when the 9th Doctor took the energy from the time vortex out of Rose and put it back into the core of the TARDIS? While the energy was inside of Rose, it took over her body and called itself Bad Wolf. What if this regeneration was taken over by the bad wolf energy when he poured the extra regeneration energy into the time vortex? What if this is how Bad Wolf gets released into the universe? What if they got some writers that were good enough to make me watch this show again? At this point, Doctor Who cares?
