Synopsis

Agent Caldwell has been posted to the British Embassy in Moscow and ordered to investigate a rising star of the Communist Party. But Caldwell is a shadow of his former self, plagued by nightmares of the past and misty visions of the future. 

As the Third Doctor enters the fray, human and Zygon plots collide, and Caldwell's visions threaten to endanger the world. Though neither man can remember the other, can the Doctor and Caldwell put a stop to the Zygon Century, once and for all?

Verdict

The Caldwell Restitution was a great episode to conclude the Transformation second series of Zygon Century! We are far from over as a spinoff range that much is clear and that excites me because things are really taking shape now as we venture further into the second half of the century. We're still yet to breach the final quarter but I think that will come with the final boxset, whether that's the next one or beyond is yet to be seen. I think it's great to incorporate the Third Doctor during exile into this century-long plan of the Zygons because he was trapped on the planet so it's no surprise that he would get involved and have knowledge of events here. I was really intrigued by the continuity with Double Agent as we advanced from 1957 there to 1974 here and Agent Caldwell really is a very different man. I think it's fascinating for the Third Doctor to acknowledge the parallel timeline of the ongoing Second Doctor Adventures because that's not the true article, but memories seeped through which in of itself is pretty interesting as a concept! The flashbacks to events on the island were helpful and it's just strange to think that the Third Doctor remembers things that didn't technically happen to him. Of course, I have no idea how the parallel timeline of the Second Doctor will conclude, but I guess it might merge into The War Games and things are semi-retained? Caldwell was clearly troubled in the episode and that stems back all the way to 1957 and what he experienced there. The irony of he and the Doctor having met before but neither remembering the other was good stuff and perhaps not played upon enough in my opinion! It's a pretty unique situation. I just love the idea of a Third Doctor story with the Zygons because it predates Terror of the Zygons which actually isn't a million miles off these events timeline wise. Might they end up being included as part of the century-long Zygon plan? That would be impressive if so! I just love merging eras and that kind of thing so the Zygons encountering this Doctor is good fun for me. Tim Treloar was great again in bringing the Third Doctor back to life and I'm surprised that we only had a Russian member of UNIT. This kind of thing feels ripe for the whole organisation! It was good to venture to Russia in the 1970s as that's a volatile place to be for someone from the West! I love branching off to different countries though and particularly visiting the Soviets definitely seems to give the Doctor less authority and even presence. The way he snuck up on Caldwell though as he was tracking Kovalenko was pretty humorous and far from inconspicuous! Fahrag emerging as the Zygon leading things here was good and the effort at taking over the Doctor's mind was impressive, but he obviously evaded being fully impacted. Breaking the hold they had on Caldwell was good too and that just made his death all the more powerful. I didn't see that coming I must admit so it definitely added to the threat the Zygons pose. I also really enjoyed how they likened the Doctor to themselves with how he changed face and their knowledge on him was impressive. The use of mind control was beyond them though and that's where the ending of An Incident in Death Valley comes in with the Master. Ilse Lange showing up in the epilogue confirms that and what a pairing we have! The Master giving the Zygons direction for this plan is a tantalising prospect and I can't wait to hear what direction things go in next as we continue to explore through the century. Overall, a very good episode to conclude a really intriguing and solid series!
