Series 2 Episode 12: Army of Ghosts

Summary:
The Doctor and Rose land in London to visit Jackie but something strange happens. Ghosts appear everywhere and not only in the UK but on the whole world. For the Doctor the strange figures don't look like ghosts and he tries to find out where their signal comes from. Accidentally, they take Jackie along on their journey, which brings them into the Torchwood Institute. There the Doctor and Jackie find out about the ghost shift and how Torchwood gains energy. Meanwhile, Rose is able to walk freely through the Institute and comes to a room with a strange sphere in it, which nobody can open. The Doctor's fears come alive when some programmed people from Torchwood start the ghost shift again and Cybermen from a parallel universe appear in Torchwood. But this is not all that the Doctor and his companions have to face.

This is the first part of the final two-parter of series two and the last time Rose is the Doctor's companion. It's an interesting story and the ghostly forms are a brilliant idea. I guess everybody has lost someone and they just want to believe that their loved ones came back. Torchwood is playing with humanity here and they don't know what they are playing with. Finally we see Torchwood in this episode after all the hints during series two. It's a bit crazy that they see the Doctor as their enemy and admire him at the same time. This is the first episode after the relaunch of Doctor Who in which we have two of the Doctor's big enemies: Daleks and Cybermen. But the episode is not only exciting but also a bit sad because we know that Rose won't be travelling with the Doctor anymore. Freema Agyeman, who plays Martha in series three, has a role in his episode as well and plays her cousin who is killed by the Cybermen.
