Creepy mansion, check. Group of unwitting young people, check. Strange old caretaker of the house, check. Yep, we’ve got all the pieces of the classic horror story here. Just add one Doctor looking to solve the mystery. Jinkies!

The biggest mystery of Doctor Who this series though is still what’s in the vault. We know that the Doctor made a promise to keep whatever is in the vault in the vault. We know that he said he wouldn’t leave earth or the vault, but the Doctor being the Doctor that hasn’t lasted. We also know that whatever is in the vault it’s alive because Nardole was talking to it at the end of the last episode.

There doesn’t appear to be any clues to what’s in the vault in the trailer for “Knock Knock,” which means it’s probably not in this episode. The next episode after this week is “Oxygen” and that one will take us off world again, so perhaps that’s when whatever is in the vault makes its move.
