Doctor Who: 10 Mrs Flood Theories You NEED To Know

10. She Picked Up The Master’s Tooth

Officially, Mrs Flood first appeared in The Church on Ruby Road. But could she actually have made her debut one story earlier?

In The Giggle we learn that the Toymaker fought the Master and imprisoned him in his impressively-shiny gold tooth. Following the Toymaker’s defeat, that tooth was retrieved from the UNIT helipad by a very well-manicured hand... that appeared to be floating off the side of the building?

We’ve been here before of course – a similar-looking hand rescued the Master’s ring following his first encounter with the Tenth Doctor, allowing him to live on – so it seems someone is planning to resurrect the Master all over again, and a character as seemingly nefarious as Mrs Flood may just fit the bill.

Maybe she’s the one who picked up the tooth in the first place (with the aid of her Mary Poppins-esque umbrella) and she’s just waiting for the right moment to use it.

Another possibility is that this resurrection has already taken place, and Mrs Flood actually is the Master. Maybe there was a chameleon arch situation going on, and seeing the TARDIS disappear in The Church on Ruby Road triggered Mrs Flood's Master memories back?

This would be quite a different and unusual depiction for the Master, and though a somewhat predictable twist, you can't deny that Anita Dobson would absolutely slay as the Doctor's arch-frenemy.
