Timey Wimey

Lately, I have been rewatching some episodes of Dr Who from the past few seasons. At the moment I'm just at the begining of David Tennant's version of The Doctor travelling with Donna Nobel. So last night when I couldn't sleep I watched 'The Fires of Pompeii' and was surprised to see a very familiar face playing one of the soothsayers.

Its Karen Gillian (aka the current companion of Matt Smith's Doctor, Amy Pond).

This probably shouldn't be surprising as Martha Jones appeared in one episode as her cousin the season before she actually became Martha Jones. Donna also appeared in a single episode (although actually as herself and with a much bigger part) before she too became a companion. So perhaps in order to become a regular companion you have to go through a sort of interview process by appearing in a single episode to make sure that the cast and crew can all cope with you? I'm sure people would be willing to do pretty much anything in order to score a gig as a companion :)

Oooo, I just had a thought. Wouldn't it be cool if they wrote a storyline in which the Doctor crosses his own timeline at Pompeii and it actually is Amy Pond there pretending to be a soothsayer. How awesome would it be to have David Tennant's Doctor accompanied by Donna and Matt Smith's Doctor accompanied by Amy in the same place at the same time, trying not to bump into each other. Awesome!
