In their final confrontation Davros was trying to make the Doctor admit that compassion was a weakness, so was that not his way of trying to get the Doctor to admit that he screwed up in not killing/abandoning him as a child when he had the chance?

I'm going cross-eyed thinking about this. LET'S WAIT AND SEE.

In summary, I too loved everything, ESPECIALLY THE NEWFOUND CLARA/MISSY BROMANCE. BEAUTIFUL.
