Which dwarf goes into the dragon’s cave with Bilbo? Why? (2 points)

Balin entered the cave with Bilbo, so they he might call for help if needed.

He did not expect a chorus of volunteers, so he was not disappointed. Fili and Kili looked uncomfortable and stood on One leg, but the others made no pretence of offering - except old Balin. the look-out man, who was rather fond the hobbit. He said he would come inside at least and perhaps a bit of the way too, really to call for help if necessary.
