Clara is the daughter of the T.A.R.D.I.S.

Well, sort of.

We know the T.A.R.D.I.S. exploded through every point of time and space.

My thought is the splinters ended up inhabiting (for lack of a better word) a human. In this case Clara’s mom, Ellie Ravenwood Oswald.

The raven is a symbol of a messenger from the cosmos and messages that are beyond time and space are carried in it’s wings. When the Doctor said he didn’t like taking the T.A.R.D.I.S. into battle, Clara asked “Why? Because it’s made of wood?” (aka ravenwood).

Clara’s famous “It’s smaller on the outside!” line made me laugh, but when I started to think about it, this could be something passed on from her mother. If her mother is a fragment of the T.A.R.D.I.S., technically, Clara would have experienced the inside first, then the outside so of course it would be flip flopped.

Technically, each fragment is part of a whole so even though the pieces are at different points of time and space, they should be “leading” the same lives. Hence why they would all have a daughter named Clara. That’s why she keeps popping up in all these different places.

And a fragment wouldn’t be as taxing on a human body (unlike what we saw with both Rose and Idris).

If the T.A.R.D.I.S. doesn’t like Clara, it could be because “she” recognizes a part of “herself” and can’t comprehend it.

There’s a lot that Clara’s mom could have passed onto her, even if Clara isn’t aware of it. That could explain why she said “pond” on the one word test, has all of this computer knowledge (once kickstarted), and why she would be considered such a prize to the Daleks.

Ultimately, the only thing that has ever been consistent on this show is the T.A.R.D.I.S. (and hence Clara’s connection to all these number references is through her mother)

Clara’s mom is very important, and not just to why Clara is the way she is.
