Lis - Benton - finished
The Doctor was, frankly, hiding in his TARDIS. He'd run away from what had happened with John and left someone else to fix it. He'd ended up here - and then been confronted with his own possible future and it had scared him. He spent several hours just walking the corridors of his TARDIS, because if he couldn't run, at least he could walk.
He ended up, as always, back in the console room. Still pacing.
