Oh – forgot to say – maybe that’s why River is in the mix in the first place with all the attendant “is she his wife/Amy/enbodiment of the Tardis etc – whist we are all chattering about this it deflects us from the real issue which is that the Doc is not the Doc. One thing about Mr. M – he don’t do things by halves!! And even if I’m completely wrong (which, given SM’s amazing ability to blind-side us all in the past, I undoubtedly am!) – it would make a hell of a story some day, hmmm?
Cheers!

Promise this is the last one – just had this thought – what if the Doc – or Amy – is STILL inside the Pandorica? Might explain the plastic centurion’s re-appearance later in the series.
I’ll get me coat….

Okay -so I lied! But I’m just getting the hang of all this theorising and it’s great fun so just to throw another item into the mix – why the hell was the Doc hanging out of the Tardis door over London at the start of last series? It looked like he’d been in a hell of a fight – and he has re-generated inside the Tardis before without wrecking it so what went wrong this time? The new trailer shows what looks like the old “coral desktop” tardis which caused many theories about Chris E or David T returning but remember – the “coral” version also belonged, albeit briefly, to Matt S.So – If me previous theory runs true to form was the Doc fighting the evil version of himself just before we started series 5? That would be the only logical way to change time and undo the wrong that the doppelganger had done – kill him (it) before these events began and the best time to do that would be in the post regeneration fugue state. Also, look very closely at the scene in the trailer and pause it if you can – that looks like Rory in the shadows watching events and just possibly Amy too – how are they there before he’s even met them?
Full circle anyone?

Looks like this is becoming an obsession but was just downstairs putting a pizza in the oven when this little doozy popped into my head.
51st century – StormCage prison where River was held. Who else was there? The alternative bearded Doctor from the new trailer. Haven’t worked out why he’s there yet but wouldn’t be surprised is he was blamed for doing something his doppelganger did.
Doc uses the fobwatch to become human. River is (I read somewhere with usually reliable information) human. Does the future Doc become River with little or no knowledge of his true self but with an implanted mission/false memories given by himself to her – to find his past self and stop all the evil that the doppleganger will/has caused?
Reasoning?
The Daleks, when placing him in the Pandoricon, stated that it has confirmed that the Doc caused the cracks which will destroy the universe.
The exploding Tardis exploded at EVERY point in time and space – VERY IMPORTANT!!!
By placing the Doc in the Pandoricon they prevent the Doc becoming “evilDoc” and so save the universe. They DON’T say it was THIS (ie Matt S. Doc that did/will do it – see the Tardis comment above – may be a future evil version of the Doc who is too powerful to take down so they get him BEFORE he becomes too powerful.
Who could unite the Daleks, Cybermen et al into a single force? Only the true Doc who was helping them to defeat his evil self and therefore re-write history (Steven M’s mantra!!) so that the universe under the influence of the evil Doc would never happen.
The oft-commented upon watch which Amy and River seem to wear – the Fob Watch in another form?
The “possibly future wife” idea implanted in River’s head explains why she knows his true name and smooths over any possible incongruities (“Spoilers!! – handy get out clause!!) by showing the future Doctor trusts her – but the Doc also knows his true name and if he is really River…then he/she has all the knowledge he needs to fool his past self.
Now I don’t believe SM will do a “Dallas” and end it with the events or series 5 never having happened so for that reason I don’t thing the Doc we have been following is a complete doppelganger but someone/thing else got into his head when he re-generated (which explains the OOC moments which have been dismissed as sloppy writing (Can’t see that happening with SM to be honest) – the OOC bits are the other part of the Doc’s “passenger” surfacing briefly.
Knowing the Doc, and using the re-writing time idea, the future bearded Doc eventully gets back to the Tardis as he was regenerating from David T and he fights off the villain (Omega) who is about to take over the Doc at that stage.
Hmm – getting complicated innit?
OK – tea time!!!

Oh yes – “Prisoner Zero has escaped!” Could that be the (bearded) Doc escaping Stormcage before he becomes River?

And…who could blow up the Tardis? Or should that be WHO could blow up the Tardis? None of his other foes could do that – not even the Time Lords (we have to assume that or someone would have done it by now) – but it has been established that the Doc can – again it may be an effort by his future self to destroy the bad version before it gets too powerful. Also, just HOW does an exploding Tardis end the universe? Surely all that would do is release the time vortex (which I always envisioned as a quantum singularity held inside and manipulted by the Tardis) and we know the Time Lords have control of the main vortex (the untempered schizm) so something just doesn’t add up.

Oh I just can’t put this down – 12 seconds into the new trailer (the 60 second vesion) – is that a time crack the Tardis is flying through )or has just flown through from their pov.
Also on the bbc site is a wee mini interview with Karen and a tiny extra clip where she’s screaming and looks like she’s firing a gun – normal type gun judging from the sounds – so maybe she kills the Doc? That would make a VERY dramatic scene and we know the series is very good at high drama these days.
OR
Maybe she kills Rory which would explain the look of anguish on her face (nice acting there Karen btw!!)

@BillStorie
Prisoner Zero is the multiform featured in the eleventh hour.

And the timelords almost certainly dont control the vortex anymore, for obvious reasons.

