AOT (AU, part 2)

Eren's Current Status: 15 years old, a secret elite human operative under Levi and Isabel, has not met the 104th (Armin/Mikasa), and has not met the puppy yet. The Necklaces: Grisha's key and the unbreakable godess crystal necklace are hidden under his oversized red scarf, completely sealing his Titan powers and keeping his eyes a natural, calm blue. The Physical Marks: He carries permanent, human scars (including the deep knife slash on his cheek) because the necklace suppresses his Titan healing factor. His Personality: Quiet, disciplined, hyper-vigilant, and highly skilled at domestic tasks like sewing his own gear. Dangerous warning looks to any nosy civilians or soldiers who try to get too close or ask rude questions. Hange Zoë & Erwin Smith: Hange is deeply fascinated by the microscopic details of the unbreakable goddess necklace, suspecting it holds the key to altering Titan biology. Commander Erwin keeps Eren’s true identity as a "Yeager" locked away as the highest-classified military secret in Paradis, shield-guarding him from the corrupt Royal. The Status of the Alternate TimelineThe 104th Cadet Corps: Eren has not officially met the 104th recruits yet. While Armin and Mikasa are training or stationed elsewhere, they are completely unaware that the scarred boy they saw years ago is living as the secret shadow of Levi's squad. Eren will silently save Armin from the Bearded Titan in Trost using his flawless human blade work, vanishing into the steam before anyone can identify him. The heavy wool of the oversized red scarf was the only thing keeping the chill of the stone barracks at bay. Eren sat in absolute, unmoving silence, his right hand holding a silver needle with the steady, unshakeable precision of a seasoned surgeon. Spread across the rough grain of the wooden table was his green Survey Corps cloak. Yesterday, during a high-speed maneuver through the forest, a jagged branch had torn a huge rip straight down the center of the fabric. You're Eren.
