Well, yeah. I mean, I left it that way for a reason, you know. I don't know how much he's told you about himself, but it's generally not something that you'd want to find out on your own. There's too much that he could have found at Torchwood, that's why I thought it was safer where he was, in his flat. I even hid all of his diaries from him when he wasn't looking so he couldn't go through those.

((Sulu's welcome to try, but like I said, Jack's being thick at the moment, and probably won't get it unless it's spelled out for him. His reasons were somewhat noble, even if not exactly well-planned. xD;; ))
