TL;DR – Not a bad episode, but it is worrying when you can already see some handwaving happening.
Disclosure – I paid for the Amazon Prime service that viewed this series.
Warning – Contains scenes that may cause distress.

Citadel Review –
There are many things a good story can do. One of the main functions is that you become so caught up in the narrative that you don’t see many of the contrivances that the filmmakers have to use to get us from start to finish. That suspension of disbelief is critical, especially as you move away from reality. However, if your narrative slips, so then does that shield.
So to set the scene, we saw in The Human Enigma the almost complete destruction of the Citadel spy agency in a targeted massacre worldwide. One of those places was a train driving through the Italian Alps. The Train exploded, and we found out what happened to Mason (Richard Madden) last week. This week we open with Nadia (Priyanka Chopra Jonas) dragging herself out of the lake and trying to warn everyone, but Bernard (Stanley Tucci) implements a backstop protocol instead. She escapes but collapses from her wounds, wakes up with the bullet out of her leg, and is handcuffed to a bed. Now from here, we will be looking at the episode as a whole, so there will be some [SPOILERS] ahead.
