Doctor Who Spoiler Free Preview For The Zygon Inversion
The stakes were certainly raised high in last Saturday's The Zygon Invasion, but with all the scene setting and character moments in place, the concluding part, The Zygon Inversion is given room to breathe, delving deeper into the psychological nature of this tale.
While not quite the global-trotting affair of last week, this time it is a much urban thriller with a Zygon loose on the streets of London and the Doctor fleeing British police who may or may not be the enemy in disguise. But it doesn't lose anything for it; in fact the second half of this story is better than the first.
Peter Harness and Steven Moffat share scripting duties and the dialogue is perfection. This is a particular speech from Peter Capaldi that is so emotionally wrought, so captivating it is sure to make even those who doubted him as the Doctor a fan. But don't worry, there is plenty of humour too.
It also cleverly gets around the seemingly impossible situation the cliffhangers left our characters in last Saturday without the audience feeling cheated. And after the last few weeks have put Clara to the side in the favour of Ashildir and the Doctor, this week Jenna Coleman is back in force, delivering two great performances as the good Clara and evil Clara-clone, the Zygon Bonnie. It will certainly make you less prepared to see her go at the end of series.
Overall, this might emerge as the best episode of series nine yet and against what's come before, that's some stiff competition.
