Torchwood: Children of Earth is on BBC America this week, Monday thru Friday at 9PM. Last night was Day Two, in which we saw a bomb blow up the hub, Jack naked and in chains, Gwen, Rhys and Ianto on the run. And Ianto saves Jack with a front-end loader. Did I mention Jack was naked? Here is the preview for Day Three.
