There's no surprise in being right, but it is interesting to watch Inej's surprise. It sets off another series of questions in her own mind. Because he's been here a while already. Months and months.

"Yeah. Same world."

Beat.

"Same job."

It's a flash decision, not thought about before she says it, and without even looking down again at her tattoo. But if the girl has one of those then she likely knows why he put it there, what it's for, and what Dean does. It's all just logic dominoes. At least it's a lot of what she tells herself. "I'm Jo."

There's a raise of eyebrows as the returned question, more than words.