Other than that, nice theories. Just please try to condense them into fewer comments…

@BillStorie
Sorry for double post.

The tenth doctors regeneration was extremely powerful, and thats why the TARDIS was damaged so badly.

But I wonder whats with that coral TARDIS?

Sorry about waffling on so much – will try to keep it short and sweet.
The creature we refer to as Prisoner Zero is indeed a multiform so it could make itself look like the Doc (maybe to make the Stormguard staff think he was still in his prison as part of his escape plan) – then it found the crack and escaped. It did seem to know Matt S, was the Doctor and also said “The Doctor and the Tardis don’t know…” but it had never seen either before. Odd that.Almost as if it had met the Doc before?

Point taken about the Timelords but I always thought the schizm was a natural event which the TL’s gained mastery of so it must have existed in that state before they came along and harnessed it for time travel so if a Tardis blows would it’s singularity not just return to being part of the schizm? Afyer all, if one Tardis can destroy the universe, why hasn’t the schizm already done that before the TL’s tamed it?

Not being funny and I am far from an expert here but why was this regeneration so powerful? Was that explained in the episode or is it something we have all just assumed to be the case? I only mention it because I know Steven M loves to “play” with assumptions and some of his best “Who” moments have been revelations that things are not as they seem.
btw – if that was explained onscreen then sorry for being a dumbass and missing it. Must be getting old.

At the risk of waffling on too much again – I PROMISE this will be the last long post – The villain (I’ll call him Omega for the sake of argument) has to break into the Doc’s Tardis as he is re-generating at the end of series 4/start of series 5 in order to become pat of the Doc’s new self so he uses his Tardis to get him into the Doc’s Tardis, after which Omega’s Tardis would fall to Earth over London (where the Doc was hanging out of the doors!!) and the emergency crash protocol kicks in thus it becomes the second storey of James Cordon’s one-storey house in “The Lodger”.
Still doesn’t explain the impossible second flight of stairs in Amy’s house though – but I suppose if a perception filter can make it look as if a Tardis is a second storey it can also make a third storey invisible – at least from the outside – and from the inside the filter would also make it un-noticed by Amy and her Aunt so what is up that flight of stairs? Another Tardis? THE Tardis? Still needs a bit more of the puzzle to fall into place yet.
Can anyone add any clues I’ve overlooked?

Quick one this – the new trailer shows River firing her gun in a circle but check the background – she’s actually in the time machine from “The Lodger”. Starting to fall into place a bit more…

The time machine in “The Lodger” – could it be a SIDRAT from the War Game during the second Doc’s run? That would also explain the cavaliers and Nazis in the trailer and also the image that looks like Amy running down a corridor in an old type Tardis.

And clones – of course we have a story involving clones this season and Omega did create a clone of the Doc once before in the 5th incarnation which ties in with my doppelganger theory.
Maybe.
I’ll shut up now.

I think you’re overanalyzing a lot, all tyhose clips and story ideas come from different episodes, not everything is going to tie into the grand plot twist. In ‘The Doctors Wife’ the TARDIS enters voidspace and lands on a junkyard planet, where they meet Idris. It is theorized that this planet is a TARDIS, or Idris is a personification of the TARDIS. This is the epoisode where we see the coral console room, and amy running down the corridors, apparently there will be many scenes in the interior of the TARDIS.

Moffat has stated that ‘Humans will have been subconsciously aware of The Silence for many centuries and that awareness will have manifested itself in paintings such as The Scream’

Let’s have a look at The Scream shall we?[/color]

Look at the top left of the painting. What do you see, particularly about what the figures are wearing?

There’s no way that’s a coincidence.

Is it true that the second part to next weeks episode will be showing the day after the first part shows if that makes sense

Revenant is right of course – I’m probably adding 2+2 to make 5. I had discounted the possibility of the coral console room being part of that story because the whole idea of a planetoid in void space being the “bones of a Tardis” has been done before in the 8th Doctor’s story “Neverland”. That story involved the Oubliette of Eternity which Timelords used to wipe criminal Timelords from history but in reality dumps them in this anti-verse and the planetoid is the remains of Rassilon’s Tardis, with him inside a zero room awaiting rescue. I always wondered how Rassilon suddenly came back to lead them out of the Time War – maybe this tale will explain that?
But it probably won’t. Fun though, innit?
ps – checked the official BBC schedules and there’s no episode listed for Sunday 24th. Maybe someone got confused with the BBC3 schedule which normally repeats the Saturday episode a day later and follows it with DW Confidential?

@BillStorie
Its fairly simple really: The tenth doctor held off the regeneration for ages so he could say goodbye to his friends, so he practically exploded when he released the energy.

Hmm – there’s a clip from that same episode where they find an Ood with a damaged voice orb which the Doc fixes and suddenly it emits a cacophany of voices which the Doc says belong to Time Lords. That’s getting pretty close to “Neverland” for co-incidence and although it has been fervently denied it would be a logical place for Paul McGann to pop up, even if in flashback as the Doc’s memory of the events was later erased in the 8th Doctor adventures. That would fully bring the Paul McGann audio stories into the main series which would be brilliant!!
One can but hope.
