Phillip and Elizabeth both show signs of mental strain.
This is a very strong episode that brilliantly shows the mental state of the lead characters. I can't say that I found it enjoyable, but appreciate that it is high quality filmmaking.
The plot covers a lot of ground, shifting characters and events forward considerably, which is appropriate considering the pressure and focus of the past few episodes. It has some interesting themes, particularly around the choices individuals make in life.
There are quite a few memorable scenes that are very well filmed and edited. The opening sequence is quite haunting and one musical montage towards the end is excellent.
All performances are superb, with Keri Russell, Holly Taylor, Matthew Rhys and Frank Langella doing great work.
For me it's a 9.5/10, but I round upwards.
