10 Dropped Doctor Who Plot Threads We'll Never Get Answers To

While this plot thread was kicked off in a deleted scene, former showrunner Russell T Davies has said that he considers it a part of the show, and plus, it's just a really interesting idea to think about.

After Rose Tyler helps the Doctor defeat the Daleks in the Series 4 finale, she has to return to her own universe, but this time, she has the Meta-Crisis Doctor (a clone of the Tenth Doctor created in a prior episode) with her.

In the final, broadcast version of this scene, the real Doctor leaves the couple on a beach and flies off, but there's an additional deleted moment where he gives the Meta-Crisis Doctor a piece of the TARDIS and tells him to "grow your own".

As a result, Rose and her knock-off Doctor are in possession of their own TARDIS, meaning that they're probably having their own weird and wonderful adventures in space and time, all within their own parallel universe.

While it's nice to think that Rose and a version of the Tenth Doctor are still out there somewhere, journeying through the cosmos, this plot thread will likely never be revisited, for several reasons.

For one thing, it was started in a deleted scene, but the main sticking point is that it would require David Tennant and Billie Piper to return to the show - not impossible for Doctor Who, sure, but a scenario that seems like a fanboy pipe dream at best.
