Gives a whole new meaning to playing chess with yourself. A great look at a post-war Doctor through the eyes of the darkest pre-war Doctor. Just one thing to nitpick:

"Green, that was new. His eyes had always been blue, one constant in his ever changing appearance."

I don't count Richard Hurndal's eye color as canon since he was not the original actor. While green IS a new eye color to the Doctor, he was born with brown eyes.

Aw! This was really good, I enjoyed it!

Cool
