It really would. If the somewhat elderly man were to fall behind, confused after an alarm, and disappear into the tunnels while hallucinating? Ignored by the rest of the group? Nothing good comes from that. Even through personal discomforts, everything works out better if Sky walks with the rest of them. A small remove, a few dozen paces back, is probably good enough if he stays in sight.

"Of course, they're small and fuzzy, it's not their fault some carry... diseases." For his part, Russell nods as he waits for the loiterer's approach, standing comfortably tall despite the overhead stone... and the possibility of more bats swooping.

Logically, he knows the concerned parent in that group - warning kids not to touch any bats if they can help it, they carry rabies - has some merit to it. The chances of passing the disease to humans is slim, and vastly slimmer yet with how aggressiveness bats are... but it feels oddly distant. Maybe he's just distracted by how, that he's stepped away from worrying about the old lady's wellbeing, the caves really do feel comfortable, just like they did before.
