Tim uses his torch to get a closer look around the otherwise dark cavern. He has his flashlight, as well, to be safe, but he's keeping that hidden away in his belt for now. He doesn't move quickly, and keeps the fire relatively close to him-- he doesn't want to aggravate anything in the cave.

He just had to get a closer look at what was here. There has to be something... If nothing else, this was a logical place for something to be hidden, being a low traffic area.
