Attack on Titan Episode 9: Whereabouts of His Left Arm: The Struggle for Trost, Part 5

The episode begins with the grim history of humanity, driven behind colossal walls by the relentless Titans. For a hundred years, peace reigned, a fragile construct behind Wall Maria, Rose, and Sheena. The narrator reminds us this long quiet spell has been violently broken, a stark contrast to the cheering crowds who waved goodbye to the Survey Corps earlier that day. This expedition, fraught with a thirty percent casualty rate, took humanity's best hope away just when the city needed them most.

Outside the walls, the Survey Corps faces the brutal reality of their mission. A lone soldier, pinned and screaming defiance, is devoured by a Titan, a stark illustration of the odds. Then, Captain Levi descends, a whirlwind of blades and motion, cutting through Titans with chilling precision. His squad, including Petra, move to support him, while Hange Zoe dispatches a Titan with manic glee, muttering to it like a specimen. Levi, meanwhile, cleans his bloodied hands with a fastidious handkerchief, a stark, unsettling habit amidst the gore.

Levi kneels beside the dying soldier, who questions the meaning of his sacrifice. Despite his revulsion for filth, Levi clasps the man's blood-soaked hand, a rare gesture of human connection. He promises the fading soldier that he will eradicate the Titans, a vow that carries the weight of a dying man's last hope. The soldier's grip loosens, and he passes, his final moments eased by his captain's solemn oath.

Commander Erwin arrives, his face etched with grim realization. He orders an immediate retreat to Trost, informing Levi that the Titans are moving en masse, indicating a breach. The news that the tragedy of five years ago is repeating itself hits Levi hard. The elite soldiers mount up, their expedition now a desperate race back to a city under siege.

Back in Trost, Armin stares at the evaporating remains of the Titan Eren emerged from, grappling with the impossible truth. Eren, unconscious, drifts in a dreamlike state, hearing his mother's voice, seeing memories of childhood. This brief comfort is shattered by visions of Titans and Armin's terrified face. The internal peace gives way to pure rage, a vow to exterminate every Titan, which ignites his awakening.

A chilling flashback reveals Eren's first transformation, bursting from a Titan's neck in an explosion of flesh and blood. The newly formed 'Rogue Titan' immediately turns on its captor, brutally destroying it with feral, oversized blows. It then rampages through Trost, methodically slaughtering other Titans with martial skill. Armin, observing from a rooftop, notices the Titan ignores humans entirely, a crucial detail that begins to reshape his understanding of his friend's monstrous new form.

Eren awakens to find himself, Mikasa, and Armin surrounded by terrified Garrison Soldiers, led by the panicked Captain Kitz Woermann. Mikasa stands ready to kill, her blades drawn, intimidating the shaking soldiers. Kitz demands to know if Eren is human or Titan, hysterical in his fear, while Eren grapples with his impossible, regenerated arm. Rico Brzenska logically points out Eren's undeniable danger to the walls, fueling Kitz's determination to eliminate him.

Mikasa coldly informs the soldiers that she will tear through them all to protect Eren, her unwavering loyalty a terrifying force. Her words hold weight, silencing the men, but the standoff remains. Eren, meanwhile, looks at his regrown hand, finally understanding the source of their terror and hatred. He searches his fragmented memories, realizing his friends are in mortal danger because of him.

Captain Kitz Woermann raises his hand, preparing to give the order to fire the cannon, as Armin watches in despair. Eren, clutching the key around his neck, is overwhelmed by a vivid memory of his father. Grisha Yeager, frantic and weeping, injects a young Eren with a mysterious liquid, whispering about a hidden memory and a basement that holds humanity's salvation. Grisha insists Eren must master this power, and the boy's scream echoes just as the cannon's trigger clicks.

Kitz Woermann screams the order, and the cannon fires, a massive shell hurtling towards the trio. Mikasa prepares for a desperate jump, but Eren, his face a mask of primal instinct, bites his own hand. A massive explosion of lightning and steam erupts, and a skeletal arm and ribcage materialize, catching the cannonball mid-air. Armin and Mikasa are sheltered within the monstrous form, staring in awe as the Titan flesh begins to evaporate. The Garrison soldiers stand frozen, staring at the terrifying protector Eren has become.
