I haven't listened to that one, but I have listened to the story following it, Dark Eyes
. Let's just say that it takes the Doctor some time to recover from what you put in the spoilers. The Time Lords force him to go on a mission when he all but attempts suicide by heading to the very end of the universe.

I've mentioned this elsewhere, but my copy of Dark Eyes
is signed by Paul McGann and Nick Briggs (who both wrote the story and voiced the Daleks).
