The Oath

One of Elizabeth's sources supplies information about US missile defence and sets up a meeting with a high level military commander.

I enjoyed this one for the way increases the level of excitement to set up the series 1 finale and how it brings some of the show's themes to the forefront.

Trust and loyalty have been a big part of the series and in the episode we see pretty much how every character behaves in a number of situations associated with both. As an audience we know all these characters secrets and it makes the plot both compelling and ironic at times. I can't say much more without spoilers only that this one feels like it starting to edge the overarching series narrative forward a bit more than other episodes have done.

All performances are excellent, whilst the cinematography and editing keeps things very intriguing throughout.

For me it's an 8.5/10 so I round upwards.
