Major spoilers ahead.
Torchwood Day Two was even better than Day One, and so far Day Three has topped both of those combined. Davies successfully manages to raise the stakes in each successive episode, which can only mean a massive climax on Friday night. I can't wait!
Day Two was definitely Gwen and Ianto's moment to shine. Jack blew up at the end of Day One, so with him (temporarily) out of the picture, Gwen and Ianto are on their own and on the run. Gwen and her husband, Rhys, stowaway on a potato truck on its way to London. There, they meet up with Lois Habiba, a new girl in the Home Office who's starting to wonder for which side she's working. With a little help from her, they go off to rescue Captain Jack, only to find that he's been imprisoned in a block of concrete.
Cue Ianto! He decides to steal the entire concrete cell with some heavy machinery conveniently left behind by the people who poured the concrete. Oh, and Gwen blows up the concrete mixer to cover their escape. They toss the concrete block off a cliff, and Jack emerges ... naked, of course.
