As a mega Dr who fan since childhood I was really amused by the appearance of the professor and his "telegraph" box in Marleybone. I thought it was a shame you didn't get to interact with him until much later (sorry for the spoiler) Recently I thought, how cool would it be to take a trip with him in the telegraph box. This could all be a tied in with the introduction of a new world.
Instead of just being given a spiral key to the new world we would have to travel with the Professor to find in some area of time and space and once we'd discovered it (after a few battles of course!) the Prof could return us to Marleybone.
