Oh man, I'm glad I've finally caught up on this. Had to re-read the whole thing, really, but so worth it. Very curious, eager to see what's going to happen with canon here. It's Ianto who's got my attention, really. It's like he's the vertex of the building whatever-it-is (a bit literally in this one), and between Jack and Gwen, I wonder if he's not the sanest.

Kind of a frightening thought, that.

I loved the observation of Jack being a little bit not-right when he gets the box of tech out.
