LOL! Yeah, Tegan's a bitch, and Jo is, well, dumb. I'm more of a Liz Shaw man, myself. The first "smart companion", not counting that Susan was his grandaughter, and given the chance, is probably just as cunning as The Doc himself.

And, enjoy the original Master (not counting 'The Monk' character from Hartnell's days...which many fans believe is an earlier regeneration of The Master). Roger Delgado was a class act, and simply made that character. Anthoney Ainely, his successor, is a buffoon compared to him. No other actor has captured the original, crafty, "serious" nature of Delgado's Master, since. And we won't even talk about Eric fucking Roberts...
