So I'm going to jump right into this look back at last night's episode after the spoiler caution.
Here comes the recap/ review thingy in 5
In case you need a refresher with what's up with the Zygons, the episode opens with recap of events from The Day of the Doctor with the 10th and 11th Doctors along with the War Doctor brokering a peace between humans and Zygons, We also get a helpful video message from Osgood...and Osgood explaining the whole peace deal arrangement and how bad it would be if it fell apart.
And then it falls apart.
The Doctor meets with UNIT where Kate Stewart who was once all about "my father taught me science leads" but is now willing to bomb the bejeezus out of some Zygons. But the Doctor is in the "anti-bombing the bejeezus out of anybody" camp. So here's the deal:
- The Doctor heads off to join up with a UNIT force in Tzrksrxstan where Zygons are holding our remaining Osgood (after the other Osgood got zapped by Missy last season). A whole bunch of UNIT soldiers with guns gets taken down by Zygons who look like their mothers. UNIT gets in some missile strikes on Trzgxkrkstan but not before the Doctor rescues Osgood and captures a Zygon. Well, score one for the Doctor but...all is not what it seems.
- Kate Stewart is off to Truth Or Consequences, New Mexico all by herself. (Don't worry, she has a little gun. You should see it, it's so adorable.) Kate finds the town deserted save for one lone female police officer who tells the tale of town over run by....British people. Oh, and who later turned into alien reptile creatures and killed everybody. So it looks like Kate is on to something but... all is not what it seems.
- Clara Oswald and a UNIT operative named Jac are holding down the fort in London looking into weird stuff going down with elevators....excuse me, this is in the U.K....going down in LIFTS. (Why can't the English speak English?) This weird stuff which leads to a really strange underground Zygon base where (say it with me) all is not what it seems.
Doctor Who takes on a rather big and very much real world problem, tensions over immigrants. Tensions within an immigrant community between assimilating into another culture or holding fast to their own. Tensions among natives torn between accepting newcomers and being on guard against those who may cause trouble for all. And tensions between immigrants and natives.
Alas, poor Clara Oswald gets Zygonized. To be honest, Clara being a Zygon for most of the episode was not a big surprise. But wow, Jenna Coleman does a great slow fade from innocent Clara to not so innocent Zygon duplicate named Bonnie.
And Kate Stewart gets replaced by a Zygon...again. Except...I don't think so. Yeah, I'm thinking Kate overcame the Zygon in New Mexico and is pretending to be Zygonized.
