New theory for Clara

What if Clara isn't anything by an ordinary human being...that just so happens to be in the right place at the right time?

Also I don't think River Song herself, or the Downloaded River shows up at all. I actually think its the holographic interface on the TARDIS.

I also think Clara jumps into the time vortex and goes back and saves the Doctor many many different times. 

(Yes I am aware there is a collection of blu ray disks that happened to be released here in the US. No I don't have one. I got all this information from the trailer.
