He feels about Caleb the way he once felt about Brother Luke: someone in whom he had, rashly, entrusted himself, someone in whom he had placed such hopes, someone he hoped could save him. But even when it became clear that they would not, even when his hopes turned rancid, he was unable to disentangle himself from them, he was unable to leave. There is a sort of symmetry to his pairing with Caleb that makes sense: they are the damaged and the damager, the sliding heap of garbage and the jackal sniffing through it.
