The BBC has announced who will play the part of the new Doctors assistant. Her name is Karen Gillan, a 21 year old Scottish actress. Karen's character will be Amy Pond. She had appeared in the Pompeii episode of Doctor Who as a soothsayer but you would've had to know who to be looking at to spot her. She was heavily disguised. Its not the first time that a minor character went onto play a major role in the series. Colin Baker played a guard in one episode of the series then later came back to appear as the sixth doctor.
