Garth Is ‘The Testaments’ Most Dangerous Wild Card — Everything That Happens to Gilead’s Secret Rebel

‘The Testaments’ has subtly crafted one of Hulu’s most intriguing new characters from a figure who barely makes an impact in Margaret Atwood’s original novel. Garth, the young Guardian assigned to the MacKenzie household, is becoming the emotional core of the show’s resistance narrative, and the deeper you delve into his storyline, the more unsettling his circumstances appear.

Portrayed by Brad Alexander, Garth enters the series as a seemingly loyal component of Gilead’s system. He serves as a young Guardian for the MacKenzie family while secretly acting as a deep-cover agent for the Mayday resistance group and functioning as Daisy’s handler. This tension between outward compliance and inner rebellion creates an electric dynamic in every scene he shares with Agnes and Daisy.

The series quickly establishes that Garth is not who he seems. When Daisy presents him with a map of the school she has created for Mayday, Garth feigns ignorance the moment other girls arrive, showcasing how meticulously he maintains his cover even in critical situations. His loyalty to the rebellion is unwavering, yet the show highlights the precariousness of his position.

Brad Alexander has mentioned that the specifics of how Garth initially joined Mayday remain somewhat ambiguous within the story, but two significant factors motivated his shift toward the resistance. The first is a moral awakening. Alexander explains that Garth has witnessed firsthand how the personalities of these girls are being suppressed to fit into Gilead’s patriarchal framework, leading him to a profound moral realization about the regime’s wrongdoings.

The second motivation is more personal. Garth’s father was a prominent Commander and fighter in Gilead until what the show refers to as the Boston moment, during which he was injured. This injury has fostered a resentment in Garth that the series has only begun to explore. Alexander notes that Garth harbors anger towards the system that raised him.

One of the most notable creative decisions made by the show involves Garth’s background. In Margaret Atwood’s novel, Garth resides in Canada rather than within Gilead, making his television portrayal almost entirely distinct. The series places him directly within the regime’s borders, significantly raising the stakes.

Alexander envisions Garth as a native of Gilead who has been indoctrinated by its propaganda throughout his life, with little recollection of what existed before. This reimagining transforms the character from an outsider operative into something more unsettling—a man shaped by the very system he seeks to dismantle.

Alexander has remarked that reading the original novel aided in shaping his interpretation of Garth, even though the character is largely redefined. What remains consistent is Garth’s confusion and good intentions, as he desires the best for everyone despite being uncertain about how to achieve it.

The pivotal moment in Garth’s season-one journey occurs in episode five. Agnes and her fellow Green girls attend a ball where they are showcased before Commanders seeking young wives, and Agnes becomes particularly intrigued by Garth after learning he is set to be promoted to Commander soon. A dance between them intensifies her feelings, which viewers can clearly perceive, even as Garth grapples with understanding his own emotions.

Alexander explains that Garth’s understanding of romantic love is virtually nonexistent; he doesn’t truly grasp what it is, and he confronts these feelings for the first time, unaware of what is happening within himself. The show presents this as genuinely poignant rather than merely convenient, as Garth’s emotional naivety is a direct consequence of growing up in Gilead.

Alexander acknowledges that Garth might be somewhat naive regarding the implications of his new Commander status. While he views it as a chance to further Mayday’s objectives more aggressively, he may not fully comprehend that it also places him in a more dangerous position, where the insider information he acquires could become a liability. The promotion is less a victory and more a countdown.

By episode seven, Garth emerges as a potential romantic interest for Becka instead of Agnes, creating an emotionally complex situation for all involved. Agnes is conflicted about her feelings for someone who might be paired with her close friend, while Becka herself has no desire for marriage. Given Garth’s secret collaboration with Mayday, there is a quiet reassurance in the notion that he wouldn’t harm Becka if they were to be matched.

In episode seven, Garth also confiscates Daisy’s vintage radio during a handoff, coldly informing her that it is contraband and that she will have no use for it where she is headed. This chilling moment underscores how convincingly he can portray loyalty to the regime when necessary. Alexander has likened Garth to Nick Blaine from ‘The Handmaid’s Tale’, noting that both characters embody men grappling with their roles within Gilead’s patriarchy while confronting the harsh reality that the women around them are being oppressed. Whether Garth’s dual existence can withstand the pressure long enough to impact the resistance is the central question propelling his storyline forward, and it’s certainly worth sharing your thoughts on the direction his arc might take before the season finale.
