I said it then, and I'll say it again in this case - I absolutely not only hope it won't be but seriously doubt it would be an 'aspect of Clara'. Moffat seems to have basically acknowledged that the multiple Clara stuff was a bit of an overcomplicated mess, hence why its been quietly forgotten since with all efforts in series 8 to treat her like any normal companion.”

Maybe Moffett will return to the theme of Clara The Impossible Girl next series but in a less complicated way.
Last Series
Moffett courts controversy. The Doctor goes in search of the Afterlife. Cue outrage and accusations of blasphemy from the Daily Mail.
Why does the Doctor go in search of the Afterlife? Because someone he cares deeply about (Clara) is grieving and in great pain.
This means creating and developing a character for Clara to grieve over - Danny Pink. So that's Clara's story-arc for series 8; balancing the two men in her life. The Doctor is for adventure in time and space and Danny is for love and romance on Planet Earth.
This means The Impossible Girl idea is surplus to requirements.
But a new series needs a new story arc. Rumours abound that the Doctor will be facing great danger from an unknown threat. Now this may just be wild speculation on the part of a Dr Who fan (like the rest of this post.

) but it does seem to fit in with the one piece of dialogue to be overheard during filming in Tenerife.
CLARA: You came here for my help.
MISSY: Because the Doctor is in danger.
The opening 2-part story has the episode titles "The Magician's Apprentice" and "The Witch's Familiar". These sound like supernatural characters, but at the same time it does seem likely both titles will apply to Clara (especially if she gets abducted by Missy).
Meanwhile, Clare Higgins presence in the guest cast suggests the return of The Sisterhood Of Karn and the episode titles suggest they're more likely to encounter Clara than the Doctor.
Maybe the Sisterhood rescue Clara from Missy and send her back to the Doctor to save him from the unknown threat (in the series finale. In the meantime he's a few other adventures from other writers.) Maybe one of the other Clara's that are supposed to be out there will be one of the Sisterhood. Brief scene of Clara meeting Clara in a duel role for Jenna.
And that's why Maisie might well be playing a Clara as well - a rogue Clara. Do it once, do it again in a different way. It would tie in with the Doctor not being able to see Clara properly, allowing Rogue Clara to pass herself off as Good Clara with Good Clara left behind as the cliffhanger ending to The Girl Who Died. it would also explain why Moffett is co-writer of The Girl Who Died. (Although so also would Maisie playing Susan or Maisie playing a young Missy).
This is fun. Where does one apply to be the Doctor's next show-runner?
