Cite some examples that point out the relationship between Billy and Boyd.

Billy, as the older, is somewhat protective of Boyd but he does not really take any overt protective action. In fact, his protectiveness is almost off hand, but there's no doubt about his stand where Boyd is concerned. When the Indian says that Boyd should stay behind while Billy goes for coffee, Billy straight out refuses. Later, Boyd's saddle will be broken and Billy will stand up for him when their father questions them. Another aspect of the relationship is that Boyd seems somewhat resentful of Billy's role as the older brother though he is dependent on Billy. Boyd wakes one night to find that Billy isn't in bed. When Billy asks what woke Boyd, he says that Billy did. Billy counters that he could not have made any noise because he was not in the room. Boyd says that is the point.
