Mark Gatiss does indeed like Three a lot:) I got the miniscope ref too! And Hai! Spoons & Pat spotting.

I liked the Prince of Thieve (as my cinema ticket had it) ref:D

Twelve may not want to get caught up in being a "hero" because that's a label and he'll have to behave in a certain way and doesn't want to be trapped by that, espc if he also doesn't think he is a hero/good. And it sort of does away with free will if it's all written by the Oracle (or something) and the chance of different stories. And I'm big on different stories!
