Doctor Who: 10 Dropped Plot Threads We'll Never Get The Answer To
Doctor Who... knows how these plots were supposed to end.
We're right on the cusp of a brand new age for Doctor Who. The upcoming season 11 will see Jodie Whittaker steer the TARDIS in a fresh direction as the Thirteenth Doctor, alongside her squad of companions Ryan, Yaz and Graham (Tosin Cole, Mandip Gill and Bradley Walsh, respectively). New showrunner Chris Chibnall has been keen to emphasise that this is basically the 2005 reboot all over again and is hoping to wipe the slate clean. Even the Daleks supposedly won't appear.
While this is good news, it does mean that many of those questions we had by the end of Steven Moffat's lengthy era on the show, as well as those leftover from the Russell T. Davies years, will never be answered. Both previous showrunners introduced some major concepts during their tenures on the series - but they both can also be accused of dropping the ball sometimes when it came to wrapping the narrative up.
So, just before we venture into the era of the Thirteenth Doctor, let's first spend a moment looking behind us as we remember some of those perplexing Doctor Who plots that apparently got lost in time.
10. What Happened To Those Dalek/Time Lord Hybrids?
2015's season 9 opened with a bang with thrilling two-parter 'The Magician's Apprentice/The Witch's Familiar.' It featured the return of Missy, Skaro and Davros himself - exploring his childhood and adding new layers to the Dalek-creating tyrant.
The climax still left us scratching our heads, however. It's ultimately revealed that Davros' dying act was a ruse to get the Doctor to share some regeneration energy with him. The evil scientist siphons this off to his babies and so creates Dalek/Time Lord hybrids: basically Daleks with the power to regenerate.
There's a fatal flaw, though, as Davros' scheme also awoke the abandoned Dalek mutants in Skaro's sewers who rose up and attacked those with shells. The Doctor seems to treat this as the end of it but he couldn't have been paying close enough attention.
In shots of the exterior of the city, we can clearly see many Daleks patrolling the skies. Surely these weren't affected by the sewer mutants on the ground, which means they must still be out there somewhere.
