Weird thought, previous episode title and something that missy said about ‘Was my Boyfriend Mean to You?’ and ‘I Love the new accent, Think I Might Keep It’

Is it another case of a Human Avatar of the TARDIS, though a darker, sinister one, like the Doctor has the Valeyard…

I’m getting a definite villain vibe; but villain with a complicated history. Like the Master, but not the Master. I mean, there were moments when I actually liked and empathized with the Master. I get the same kind of feeling with her.

I think she must be a Time Lord, or at least some kind of serious Time Lord connection….

We know that the TARDIS has a female personality.
We also know that “she” chose the doctor, not the other way round.
Is it possible that “she” has somehow developed a split personality? Could Missy be the darker side of that split?
Her comments about her “boyfriend” fits.
If she isn’t, it would make a good storyline.

I think Missy is the new Master.If Clara not exist because Clara is a young version of Missy

Okay, theory time, so I think the “I hope my boyfriend wasn’t to mean to me” line from Missy and the “Clara, I’m not your boyfriend” and “I never said it was your mistake” lines from the Doctor to Clara are connected. Seriously i will be crushed if Clara doesn’t exist because if I go bakc to watch an episode, say The Time of The Doctor for example, it will be hard to listen to her say “Please don’t change” when its not really her and the only way I will be okay with it is if Missy is controlling Clara. When Clara does eventually leave the show , and we all knkw she will at some point don’t deny it, I would hope she leaves the TARDIS crew to go get married to Danny and I hope she doesn’t get killed of because then she could come back like Martha did in The Sontaran Stratagem. But because it is a Moffat one she will most likely die, and if she does I hope her last words to the Doctor are “I love you, and one thing, Run, run you clever boy and remember me” that to me is the only way they can end it and it would be really sweet and emotional, and if she dies I want her last words to Danny to be “Danny, I always put you first, I love the Doctor, but I love you in different way, in a special way, and you will always be mine”. So that was long and rant-like but I really hope it is happy end, probably won’t be , but good to have hope.

This may be one of the weirder theories, but I think Missy is an aspect of the Doctor that split off during his regeneration. The last thing we heard Matt Smith say is “miss you!” – could that even be related to her name “missy”?

Missy looks an AWFUL LOT like “Miss Hartigan”, (Dervla Kirwan) from the 2008 Christmas special “The Next Doctor” with David Tennant.They both sport an umbrella,and dress in Victorian attire.She helped the Cybermen, in the end she was sent into the time vortex by the Doctor.Did she meet The Great Intelligence, (Simeon) there?There is a connection to the computer GUS.

@Ben

Interesting idea, especially as I’ve never liked that Moffat made the cracks in the universe swallow the whole of “The Next Doctor” events.

If Missy were Miss Hartigan, it would also link her to the Cybermen present in the screencaps.

Not sure if that’s who she’ll turn out to be, but a great thought anyway.

@Valcoor
It may not be the Doctor’s TARDIS.When Clara entered the Doctor’s timeline the first thing she did was redirect the first Doctor to a different TARDIS.

@Ben
The clear implication was that she was sending him to the familiar TARDIS with her reference to the navigation system.

Missy… The Mistress. Romana was refered to as The Mistress once? E-space.. Alternative universe/Pocket Universe. Gatekeeper of the nethersphere/The Warrior’s Gate?
Has Missy actually killed anyone? On the trailers she seems to be helping the Doctor in an odd way. Could Romana have regenerated into a more toughened, no BS, arrogant TimeLady? Oh wait.. The 12th Doctor is a bit like that, right?

Now (speculation set to high level) Seb..?
What if Seb was short for Mr. Sebastian? What word can you spell from some of the letters in MR. SEbaSTian..? Anyone? Anyone..? Bueller..? Bueller…?

Hi fellow who aims I know we wondered for a long time who’s missy well when I found out I was blow away I did not see that coming the master as a female I pictured it I (shamelessly) dreamt of it. But never believed till now quite timey Whimy lol

my theory is that Missy is shout for Mistress which would be linked to the master or even a female form of the master…but how maybe a he got another TARDIS and has left the time bubble but that’s not possible is it? No it cant be…

But what if the theoretical bubble is braking then what would happen,could the doctor save use the same way he did last time?

MISSY IS THE MASTER!!!

@William
yes but how?

omg MISSY IS THE MASTER!!!!!!!!!!!

@Leala some sectors of time-lords can regenerate into the opposite gender :)

Any time lord can turn into a woman

I don’t care what the show says, Missy is the doctor. Look at the eyes. Maybe the Master is the doctor in a child from, made just so time doesn’t collapse. That would explain how the doctor knew the master as ac child. Think about that.
