I don't want to see a River/Doctor or a Rory/Doctor.... or an Amy/Doctor....
Its just wrong! The Doc shouldn't kiss people!
I mean, like Jack/Doc + Rose in S1 was fine and (The Cassandra)Rose kissing Doc in New Earth was fine....but thats it
Oh and 8 kissing Grace *blergh* Totally wrong and Americanisation Ew!
I don't understand - if the Doc kissing people is wrong, then why was the kiss with Rose in S1 fine? The Doctor initiated that one. He also initiated the kiss with what's-her-name in that Titanic in Space Christmas episode.
Anyway, not saying it has to be him that starts it, or even romantic. If she's meeting him for the first time maybe she wants to manipulate him for some reason and tries the hallucinogenic lipstick on him.
He kissed Rose to transfer the Time Vortex into him, which caused his re-generation into 10.
He kisses Astrid 'cause of the way she died, at least that's how I viewed it.
