A beam of sunlight works it way through the window onto the new taur.
It falls onto the human part, waking him up. Stretching out he hits one of the dogs heads.
The dog wakes up and tries to run away.
Jon finds his lower body moving without his control and he tries to fight back. Before too long the room is trashed and the other head has awoken and is conflicting as well.
Finally Jon speaks "What is going on?"
"It appear we are sharing the body" says the dog on the left.
"That will make going on a date hard" says the dog on the right.
