Centers cannot hold, as a coup occurs at the military institution, suspicions arise in Cosima’s new relationship, Helena makes a sandwich of Pupok, the Hendrixes ratchet up their business dealings, and Paul, among others, is dead.

The episode also confirms that the Castor Clone Glitch infects their sexual partners, and Rachel knows something about the missing code.

High Points

This episode features strong moments for most of the key characters, where each faced significant risks, with their actions having real consequences. Unsurprisingly, it appears that some of those characters didn’t survive the episode.

Low Point

Individually, the developments and elements work. However, they don’t all mesh, leaving a somewhat chaotic episode.

The Scores:

Originality: 4/6

Effects: 6/6

Story: 5/6 This episode features memorable moments, but it doesn’t feel entirely coherent. What it does do, however, is answer several lingering questions.

Felix works with the Hendrixes next week; maybe we’ll finally see them return to the fold, perhaps financing Clone Club.

Acting: 6/6 The acting remains exceptional, with Dylan Bruce as Paul Dierdan stepping up for his finest moments in the series. It’s difficult to say which Tatiana Maslany character stands out most this week, but the script asks much of Sarah and Helena, and she delivers.

Emotional Response: 6/6 One thing about “Certain Agony”: it leaves us wanting to know where on earth the next episode will go.

Production: 6/6

Overall: 5/6 I’m not certain what metaphoric significance we might find in a glitch/virus that attacks men’s brains and women’s ovaries, but at least the show makes us ponder its greater significance.

In total, “Certain Agony on the Battlefield” receives 38/42
