Believing for years that his home planet of Gallifrey was destroyed in the Last Great Time War, the Doctor was amazed to discover a couple of years ago that it actually still exists but frozen in its own ‘pocket universe’.



He couldn’t be more grateful that Gallifrey is still around because, after the traumatising death of his companion Clara Oswald (Jenna Coleman), home is where he wants to be more than anywhere else, so he can nurse his deep emotional wounds.



In this week’s series finale, Hell Bent, the Doctor has finally arrived on Gallifrey, and he’s in a very angry mood, wanting to find a way to bring Clara back – but of course that’s something he can’t do.



The Doctor is still in a foul mood as he faces his fellow Time Lords – led by The President (Donald Sumpter) – as well as Ohila, the High Priestess of the Sisterhood of Karn (Clare Higgins).



He also wants to find out more about the mysterious Hybrid, a creature that’s been a legend throughout Time Lord history and who he battled in the weird world he was trapped in before he got to Gallifrey.



The adventure also sees him come across a dalek and cyberman and ends with an almighty struggle that takes The Doctor to the end of time…
