nealieissquealie asked: When did O'Brien become such a favorite?

Thomas: First year I was here...I was a snotty little shit, you know? But she was kind to me. Kind might be stretching it. She found out about my...thing, and she didn't turn me in to anyone. Didn't even judge me. And plus we had bonded over hating everyone else. Looking back on it it wasn't that good.
