Yeah. See, I can do certain things. And there's a group of people who can do the same things I can. And I don't get along so well with that group. If they knew where I was, they'd try to kill me. Or worse.
When the Purifiers came around, they already knew who I was and what I could do. Which is why I left. Didn't need that shit on top of everything else. Came back when it was safe.
