Gregor completely transforms into a “rager” as he takes charge of the mission, showing a level of aggression and intensity he never displayed before. The term “rager” itself is given new meaning because he channels and uses his rage now to avenge Boots’s death, even though he never relied on negative emotions before. When Howard hesitates to follow his orders, Gregor reveals the secret that he’s a “rager” and threatens to fight Howard, which illustrates a dramatic shift from his earlier reluctance to embrace violence: “‘Okay, but if you try to follow me, I’ll fight you,” said Gregor [to Howard]” (207). Gregor’s threat signals his acceptance of his rager identity: He no longer fears what it makes him, and he achieves his goal of forcing Howard to take Mareth and his bat back to Regalia. The plan narrows under Gregor’s leadership: Only Gregor, Ares, and Twitchtip will venture into the tunnels to kill Bane. The responsibility now rests entirely on Gregor’s shoulders, a task or murder he almost relishes. His character arc reaches a turning point as his motivations shift from self-preservation to vengeance, fueled by his belief that Boots is gone.

Twitchtip’s determination is evident as she guides Gregor’s team through the Labyrinth, but her collapse forces Gregor to make the heartbreaking decision to leave her behind. Twitchtip’s exhaustion highlights the emotional cost of war and thematically foregrounds The Impacts of War, Violence, and Prejudice, demonstrating how even the most loyal allies can be pushed beyond their limits. Her sacrifice shows her commitment to the mission but also emphasizes the harsh reality of the journey. Ares assures Gregor that leaving her behind is necessary, allowing Gregor to continue with their goal. Despite caring deeply for Twitchtip, Gregor understands that completing the task ahead must take priority, as does Twitchtip herself, who doesn’t hold it against Gregor. Still, he worries about her: “And Gregor and Ares left her lying on the tunnel floor. When they came to the place where the tunnel split in three, they paused. Gregor had an image of Twitchtip, lying in the darkness, bleeding to death” (217). This decision marks a key moment in Gregor’s growth as a leader: He must balance compassion with the hard choices required in war. The loss weighs heavily on Gregor, underscoring the emotional toll of their quest. Ultimately, losing Twitchtip strengthens his resolve, adding emotional complexity to both the rat’s tenacious character and the difficulties of their quest.

Gregor’s immense grief over Boots’s presumed death illustrates the depth of sibling bonds. However, he represses his pain because he needs to maintain control during a fast-paced, high-stakes journey. Though he loves Boots and misses her, he can’t afford to break down with so much at stake, so he buries his emotions, reflecting how people often repress grief in order to keep moving forward: “He took a deep breath, pushed Boots out of his mind, and imagined the rats laughing. The ice sealed back over his chest” (218). This emotional suppression takes a toll, and the moment when the baby rat Bane cries out for his mother, reminding Gregor of Boots, shows how deeply his unresolved grief affects him: “The baby [Bane] snuggled closer to him. It was so much like holding Boots. Boots. Why wasn’t he crying about her?” (242). The plot moves quickly, and Gregor doesn’t have the time or space to properly process his feelings until later. When he finally lets himself cry and mourns Boots by smelling her clothes while he’s alone in the museum, it becomes a pivotal moment of healing. His sobbing demonstrates how repressing emotions only delays the inevitable need for release. Gregor’s breakdown makes him more relatable, teaching young readers that it’s okay to feel and let go of bottled-up emotions, especially after loss.

The final revelation that the prophecy’s mention of “the baby” refers to Bane rather than Boots shifts the entire narrative around the prophecy and challenges the Prophecies Shaping Actions theme. The misinterpretation of the prophecy alters the stakes of Gregor’s mission and forces him to confront the possibility that Boots could still be alive. However, Gregor’s grief and doubt cloud his hopes, leaving him to wrestle with the reality of his sister’s presumed death. The trial scene following this twist intensifies the conflict, providing an unexpected challenge and increasing the tension as Gregor must defend his moral actions by highlighting their past battles and sacrifices. However, during the trial, Nerissa steps in to support Gregor by explaining that his actions upheld the correct interpretation of the prophecy (and Vikus backs her up). This marks a turning point in the novel and thematically resolves The Ethical Dilemma of the Empathetic Hero. The truth illuminates Gregor’s empathetic decision to not kill the baby Bane and reveres him for fulfilling the prophecy. The trial gives Gregor his freedom, affirming the group’s commitment to winning the war without becoming merciless killers.

Following this resolution, Gregor’s reunion with Boots takes him from the immense grief of believing his sister was lost forever to overwhelming joy and relief when she reappears, having survived her ordeal. This highlights their unbreakable bond and familial love: “‘Hi, you,’ Gregor said [back], thinking he would never let go of her” (294). His reaction reflects how deeply their separation and his belief that she was gone affected him. Given the trial’s success, Gregor’s freedom to leave with his sister is a fitting culmination, rewarding him as the hero. Despite the struggles, losses, and misunderstandings, the siblings are together again, offering a bittersweet but hopeful conclusion to the narrative whereby they can return home alive and safe.
