As grateful as he is for the buckskins, they aren't his and Jack begins to notice that nothing of his is around. "Oi... Look, mate, I'd rather make do with m'own trousers if..."
But the brave leaves him alone to change, so Jack does so. He puts on the trousers and shoes and finds the leather a bit scratchy for his taste. Particularly in the more sensitive regions. They'll do, though, and he makes his way out of the tent. He smiles at the children, but only to placate them. Everything else about his demeanor says they're tiny vermin that may infect him with something. His hands are kept up and away from them and he tries to move out of the swarm. He doesn't care for the way little fingers trace over his tattoos or how other tribesmen are laughing at him.
