Two ongoingDoctor Whomysteries - Mrs. Flood’s identity and the whereabouts of the Master - may be connected, and a compelling theory can explain why.Doctor Whoseason 14’s endingleft many questions answered, but none more intriguing or significant than Mrs. Flood. Anita Dobson’s character has cast an ominous presence over Ncuti Gatwa’s time in the TARDIS thus far, and many compelling theories about Mrs. Flood’s true nature have arisen in the absence of concrete details.

Arguably the most compelling ofDoctor Who’s Mrs. Flood theoriesclaims that she’s a godlike entity, perhaps a member ofDoctor Who’s Pantheon, who is obsessed with the Doctor. The Pantheon connection would explain how Mrs. Flood knew about Sutekh in season 14, while proof of Flood’skeen interest in the Doctor can be found in how she speaks like a third-person narrator, dresses like former companions, and lives next door to Ruby Sunday. All signs suggest Flood is some kind of omnipotent observer whose favorite source of entertainment is watching the Doctor flit around time and space.

If Mrs. Flood Is A Doctor Who Fan, Did She Take The Master’s Tooth As Memorabilia?

“A Fine Addition To My Collection…”

Mrs. Flood is far from the only dangling plot thread heading intoDoctor Whoseason 15. Back in the 60th anniversary special episode “The Giggle,” the Toymaker recalled beating the Master and trapping them inside a golden tooth. Following the Toymaker’s own defeat, said tooth was knocked loose and picked up by a mysterious hand with painted red nails, butDoctor Whoseason 14 all but ruled out two popular hand-idates in Jinkx Monsoon’s Maestro and Susan Triad. Nevertheless,it remains distinctly possible that the owner of that enigmatic hand was none other than Mrs. Flood.

Adding the Master - the Doctor’s infamous arch enemy - to her collection would represent an extremely impressive acquisition.

The theory thatMrs. Flood is a massiveDoctor Whofanmakes the idea of her being the unidentified dental thief from “The Giggle” even more plausible, as it gives Dobson’s character an actual motivation for wanting to own the Master.Doctor Whoseason 14 was extremely meta in terms of its fourth wall breaks andBridgertoncosplay aliens, so Mrs. Flood being a hardcoreDoctor fan would fit perfectly inside that framework. With that in mind, Mrs. Flood could have seized the Master as a piece of memorabilia.

10 Doctor Who Details That May Reveal Mrs. Flood’s Identity

The mystery of Mrs. Flood’s identity is a hot topic in the Doctor Who community, but certain details may play a part in helping reveal who she is.

Just like regular fans collect toys and merchandise,Mrs. Flood could own mementos from pastDoctor Whoadventures. She appears to have swiped Clara’s sweater and Romana’s white coat already, and adding the Master - the Doctor’s infamous arch enemy - to her collection would represent an extremely impressive acquisition by any measure.

Mrs. Flood Can Write Her Own Episode Of Doctor Who

The real question is whether Mrs. Flood would be content keeping the Master on a shelf, or, like regularDoctor Whofans, she would rather see them locking minds, engaging in a good vs. evil battle over the fate of the universe. Mrs. Flood could, therefore, intend on releasing the Master, then gently pushing them into the Doctor’s path before sitting back with a tub of Pantheon popcorn and watching the action unfold alongside the audience.

The Master might be too consumed by their rage against the Doctor to care whether Mrs. Flood is pulling the strings.

Mrs. Flood pitting the Doctor and the Master against each other would create a curious dynamic between the two Time Lords. Defined by pride and ego, the Master would loathe being controlled by a higher entity, and might resort to cooperating with the Doctor as a means of bringing Mrs. Flood down.Doctor Whoset a precedent for this when the pair eventually worked together against the Time Lords duringDavid Tennant’s regenerationepisode, “The End of Time.”

Ncuti Gatwa’s Doctor Who Season 15 Hint Makes A Major Mrs. Flood Theory Way More Convincing

Actor Ncuti Gatwa provided a hint about the story for Doctor Who season 15 at SDCC 2024, which supports a popular theory about Mrs. Flood.

On the other hand, the Master might be too consumed by their rage against the Doctor to care whether Mrs. Flood is pulling the strings. That element of unpredictability would make a Doctor vs. Master fight, with Mrs. Flood as referee, a fascinating proposition inDoctor Whoseason 15.
