Yeeeeah, Gwen is so not my favorite character. You know, I really did like her back in early series 1, when she was still fresh and basically your character that was the access card to the world of alien fighting and kickassery, but once she started having an affair with Owen and lusting after Jack when she had a fianceeand basically telling Jack she'd drop Rhys for him if he gave the word ON HER WEDDING DAY and being unbearably self-righteous and dealing out orders like she'd been around for years and years, I lost my liking of her. To say the least.

I don't know, you might not be the only one. I'm definitely not one.

The Doctor gets his hand chopped off and regenerates it in The Christmas Invasion (Christmas episode before the start of series two) and it's brought up gain in Utopia, The Sound of Drums, and The Last of the Time Lords :D Let me know if you need help on that post, as I am very happy yo help.
