The Expanse Season 3 Episode 2

In previous reviews for The Expanse, the show has been praised for its use of gravity as a character in that the actual science behind g-forces, whether null or boosted by acceleration, informs the overall story to great effect. Upon watching “IFF,” it seems more accurate to say that gravity is a catalyst for conflict or a focus for action, and the episode excelled in this regard. The title, “IFF,” also brilliantly addresses the compelling theme of identifying of friend or foe, whether among Holden’s arguing crew, between the Pinus Contorta and the Razorback, or even with the new character played by Elizabeth Mitchell, who challenges Errinwright for the attention of the UN leader at a crucial time.

Mitchell is, in fact, perfectly cast as Anna Volovodov, or Pastor Anna as readers of the James S.A. Corey novels know her, even though her appearance, character, and history appear to be quite different here. Mitchell’s ability to smile with equal amounts endearment and menace and to combine wide-eyed disbelief with a strength of resolve are perfect for this role in which Anna must place a moral and religious framework around the UN war and the origins of the protomolecule. The softer side she shows her wife and daughter and the hard edge revealed by her past as the Secretary General’s speechwriter create a complex character from the very start.

Plus it’s great to see Errinwright squirm now that someone else has the ear of Esteban Sorrento-Gillis. When Anna says that there are things in the universe bigger than them, it not only refers to the God of her belief system that the politicians in the room don’t share and in fact ridicule; it also is a nod to the alien force behind the protomolecule, which Errinwright seeks to control but which Jules-Pierre Mao actively seeks to prevent him from acquiring. Errinwright as warmonger is a more concrete antagonist than The Expanse has had in the past, and his discomfort and inevitable downfall is fun to observe.
