The latest episodes of FX and Hulu's "The Shards" delve deeper into the mystery surrounding new student Robert Mallory (Homer Gere) and his potential connection to the serial killer known as the Trawler. Narrator Bret (Igby Rigney) has fixated on Robert, suspecting him of being the Trawler due to his arrival in town coinciding with the killings and his penchant for deception.
Bret's suspicions are fueled by Robert's unsettling behavior, including inappropriate comments about a mutual crush, Susan (Kaia Gerber), an argument preceding the disappearance of Matt Kellner, and sightings near a secluded house. Episode 4, titled "Robert's Party," depicts a gathering hosted by Susan to integrate Robert into the social scene. During the party, it is revealed that Robert avoids alcohol due to medication and that his mother died in a mysterious accident, after which he was institutionalized. Rumors also surfaced that Robert was responsible for his mother's death.
Bret seizes on these rumors, confronting Robert with the accusation that he killed his mother. This accusation precipitates Robert's dramatic breakdown. He consumes a large amount of vodka, dances erratically to The Go-Go's, and becomes combative when Thom (Graham Campbell) attempts to intervene. The situation escalates with a physical struggle, a kiss between Robert and Thom, and Robert stripping his clothes before walking barefoot over shattered glass and diving into a pool. Thom and Susan ultimately rescue him, with Susan administering mouth-to-mouth resuscitation.
Homer Gere described the filming of the party scene as a liberating experience, stating, "It was really fun and freeing, I think, as an actor for me to be like doing these insane things in front of a hundred background actors and all the crew and everything."
The interpretation of Robert's actions at the party remains open to debate. One perspective suggests Bret's accusations triggered Robert's inherent violent tendencies, confirming him as the Trawler. An alternative view posits that Bret's comment about his mother, combined with Robert's medication and alcohol consumption, led to a psychological escape from his past trauma.
Igby Rigney, playing Bret, cautioned against sympathizing with Robert, stating, "Don’t side with this guy! He comes into our school lying about where he was last year. I just want to say that’s not a good look." Gere, however, defended his character, sarcastically remarking, "Robert is a man of high repute."
Meanwhile, a parallel storyline introduces cult leader Bruce (Gus Halper), a former teacher associated with the "Riders of the Afterlife." Bruce is revealed to be hiding in Susan's bedroom closet and threatens Debbie (Hayes Warner) and Ryan (Daniel Dale) at knifepoint. The cult's symbol was previously found in Matt Kellner's room, suggesting a potential link to the Trawler's crimes. The episode ends with Thom intervening and talking down Bruce, revealing a prior connection between the two characters and raising questions about Thom's potential involvement with the cult.
