Zarin
Zarin doesn't care which tunnel they choose. But he wonders why they need to track at all since they saw the creatures run into the tunnels.
Zarin is familiar with sunrods, and has even made some himself with alchemy. Does he recognize that as a sunrod? If it is, he'll take it (unless someone else wants it). If he can hold a torch and a sunrod in the same hand he will, otherwise he'll tuck the sunrod in his belt. Then he'll search the cots too, while Poto is looking for tracks.
