Being Nine years old, she can squeal pretty well. And such was her reaction to Paul McGann’s appearance I had to pause the video to let her finish.
How would that regeneration play out, I wonder. Could it cancel out the War Doctor (but not his actions, due to the war being a fixed point in time)?
Could it possibly lead Eight to regenerate into Nine, as the War Doctor would now be a paradox, and Eight no longer had a controlled regeneration, but rather a random one?
Just a delirious post I made in the early hours of waking.
