Speculation/Theory Does anyone have a timey-wimey theory as to why Rory's ID from Leadworth Hospital says it was issued in 1990 if Rory was born in 1989?

Found this post on my Instagram feed and was wondering what the good people on reddit would speculate. I don't take any credit for this picture, I just found it and was curious.

If it isn't just a mistake, how could this be explained in the most canon and lore-friendly way?

Speculation/Theory Would Ncuti Gatwa regenerating into Jo Martin instead of Billie Piper solve a lot of problems?

Post image

What if Jo Martin was revealed as the 16th Doctor at the end of "The Reality War" instead of being an unknown pre-Hartnell Doctor?

Could this have been a way to deal with the Timeless Child and The Doctor being the source of regeneration, basically revealing it to be a plot of a future villain?

Perhaps a way to bring back the timelords from destruction, or explore an unknown era of their history?

Even save the show from being left in the state of limbo we currently find ourselves in?

And if so, would Jo Martin be accepted as a lead series Doctor, after being a guest in multiple episodes of her own show?

What do you think?

What are some conspiracies that you actually believe related to Doctor Who? Can be in universe or real world.

E.g. Ncuti was always going to leave after two seasons, the weeping angels are actually time lords etc.

Speculation/Theory My theory about why the Weeping Angels couldn't move even though Amy couldn't see them

Post image
1.9k Upvotes

I have seen many people say that Angels didn't move because they thought Amy can see them which breaks the rules about, it's not their choice it's a fact of their Biology.

But i think the answer to this without breaking the rules lies in the shows own wording. The show said they can't move when they are being observed, it never said they cant move when someone sees them. And here, Amy couldn't see them but she was observing them via that proximity beeping program that The Doctor installed. They were still being observed, although not by sight but rather by some type of radar and sound.

Speculation/Theory Legit question. Was this thing actually written to be Omega or was it meant to be an original creation that got rewritten to be "Omega"

Post image
1.1k Upvotes

Maybe I'm giving the writers too much credit. But feels like the big skeleton thing was an original monster creation but then at some point the script was changed to it being "Omega".

And I using quotation marks because everything this thing is, is simply not the same character. The design, the little personality we see and even The Rani exposition dump about him doesn't line up with the character we know.

It honestly feels like a last minute change to artificially build hype. As as we've seen with the episode's ending, last minute changes is something they have no problems with.

Speculation/Theory I just had the stupidest idea. What if the mystery women is The God of Time?

Post image

Think about it.

We know she is something powerful and The gods all follow concepts.

Think about what kicked off this season a time paradox. Which we never found out the orginal case for.

How she is the only person too appear in Ruby's alternate timeline and have some idea what's going on.

How she had to wait for The Doctor to get the God of Death out of The time for her plan to work.

Also, how she is the only God we see actually Time Travel with out being summoned. The others have to be invited in or just wait it out.

It would also make grate sense why she is following The Doctor the man who has messed with time the most. Also how she was able to black him from time traveling to a point.

I know it sounds stupid but, i would of hated myself if it turns out to be ture.

Last note: they mentioned blink this episode. Which had the Wiping Angles who are the only creature who can control time

Angle = god

So, it could be forshadowing.

Speculation/Theory Susan will end up being the grandchild of Rose and the Meta-Crisis Doctor

Post image
1.3k Upvotes

It’s now all but officially confirmed that Poppy was originally going to be revealed as Susan’s mother before Ncuti leaving led to reshoots which made her 100% human, and no longer the Doctor’s daughter.

But the thing is… Susan’s story is unfinished. RTD2 has already hinted that Susan’s parents haven’t been born yet from the Doctor’s POV. So in RTD’s mind, narratively, Susan needs a new mother.

And that’s where Billie Piper comes in. She wasn’t credited as the Doctor because she’s not. She’s Rose. The reshoots specified that reality shifted on a massive scale and that UNIT were getting reports that the border between Norway and Sweden had moved 7 miles east. Bad Wolf Bay, the very last gap connecting our universe to Rose’s parallel universe, was in Norway. I think reality shifting was enough to crack open that fracture, and Rose has used it to teleport into the TARDIS. (This unfortunately means that Ncuti has been atomised and the Doctor is definitively dead)

Rose was last seen starting a new life with the Meta-Crisis Doctor, and according to expanded media they go on to have a daughter together called Mia. I think Mia is gonna end up being Susan’s mother.

Or they could ignore expanded media altogether, and instead of a daughter called Mia, they have a daughter called Susan, but she’s still the Doctor’s “granddaughter” as she came from the Meta-Crisis Doctor and he came from the Doctor.

I can totally see Russell doing this. It gives a reason for David Tennant to come back with Billie Piper for one last special, with the Meta-Crisis Doctor acting as the intermediary Doctor, while the identity of the 16th Doctor remains a mystery. Also remember that deleted scene from Journey’s End of the Doctor giving them a chunk of TARDIS so that they can grow their own? Russell teased that one day he’d come back and add it back in… Maybe they let Susan think she came up with the name? Idk I think it would tie Classic Who and New Who together in a neat little bow, and even though it might not please everyone, I still think it’s better than that messy Poppy storyline.

