[torchwood]

I KNOW I've read that fic before, I remember she got all cocky thinking she'd aced it and Jack tells her she's done the worst in Torchwood history or something. I've got the links to 2 fics and I think it's one of them, but they're both so long I'm not going to read all the way through just to find that part.
