Yeaaah, the thought of the main companion not falling in love with The Doctor is awesome.

C'mon, there was Rose, Martha and Cap'n Jack, along with people like Madame de Pompadour. Aaand that's just the modern stuff! Although I don't mind some of it, it does get a biiiit excessive. Although Martha seems happily paired off with Tom (hints in Torchwood) and stuff, but seeing as they're coming back and bumping into each other... could get very interesting.
I'm
still apprehensive about Catherine Tate, butttt I won't knock her just yet as I did admittedly enjoy the Christmas ep.
