Attack on Titan Complete Watch Guide: Exactly Where Season 2 Fits In
The thematic climax arrives in Episode 31, "Warrior," delivering one of the most unorthodox betrayals in modern television. Rather than using grand speeches, Reiner Braun confesses his true identity during a casual background conversation atop Wall Rose:
"Five years ago, we breached the wall and began our attack on humanity. I'm the Armored Titan, and he's the Colossal Titan."
This jarring reveal stems from Reiner’s fracturing psyche, broken by the irreconcilable divide between his soldier persona on Paradis and his role as a warrior for an unseen foreign power. When Eren attempts to dismiss the claim as combat fatigue, Bertholdt’s silence forces the issue. Mikasa Ackerman strikes without hesitation, triggering lightning bolts that illuminate the rain-swept wall.
Wit Studio’s animation during the subsequent brawl between Eren’s Attack Titan and Reiner’s Armored Titan remains a franchise benchmark. Eren relies on Annie Leonhart's mixed martial arts techniques, applying joint locks to shatter Reiner’s defensive plates. Concurrently, Ymir's narrative comes to the forefront. At Utgard Castle, she reveals her possession of the Jaw Titan to protect Historia Reiss. Season 2 traces Ymir's tragic backstory: sixty years spent wandering the wasteland outside the walls as a pure Titan after being deified and betrayed by an Eldian cult, before accidentally consuming Marcel Galliard to regain her human form.
