That's one way to forcibly dislodge the alien's sudden sullenness; Glacius' brows shoot up in alarm as Carlisle slips and immediately moves to assist, swooping down and grappling one of his partner's arms should his own limbs prove unable to catch himself.

This land is harsh and requires our attention to traverse safely," Glacius warbles, keeping one hand in Carlisle's while he adjusts the human's pack for him. Then he gives him a once over. "Are you alright?"
