually carried with it more negative connotations-- he was alien, he was other. He was a creature that didn't belong. But the way that Carlisle says it... it makes him feel like he's being embraced not just despite it all but because of it, and that causes a surge of emotion within the alien that he's not entirely sure how to identify. Whatever it is, he's glad that Carlisle is looking away, because he can feel it causing a purple blush to darken his cheekbones underneath his icy skin.

"I, u-uhm, I've never had anyone say that to me before," the otherworldly being responds, scratching at his mandibular support bashfully. "I have made so many friends here, people that I feel so blessed to have in my life... and yet there is a little part of both my hearts that wonders how much a being like me, so different from everyone else in this place, can really mean to them. I know that if given the choice, the humans here would likely rather spend time with a member of their own kind... and that is fine, it is only natural. But to hear my difference be celebrated like this, it... i-it..."

He loses the words somewhere along the line as that feeling flares to life again, like a cold and bracing wind inside his soul. Glacius fights hard to identify it, unsure if it's a sense of attachment, or gratefulness, or... or something along those line. Whatever it is, he's decided it's good. The alien lowers his head, the long curve of his neck bringing his forehead closer to Carlisle's. It's a gesture that he's initiated a couple of times now, but right now there's a whole lot of intentionality behind it.

"... It means a lot to me," the alien finally manages to finish, whether or not his friend chooses to accept the contact.
