Because narrative necessity is more important than consistency and clever lies are cool.

Give or take a Christmas special or two, thats basically it.

Its not a huge surprise.

Retrieving Gallifrey from a pocket dimension will not be difficult in and of itself.

In fact, its as simple as flicking a few switches in the TARDIS.

In story terms, it can be as easy or difficult as it needs to be.

Finding it is a challenge that could sustain a series arc, as could what happens next.

What happens when Gallifrey returns?

Its unlikely to have the Time Lords return, and then immediately be destroyed again.

The other options include the destruction of the Daleks.

While they have become synonymous with the show, this also has its drawbacks.

Regular villains are defeated as often as they appear, making it hard to sustain their menace.

No pressure there then.

Or an episode set on Gallifrey that doesnt feature a single member of the High Council.

A Christmas Special at Andred and Leelas house.

Gallifrey is, after all, where the Doctor ran away from.

It isnt set there.

It didnt even mention its name for the first eleven years.

The whole point is that it doesnt settle, it doesnt stand still.

Theres only so much they can indulge in, even if the plot skirts around fifty years of mythology.

The Gallifrey Falls No More storyline is a tricky one to get right.

Imagine multiple slinkies pratfalling down the stairs, looking like theyre going to crash.

Its going to take a lot of skill, and a lot of luck to avoid the latter.

Besides, no two people will see it the same anyway.
