Beatrice’s Dramatic Return in Re:ZERO Season 3 Episode 15
Plot Overview
The episode opens with intense action featuring Lye Batenkaitos, the Sin Archbishop of Gluttony, battling Otto Suwen and Felt’s allies. Despite their numerical superiority, Otto and his team struggled to gain the upper hand against Lye, who arrogantly claimed inferiority to Roy Alphard. The scene quickly shifts to Roy’s confrontation with Julius Euclius and Ricardo Welkin, where it appears he anticipates their every move.
In a pivotal moment, Julius employs an unexpected tactic that surprises Roy, leading to a counterattack using a devastating technique called “Eclipse,”which he claimed had coincided with the demise of 88 others before him. As Julius suffers injury, Roy diverts his focus to Ricardo, conjuring two dragons from water magic. When questioned about his identity, Roy mockingly identifies as “a humble, nameless mage.” However, he hints at a deeper connection by referencing their shared impoverished past, stirring an emotional response in Julius.

Flashbacks reveal a younger Julius caring for a sickly individual, potentially a sibling, enhancing the tension of their confrontation. Back in the present, Roy’s insinuations about their history provoke Julius to frustration; after a moment of hesitation, Julius attacks fiercely. Nevertheless, Roy evades each strike effortlessly.
During this combat, Julius prepares a climactic assault, fueled by resentment towards Roy’s past choices. The focus then transitions to Aldebaran’s duel with Capella, who provocatively questions how long she must endure his attempts on her life. Despite Aldebaran’s declarations of bravery, Capella accepts the impending strike, framing it as an act of love.
In a darkly foreboding tone, Aldebaran suggests that “dying hurts, and is scary… especially the first time,” hinting at his own past experiences. Unmoved, Capella transforms into a dragon, compelling Aldebaran to initiate a trap designed to collapse the sewers onto her.
While the sewer collapses, Capella maintains her perspective of their confrontation as a romantic entanglement. As chunks of debris fall, Aldebaran manages to escape to the nearby waterways, where he comes across Anastasia Hoshin. Uncertainty about their safety leads to a brief confrontation when Aldebaran accuses Anastasia of deceit regarding her magical abilities. Felix Argyle intervenes to quell the tension, forcing Aldebaran to lower his weapon.
Capella, in a moment of transformation, disperses into a swarm of rats before reforming as a human. However, she quickly decides to withdraw from the battle, claiming to have achieved her objectives. Anastasia accuses Capella of merely acting on divine instructions, leading to tension among the group as they grapple with the implications of Capella’s actions.
As Otto continues his resistance against Lye, he learns that Lye possesses the uncanny ability to absorb the experiences and memories of his victims. Otto realizes that Lye’s power derives from countless past encounters, complicating their struggle. Although Otto employs explosives against Lye, they fail to yield significant impact, merely tearing Lye’s garment and revealing a grotesque physique.
The climax of the episode features Beatrice arriving just in time to rescue Otto from Lye’s impending grasp. The episode concludes on a cliffhanger with Lye using Rem’s memories to confront Beatrice, suggesting her significance in the ongoing turmoil.
Closing Thoughts
With gripping battles against the Sin Archbishops of Gluttony still in motion as the season nears its finale, viewer anticipation is high. It’s probable that the focus will remain on the confrontation between Beatrice and Otto against Lye, while the resolution of Julius and Ricardo’s battle may unfold in the season’s closing moments. Fans can also look forward to hints about the direction of season 4, as the abundance of source material continues to expand under White Fox’s direction.
