"I was a surgeon before I came here: I was.... a little too good at what I did, and in some ways, not good enough," he says, looking into his teacup, running a finger along the rim, and from his tone of voice, it's clear what he might mean by "too good" at what he did. "I... had a fondness for classical music and dark things, but having a fond ear was as far as it went." He doesn't add that he is-was one of the dark things, and that he might actually be the scion of some dark angel.
