I've always been rather sure that Nine didn't suck all the Vortex stuff or what ever it was out of Rose with that kiss! That some Bad Wolf was still there--I mean, look at that reference by the Werewolf in Tooth and Claw. And Rose remembers some stuff in Doomsday. I tried last year to write a fic about this but RL got in the way. If Bad Wolf doesn't save the day, either Donna or the TARDIS will.
