(S02E12) The penultimate episode of the second season delivers in a big way, both setting up the season finale as a major event with huge stakes for Captain Jack as well as delivering some great looks back at what brought each member of Torchwood to the team. Using the framing sequence of a massive explosion, we spend the majority of the episode in Lost-like flashbacks.

What's so brilliant about the stories we get is that in most cases the back-stories are nothing like I would have expected for that character, and yet at the same time it so perfectly serves the personality and drives of each individual on the team. Suddenly, Tosh's meekness, Ianto's eagerness and Owen's boorishness make perfect sense in the context of their past experiences. Even Jack's cavalier behavior and obsessive dedication to Torchwood make sense considering his own history with it. What they've managed is to add more depth to our relationship with each of the individual Torchwood members just in time for all hell to break loose in the finale.
