This was truly a fantastic episode, I was kind of unsure about the concept at first, but was really well played out.
It really brought out another side of the Doctor, as all these new ideas and possibilities started unfolding.
I'm kind of unsure how she survived, but I hope we see Jenny again in the future (either in Doctor Who, or another spin off??? Did seem to hint at another spin off to me), and I'd definitely like to see Jenny and the Doctor finding each other again.
I found the ending with the Doctor and the gun absolutely brilliant, because despite everything, and looking rather threatening, he still pulled through without killing, which I reckon is a tru testiment to the Doctor's strength.
All in all, I reckon that this is the best episode of the series so far. It seemed different to what we normally get, but I loved it.
