The Curator and his TARDIS

Not only is this scene heart-warming, funny and tender--and brilliantly acted by both Smith and Baker--it significantly re-sets the old show's course. The Doctor is no longer running from, he is running to--to the discovery and possible rescue of his lost people.

And, judging from the roundels along the wall of the Museum, there is at least one possible source of help in an emergency.

After all, to steal a tag-line from another franchise, the best never rest.
