Clara 'Oswin' Oswald

If you're reading this and my view of my reader is anywhere near accurate, then you've already watched the Dr Who episode "The Bells of St. John" (that's today's for those of you to stupid to think (which is of course non of you, but I have to be prepared for muggles to come along now and again)) If you haven't then go fucking watch it! Both to avoid the spoilers and so what I'm saying makes sense... Ok are we all caught up now? Good, let's proceed.
No wait, one more thing before we do. Do you think because Matt Smith is the youngest Doctor ever that someone high up decreed that the companions must be younger and hotter than ever before? I mean when they unveiled a leggy redhead in a policewoman's uniform I was pretty certain that was not to be topped, but then, well... this happened:

I mean seriously! She is properly hot. The only reason Jenna Louise Coleman is not on "the list" is because she's on both my father's and brother's, if there was ever something that you shouldn't share with your family, it's list entries (find the post "the Lovell list" to explain that)
Anywho, now I actually am going to get to the actual timey-wimey, nerdy-wordy things I came here to say. To avoid (or possibly create) confusion We'll be using this system from here onwards:
Clara=Victorian
Oswin=Dalek
Jenna=This episode (and series, but that's not relevant yet) (yes I know that's the actress's name but what other option do I have? "Oswald"? No, that's an old man's name! Don't be so silly)
The most obvious question the writers have made us ask is "Are Clara, Jenna and Oswin all the same person?" which obviously leads on to the more interesting "If yes, how is she resurrecting?" or "If no, what connects them?"
I know I came here to express my theories and thoughts about these questions, but I can't answer the first of them. She's met the Doctor for the first time 3 times now, but she never knew him beforehand. So this means that surely they're not one person being resurrected, otherwise Oswin and Jenna would remember the meeting Clara had with him wouldn't they? So they must be different people surely?
However, it seems that knowledge is passed between them. Clara is in the past and not a genius, Oswin is in the future and she's able to hack a whole dalek prison at will. Jenna, at the start of the episode, knows nothing about computers, she then gets uploaded, downloaded and all the other sorts of loaded (that sounds rude now I write it) and becomes a total screaming genius but modest and a tiny bit sexy, much like Oswin is. That implies some sort of consistent conciousness that allows knowledge to be passed down on a linear timeline. So maybe they are the same person but why is knowledge passed and not memories?
Besides, there are a few subtle differences between the 3 of them. Oswin's first name was, obviously, Oswin, Clara's middle name was Oswin, but then Jenna didn't recognise the name. How can a name flit in and out of the timeline for a person/people?
Let's be honest, I've answered nothing have I? I've just listed all the options. Well to quote Neil deGrasse Tyson and Jean Valjean "Sometimes, one must be content to love the questions themselves." "The truth is given to us all in our time, in our turn." So put the kettle on, put your feet up, and watch the pretty woman and the mad man in a box.
