Hmm lets think and bump this article! Then use some (perhaps) Who logic - It may be flawed but I like the theory, and would love some feedback.
I think -
She cant be a time lord as Doc would know, unless she is A)human form via a chameleon arch and then doc and she’ wouldn’t know themselves. She could theoretically be the doctor in a future incarnation, but likely that would prove suicide to the series so I say no to that. Doctor witnessing his demise, and flirting with himself is a bit strange.
Anyways,
So is she his mother? I doubt it, a wife or lover, I guess so. We’ll find out soon, I don’t think she is a form of him. Most likely she learns Gallifreyan in some mind bonding experience later in the series finale that allows her to send him a message in the episode we have just seen.
What I find more interesting is this….
My mrs has a lovely two part theory we’d like to share,
Part 1
This advances the theory that she is somehow responsible for patient 0 escaping, and maybe even causing the whole of the problems in time that are thematic through this series. That is why there are reoccurring cracks, and no memory of the daleks. In prison for mucking around with time? Again who knows.. Helps to explain why she was in prison, and might have no idea of events that can or cannot be changed as a time lord would.
Part 2
This is regarding a comment that was made in the library episode that seems quite pertinent, (paraphrasing) I would say she said
The Doctor, with a new haircut and a suit, visits River Song and takes her to see the Singing Towers of Darillium. He gives her his Sonic Screwdriver.
This is the event before her death in library episode. So……
My mrs thinks that the doctor will die and regenerate either at the end of this series or shortly through the next, and a new a new doctor will undertake the events where River meets him for the first time. If you look at the timeline river is in, according to library episodes the events unfold in this order for River.
1 She Meets the Doctor for the first time.
2 Has an adventure with the Doctor at the Bone Meadows.
3 Has a picnic with the Doctor at Asgard.
4 Breaches the Byzantium and is rescued by the Doctor
5 River Song and the Doctor are at the crash landing of the Byzantium.
6 The Doctor, with a new haircut and a suit, visits River Song and takes her to see the Singing Towers of Darillium. He gives her his Sonic Screwdriver.
7 Tries to send 'her Doctor' a message via the Psychic paper, asking him to come to the Library.
8 The Doctor, whilst travelling with Donna Noble comes to the Library and meets River Song (for the first time from the doctor’s point of view.)
9 She Proves to the Doctor how important she will be to him by whispering his true name in his ear.
10 Sacrifices herself to save the Doctor and the Library.
11 The Doctor beams River Song from a Neural Relay in her sonic screwdriver into the Library he gave her in event 6.
12 River Song's brainwaves live on in the virtual world inside the Data Core.
This means Tennant has taken care of 7 to 12 - and Matt Smith has/will take care of 4 and 5. When River meets Tennent for the first time from his point of view, she infers he is not her doctor, or not yet her doctor. And when Matt Smith meets her for the first time, she says she recognises him from the book, even though it is not the first time that she has met the doctor, it is the first time she has met Matt Smiths’ (Now remember the first and last time she meets Tennant is those two episodes last series)
This must mean she will meet another doctor as yet unknown to us, who will control events 1 2 3 and finally bitter sweet episode 6 . The nature of the program and that of actors aging (namely River not being able to play her youngest self in five years from now) makes the Mrs think Matt Smith will only be doing one to two series, and we may even have a surprise regeneration at the end of this or near the beginning of next series.
Who knows.
It would be nice telly to have a surprise regeneration out of the blue, with no-one knowing its arrival. Last episode of this series is airing in June, new season filming in June? Just an idea. No offence to matt smith, but Eccleston only did one, and a new older actor would fit in with the quotes river has given in the past, and the theory Moffett is creating.
Listen we just had an idea, and we had a theory about Wilf ages ago and everyone seemed to like it, plus I love the feedback, so let me know what you think.
