... he is shot. Indeed, the target for assassination had changed... why kill the princess when you can kill the future Emperor? The guests scatter and the temple bursts into confusion as soldiers and assassins start battling all around them. Py holds her betrothed and dying Doctor in her arms. There is a flash of golden light... and where her Doctor once lay, there is now Doctor number 6: Chris Addison!
Much to Py's dismay, this new Doctor isn't so much dashing and heroic and more scruffy and distracted. The most inventive and brilliant incarnation so far, 6 can't stop working or tinkering in the Tardis, fascinated by any piece of alien technology that passes his way. Thus he doesn't bother with a proper outfit, and tends to wander around in well-worn overalls or working jumpsuits. He never travels without a full bag or belt of tools and rarely scrubs up. Sometimes absent-minded, sometimes bitingly witty, Doctor number 6 is not what Princess Py wanted in a partner. Disgusted by all forms of manual labour, she can't stand the new technician-Doctor and the two often bicker.
Either way, there's still a load of people who want her dead, and he's still the best man to protect her.
