Kumail Nanjiani‘s guest appearance as Paladin Xander Harkness in Fallout Season 2 is one of the most talked-about moments, and one of the most divisive among fans. The actor made a powerful debut in the season’s second episode only for his character to be killed off in the very next installment, leaving many viewers feeling the show wasted a perfect sci-fi actor and an intriguing new character. This quick exit has sparked debate about the season’s storytelling choices and its use of major guest stars.
Who Was Paladin Xander Harkness and Why Did He Matter?
In Episode 2, “The Golden Rule,” the Brotherhood of Steel is gathered at Area 51. Elder Quintus is trying to convince other Brotherhood chapters to rise up against a powerful, overseeing faction known as The Commonwealth. To mark the occasion, Maximus is forced into gladiatorial combat. Just as he seemingly defeats his opponent, a new figure arrives dramatically.
Kumail Nanjiani’s character enters, announcing himself with cool authority. “Sorry to interrupt. Paladin Harkness. Liaison from The Commonwealth. I understand we’re discussing a Civil War? I must have not gotten my invitation,” he says. His entrance immediately shifts the power dynamics in the room. Paladin Xander Harkness was a representative from the Commonwealth Brotherhood, a chapter that controls the Eastern seaboard of the former United States, centered in Boston. His arrival signaled that the local Brotherhood’s plans had attracted attention from a much larger, more powerful authority.
For fans of the games, the mention of The Commonwealth was a major moment, as it is the primary setting of Fallout 4. However, the show presents it as a region firmly under the control of this advanced Brotherhood faction. Harkness himself was a new character created for the show, having only appeared briefly before in a tie-in for the mobile game Fallout Shelter. His rank of Paladin places him below an Elder like Quintus, but his affiliation with the powerful Commonwealth chapter gave him significant sway.
The Sudden End of a Promising Character
The intrigue around Harkness was short-lived. In Episode 3, “The Profligate,” the character meets a sudden end. The episode sees Maximus on a messy personal journey, caught between the manipulations of Elder Quintus and the seductive charm of Harkness. Kumail Nanjiani played the Paladin with what reviewers called a “maverick charm” and “Han Solo-schtick,” convincingly buttering up Maximus with tales of how he’d be leadership material in the Commonwealth.
This manipulation peaks when Harkness reveals his true goal: he wants to take the Cold Fusion technology—the season’s powerful MacGuffin—for the Commonwealth. The situation escalates when Harkness threatens a group of ghoul children. In a defining moment for Maximus’s character, he makes a rare independent decision. To protect the children, he kills Paladin Harkness. As one reviewer put it, “Killing off Kumail Nanjiani’s Paladin Harkness just a single episode after he was introduced is a bold move”.
Fan and Critical Reaction: A “Wasted” Opportunity?
The swift departure of Nanjiani’s character has become a focal point for discussion about the season. Many critics and fans feel the show missed a significant opportunity. Reviews note that Kumail Nanjiani, known for roles in Silicon Valley, The Big Sick, and Marvel’s Eternals, seemed to relish playing a “cocky heavy”. One review stated Nanjiani was “having the time of his life” in the role, which made his quick exit even more disappointing for some viewers.
The criticism centers on the idea that a talented actor with proven sci-fi and comedy chops was brought in for what amounted to an extended cameo. Instead of allowing the conflict between the local Brotherhood and the Commonwealth to simmer or develop into a larger storyline for the season, the show resolved it almost immediately through Harkness’s death. This choice has led some to argue that the potential for a fascinating power struggle was sacrificed, and a compelling character was wasted.
This sentiment ties into broader discussions about the season’s pacing. Some reviews of the first six episodes suggest Season 2 has a slower, more deliberate pace focused on setting up future conflicts, with one review noting “not much wholly new or exciting happens” in the early episodes. In this context, Harkness’s abrupt storyline can feel like a narrative detour rather than a meaningful plot development.
How Harkness’s Death Shapes Maximus and the Brotherhood
While some see the character as wasted, the story choice serves a clear purpose for Maximus’s character arc. Aaron Moten’s performance as the conflicted Brotherhood squire has been highlighted as a strength of the season. Throughout the episode, Maximus is shown to be weak-willed and easily influenced, first by Quintus and then by Harkness’s flattery.
His decision to kill Harkness is presented as a transformative moment. It is the first major choice he makes entirely on his own, motivated by his own moral compass—to protect innocent ghoul children—rather than the dogma of the Brotherhood. This act of defiance against both the invading Commonwealth and the expectations of his own elders is a key step in Maximus’s journey toward defining his own path.
The death also intensifies the brewing conflict. It effectively starts the war that was being discussed. By killing a representative of the powerful Commonwealth chapter, Maximus has potentially drawn the ire of a massive external enemy onto his already-fractured Brotherhood. The consequences of this action will likely ripple through the rest of the season.

The Bigger Picture: Guest Stars and Season 2’s Expanding World
Kumail Nanjiani was not the only major name to join the wasteland for Season 2. The season features notable guest spots from Justin Theroux as the pre-war tech mogul Robert House and Macaulay Culkin as a commander in Caesar’s Legion. Theroux’s role, in particular, has been praised, with critics calling his performance “mesmerizing” and noting his intense chemistry with Walton Goggins’ Cooper Howard.
The handling of these guest roles differs. While Harkness’s story is brief, Theroux’s Robert House is woven deeper into the flashback narrative and the overarching mystery of the season. The contrast has fueled the debate over whether the show is effectively using its high-profile talent to build its world or simply creating shocking moments.
The second season of Fallout continues the story of Lucy and the Ghoul tracking her father, Hank, toward New Vegas, while Maximus deals with the fallout within the Brotherhood. New episodes release weekly on Wednesdays on Prime Video, with the season finale scheduled for February 4, 2026. Whether Paladin Harkness’s brief role will have lasting significance or remain a point of contention is a question only the remaining episodes can answer.
