And on the subject of Davies killing off Doctors, he really did crank the emotion up to ten when writing David Tennant's final episode, didn't he? It's difficult picking the saddest moment from 'The End of Time'; the victory lap, saving each and every companion of his era is particularly heartbreaking, as is meeting Rose again, who doesn't know who he is. The lottery ticket that he gives Wilf is a lovely moment too the fact he borrowed the pound from Donna's dad is a teary addition to the scene and when Ten finally stands in his TARDIS, panting and watching helplessly as the regeneration energy swirls around him, so many Who fans were in floods of tears. But a moment please, again, for the performance of Bernard Cribbins. Tennant's final scene has been talked about over and over again, but what about the moment when Wilf and Ten are sat talking on the spaceship? "I'd be proud... if you were my dad," the Doctor muses, before Wilf bursts into tears begging, "Please don't die. You're the most wonderful man and I don't want you to die." It's a episode full of horribly heartbreaking moments, that's for sure.
