So, I was watching the DVD's of Doctor Who - Season 2 and I recognized a familiar face. Did anyone else realize that our current companion (Freema Agyeman AKA Martha Jones) was in the season finale as one of the computer workers at Torchwood? I read the character she played was supposed to be the cousin of Martha Jones.
I say that's not fair. You're not allowed to have the same actor play every role in a TV series.