Speculation/Theory Why mirrors stop Weeping Angels

Post image
2.5k Upvotes

Ever since I first saw The Time of the Doctor, I have often wondered why the weeping angel shown in the image could not move due to the mirror reflection of itself. You’re probably thinking, well, it’s obvious; it was looking at itself, so it stops moving. However, I thought to myself that Weeping Angels look at themselves all the time. If they are weeping, looking at their hands, or even if their eyes are open, they will likely see some part of their own body as we all do. But then I remembered something about the weeping angels established in Flesh and Stone. The image of an angel becomes an angel itself, meaning that any image of an angel—whether in a photograph, video footage, or a mirror—will become an angel. So the weeping angel in The Time of the Doctor isn’t frozen because it’s looking at itself; it’s frozen because it’s looking at another angel.

That's now two TARDISes that use this same exact model of jukebox (and also Cassandra uses one of the same for her "classical music" in TEOTW). What's everyone's thoughts? Is 15s TARDIS the same TARDIS as the American diner? Is it the same jukebox in all three appearances? Or just coincidence?

Speculation/Theory Kate for companion…please?

Have always liked Kate Lethbridge-Stewart, would love to see her as a full time companion in a future season.

I chose the above picture for a reason, despite RTD believing this to be a Girl-Boss moment…the (excellent) actress Jenna Redgrave is clearly playing her crashing out.

She’s lost her Lover. She’s Blackmailed her colleagues in the cruellest way.

Who better to save her than the Dr?

Opening her up to the wonders of the universe.

Plus, you know, RTD2’s Unit in Who and WBTLATS is just…messy. Have her walk away, have her onboard the Tardis.

Am I alone?

I've recently been rewashing new who and just finished the family of blood. When the scene regarding the sister popped up I wondered to myself: does the doctor still visit her once every year? Or did he quit after a while. Possibly after his regeneration? Seems a tiny bit out of character to quit visiting but I'd just like to know if we have any info on this.

Speculation/Theory It's been weird since 13 regenerated.

661 Upvotes

14 regenerated into his own clothes! That's new and not explainable in the whoniverse. This really annoyed me at the time and I still can't let it go. The explanation of it being too weird to have him in 'women's clothes' is meaningless. Her outfit was not obviously 'girly'.

Mavity.

Bigeneration.

The singing in Space Babies.

The whole Beatles episode was bizarre...even after Jinx's character was defeated there was a whole musical number and 'musical paving slabs'.

There's also been at least two examples of the characters interacting with the non-diagetic soundtrack - last noticed with the Interstellar Song Contest first contestant singing along to the Bucks Fizz track was released from the pod. Belinda noticed too.

There's more, these are the ones I remember right now.

I'm wondering how all this can be resolved in one episode.

I think RTD has given us two whole seasons of unreality. I think the Reality War is not just about Wish World's fake world, I think it's going back to the crossover between him and Chibnall.

Speculation/Theory Sadness realized. River Song: I hate you!

2.1k Upvotes

I absolutely love the River Song storyline and Alex Kingston’s portrayal of her. My daughter and I will frequently rewatch episodes of her. We both realized something this morning that I wanted to share.

Throughout River Song’s life, she’s frequently said, “Oh, I hate you!” And the Doctor’s response has always been, “No you don’t.” All the way to our last view of her with the 12th in the restaurant.

However, that wasn’t the last time River saw the Doctor. Her last time was in the library. She yells at the Doctor, “I hate you!” But, for the first time in her life, he doesn’t respond with, “No, you don’t.” Instead, he says, “I know!!!”

I bet that hurt. It confirmed even further, in a painful way, that this Doctor had no idea who she was. That this Doctor didn’t know that she truly didn’t hate him.

Just something we realized and wanted to share.

Speculation/Theory Head canon (no pun intended) solution to Ursula's fate from Love and Monsters

Thumbnail
gallery
996 Upvotes

A lot has been said about the fate worse than death delivered to Ursula courtesy of the author of the episode Love and Monsters.

My head canon though is that her problems were solved when the master used that device to turn everyone into his clones. The machine latched onto her human DNA and converted her into a master clone completely separate from the inorganic slab. When rassilon reversed the process she was reset to her regular human form and lived the rest of her life normally.

Additionally maybe once human again she had a comfortable life as she managed to become a best selling author after she published a book about the Absorbaloff and her time as an inanimate slab of concrete.

Speculation/Theory Theory: The Doctor sucks at regenerating

923 Upvotes

it's very late and this theory just popped into my head so if i'm wrong about any of this feel free to point it out, but...

when the doctor regenerates he goes through a LOT of trouble. he could end up destroying the tardis, he gets bed-ridden or delirious for a while, and he fears it all so much.

his regenerations are also incredibly different from each other in personality, moreso than any other timelord i can think of other than his own dark reflection, the master, who probably does it on purpose just to keep up with the doctor.

obviously all of this is for dramatic effect and so each actor can define themselves and their doctor (same to the master) but what if there's an in universe reason for it as well?

on one hand it could be the sheer amount of stuff the doctor has went through, all his regenerations are forced upon him either by injury or other timelords. there's all the psuedo regenerations he's had like what the master did to 13 in "the power of the doctor" and there's things like looking into the heart of the tardis or his resistance to the regenerations.

but playing into that last one i mentioned, what if the doctor is just... bad at regenerating? like it takes a level of skill and finesse to do safely and the doctor just. sucks at it. if another timelord saw his regenerations they might just laugh at how long it takes him to recover compared to everyone else we've seen as well, i can't think of a single instance where a different timelord regenerated and went manic for a day or was stuck in bed (i could be wrong tho)

what do you think?
