I really quite enjoyed the New Year’s Day episode of Doctor Who, Eve of the Daleks. At the end of the credits we see a preview of the next (one off) episode and we get to see a Sea Devil.
Back in April 2010 I was discussing the first episode of season five.
An excellent first episode, though a couple of things caught my eye. Firstly in the scene where the Doctor asks is the planet Earth protected we see a (classic) Sea Devil. This to me is a bit of a clue that we may see them in a future episode.
Well we didn’t get to see them back then.
Looks like we will be seeing them in 2022.
