Pluto2 wrote: In fact, every now and then the New Series writers add throwaway lines referencing the Shalka Ninth Doctor's backstory. Time of the Doctor has the android boyfriend line, and Hell Bent has this: [snip] The validity of Shalka has nothing to do with continuity. Despite this discussion being opened for continuity-related matters, we're past that point.

What matters is whether it was "intended to take place [within] the DWU". Because of the unique circumstances of its production, this phrase can be interpreted either way.

It should be noted, of course, that the DWU is not a single progression of events. Shalka can easily take place within that big ball of wibbly-wobbly, timey-wimey stuff that is the DWU, even if not within the Doctor's "main" timeline.
