Well that was a blast from the past…
Following a fakeout where it’s theorized that the mysterious woman popping up in episode after episode may be the long lost Susan Foreman (last seen in the episode “The Five Doctors” in 1983), it turns out they were the villain Sutekh, last seen in the episode “Pyramids of Mars” in 1975.

Season Finale next week!
Could be the Rani as well…
Or, it could be Susan. They know about the Tardis, and they’ve been pretty passive about interactions with the doctor or Ruby. And unlike a lot of people on other forums, not making tea is not necessarily evil. It’s rude, but it’s not evil.
I’m thinking Susan too or maybe The Doctors daughter.
We saw with River Song that she went from Melody Pond to River Song due to a miss translation, so Mrs. Flood has to be connected to River somehow.
Or maybe River, somehow?
