So... I just finished re-watching Torchwood, Children of Earth. During "Day 5", Frobisher is repeatedly described as "a good man" by his assistant. She says it about four or five times. We know The Doctor thinks of himself as a good man, and given what we know what is coming for Capaldi I'm wondering if just maybe this was all planned from a long time ago.
Could Frobisher have actually been The Doctor turned human with the aid of one of those fob watch thingies? What if after shooting his family and himself he regenerated... What if we've already seen the death of the next doctor?
I know... Probably not likely given the way they present a Doctor Who as a family show, but watching it back,
