2.)Brewster has lived a secluded life in the "background." He's always tried to stay away from others because he doesn't want to risk the chance of hurting himself and possibly the ones he gets close to.
Brewster should try not to create a relationship, because getting close to someone, like he does with Bronte, is undoubtedly going to lead to pain.
3.) He has to decide whether or not to take the pain away from people. He could help so many, but at the risk of his own health so he obviously has to make some extremely tough decisions when he comes across people in pain.
4.) The perspective it is written in. Brewster lays out everything he's feeling in lists and in poems and other ways that aren't seen in other novels. I liked the way he used the lists to organize how he is feeling. Organizing it myself was hard when it was made so clear that Brewster was having trouble organizing it himself.
