In the latest episode of The Testaments, a significant deviation from Margaret Atwood's novel occurs when Dr Grove meets his end not by the Handmaids' hands, but by his own daughter Becka's. In the book, Aunt Lydia frames Dr Grove for attempted rape of Aunt Elizabeth, leading to his execution by 70 Handmaids in a Particicution. However, the show speeds up this timeline and introduces a new motive.
Earlier in the season, Dr Grove assaulted Agnes MacKenzie during a dental visit, opening her shirt while she was anaesthetised. When Agnes confided in Daisy, she fabricated a similar assault to expose Grove. This public accusation prompts Becka, Grove's daughter, to confront her father. At dinner, Grove denies touching Daisy, but Becka infers the truth about Agnes.
Later, Becka stabs her father to death while he bathes, then appears covered in blood at Agnes's house, declaring, 'He can't hurt you anymore.' The show reveals Becka's deep love for Agnes, a romantic element absent from the book. This twist cements a queer narrative integral to the adaptation.
After the murder, with help from a silent Martha, Agnes cleans Becka up, and they plan to flee Gilead. Becka professes, 'I would do anything for you,' but Agnes's response remains uncertain as they walk away together, leaving their fate open.
