1. Doctor Who has a scientific explanation for things happening such as ghosts, and nothing really supernatural happens unless alien species are behind it. If Rose narrated the start of it and she has "died", how can she be talking anyway? I think she means "died" in a different manner, as it would be a huge spoiler to put one minute into the first part of a two part story.
2. I thought the inclusion of Torchwood this episode was good, just wish they hadn't put it in the previous episodes apart from Tooth and Claw.
3. The Cybermen want to join forces with the Daleks, nothing has been said about the will of the Daleks. And the Cybermen are from an alternate reality, changing their nature slightly.
4. Once again, Rose might not die.
GOod to know that woman meant to be the next assisstant died.
