Actually, I was troubled for days by a story involving a Ten and another David Tennant character and Martha.
Hey, wait a minute, I'm not catholic!
I do fancy Billie Piper a bit, so that's probably one reason why Rose works for me. But it's her loyalty to the Doctor that makes her attractive (and also, granted, really annoying sometimes), so shipping her with anyone else just doesne work for me. (and yes, Rose/Pete, beyond wrong)
I like some of the more straightforward Supernatural/Who crossovers. I've never done a crossover... hmm...
Being Human/Doctor Who anyone?
BTW, how many series is Supernatural now? Should I try and get hold of a cheapo boxset of the first series? Or is there another way to watch? I have no idea what channel it's on.
