The Doctor had the TARDIS inside the Tesselector, though, so presumably he gave the teenyweeny people a lift home after they let their ship be burnt for him.

And in the Library episode Ten says 'there's only one time I could have told you' (the clip was on last night's Confidential, where they did a montage of River's life in order of her timeline) - I think that may mean she'll be there at 'the fall of the eleventh' where it sounds as though he'll be forced to reveal it.

(And I completely agree about a Trials and Tribbleations version of Silence in the Library, that would be awesome!)
