Carlisle notices the distance Glacius puts between them, figuratively and literally, but he can't parse it out at the moment -- he's too exhausted from his ordeal, too relieved Glacius hadn't met a terrible fate, too paranoid with what happened to his twin. For all he knows, the other Carlisle could be lurking around any corner, just waiting for them to let their guard down.

So he lets Glacius do the guarding -- offering Carlisle a sense of safety is one of his true talents, after all. "I- I want to go home," he says tiredly after a moment, wiping his face again, feeling ink and blood in his hair. He makes no attempt to get up; he knows he hasn't the strength to do so on his own, and is sure Glacius can see it as well, so he instead reaches for the alien's arm, so certain his friend will help him to his feet.
