Throughout its first season, The Testaments did an excellent job depicting the various horrors that young women face in Gilead, especially the wealthy teens groomed to be obedient brides for the country’s much older men in power. But for the show’s main characters, including Agnes (Chase Infiniti) and Becka (Mattea Conforti), the brainwashing has started to crack long before it’s time to take their vows. These two are best friends in a place where the very concept of “best friends” is frowned upon. That mini-rebellion brings them even closer, and it’s not long before we realize that Becka has romantic feelings for Agnes—though neither girl has been allowed to mature emotionally enough to really understand what that means. For her part, Agnes thinks her crush on Garth (Brad Alexander), her hunky bodyguard, means she’s in love with him. A rift appears between the besties when Agnes begins spending more time with Daisy (Lucy Halliday), who’s new to Gilead. But things really fracture when Becka, who doesn’t want to get married in the first place, becomes engaged to Garth—who’s been promoted into Gilead’s husband-material ranks only after a starry-eyed Agnes makes a plea on his behalf.

Haven’t had a chance to watch the finale episode yet? We’ll be discussing “Secaterus” specifics, so turn back now. As The Testaments entered its final episodes, both Becka and Agnes saw their carefully plotted lives veer completely off course. When Becka learned her father, Gilead’s resident dentist, had been sexually assaulting his patients—including her beloved Agnes—she acted on the lessons about righteous vengeance that had been drilled into her over the years and stabbed him to death.
