Okay, listen to this...
In Doctor Who Series 2 Episode 2 'Tooth and Claw', the Tenth Doctor arrives in Scotland, 1879. The Tenth Doctor is played by David Tennant, who is Scottish but uses a London accent for the show. When he shows up in Scotland, he uses his actual accent. It's cool, I know. He says his name is James McCrimmon. Jamie McCrimmon was one of the Second Doctor's companions (*gasp!*). What's more, James Tennant was the jewel cutter of Queen Victoria, and oversaw the recutting of the Koh-i-Noor, both of which appear in the episode :O. Coincidence? I think not...
