I just finished rewatching series four of Doctor Who. And you know what? I hope it's not the last we see of Donna.
She became part Time Lord. She said that the part she got was his mind, all his knowledge. But maybe she got more then that. I don't think that by removing all her memories he took away all she had of a Time Lord that she gained during the "biological metacrisis". I'm sure they could be a way to bring her back. A part Human part Time Lord on earth. Something is bound to happen. And I say that not only because I'm a crazy fanboy that loves her. Maybe a little. But also because she's my favourite companion up to now. Plus Donna Noble is an awesome name.
Catherine Tate only signed on for one year according to wiki. But come on! Make her sign another contract!
Is it Christmas yet?
