User:SOTO/Forum Archive/The Reference Desk/@comment-15860425-20130818185120 I can't remember the name of the episode where the Doctor had a robotic creature attached to one side of his face and it was making him have split personalities. I can't seem to find the name of it anywhere and it's been bugging me. Thanks :)
