Heh, Ten is just what fandom conveniently calls him because he's the Tenth Doctor. When you get to the people who've been watching Doctor Who since they were toddlers (Daleks still scare the crap out of our lot, but they will probably not intimidate you), you've seen a couple of Doctors. So we say 'Nine', 'Ten' etc to avoid confusion. It's just convenient that his surname happens to be Tennant :P.

Hee, I am very very dead. So yes, I need a Doctor... *pretends to be unconscious and innocent*

Yay! I can play with Gael and will let you play with Zach Braff in return. Harems are so damn practical!
