Poor Ianto. Tosh and Owen died at the end of series 2, now Ianto's dead. Sad times for Torchwood. I really wish Clem hadn't died, I really liked his character, but it was key for him to die to stop the 456 at the end. Fortunately only 3 kids died rather than 10% of the child population of Earth. Poor Steven being made by Jack to sacrifice his life for the other children.
If you were in Jack's boots would you have sacrificed your grandson's life?
