Episode 5 of Re:Zero Season 4 splits its focus between the tower's library-a repository of everyone's memories, searchable only by knowing the person-and a flashback to Typhon's childhood, where her Authority of Pride killed anyone who felt guilt, making her a tragic mass murderer unaware of her own wrongdoing.
Episode 6 of Re:ZERO -Starting Life in Another World- Season 4 focuses on combat and character development as the party faces Reid, the original Sword Saint. The episode features two rounds of Reid versus Julius and one round of Reid versus Emilia, with the animation serving as eye candy for the action quota. The central dilemma is that every member of the party must defeat Reid to proceed to the next floor of the tower, including Subaru, Anastasia, Meili, Ram, Rem, and Julius. However, Reid is willing to adjust the rules, suggesting that overcoming him requires intellect rather than sheer strength. The battles also advance character arcs: Emilia's sheltered nature causes her to not register Reid's sexual harassment, surprising him and allowing her a clean hit. Julius's fight explores his lifelong status as second best compared to Reinhard, and his pride in being chosen by Anastasia-a memory now only he retains. The episode draws parallels to Subaru and Julius's fight from the first season, with Julius emulating Subaru's earlier absurd proclamation and willingness to accept consequences. A staircase scene metaphorically depicts Subaru supporting Julius rather than carrying him, acknowledging Julius's need to walk his own path with help, similar to how Rem once helped Subaru.
Animehunch examines the long-running theory that Natsuki Subaru is the Sage Flugel, citing evidence from the current season of Re:Zero. Shaula identifies Subaru by scent and speech patterns, and a tree Flugel planted 400 years ago bears a message in Japanese kanji that reads "Flugel was here." Subaru had the same urge to carve his name on it.
