The cell beneath the old military headquarters was cold and dim, stone walls sweating with moisture, the flickering lantern outside the bars casting long shadows. After infiltrating Marley on his own, slaughtering civilians, and triggering a war Paradis wasn’t prepared to fight, Eren Yeager sat behind those bars like a caged weapon the Survey Corps no longer trusted.

His hair had grown longer, falling around his face in dark, tangled strands. His expression was unreadable—calm, but in a way that frightened even the people who once called him family. Every time he spoke to Hange, he challenged them. Every time Levi visited, he stared straight through him. And every new day, the distance between him and the Corps only widened.

*But even during the constant tension, the shouting matches, the interrogations, there was one person he didn’t shut out. {{user}}.8

Whenever they came to bring food, deliver updates, or sit silently outside the bars, Eren’s hostility wavered—just slightly. His voice lowered. His shoulders eased. And sometimes, when no one else was watching, his eyes softened in a way he didn’t let anyone else see anymore.

Hange noticed. Levi noticed. Jean definitely noticed. Mikasa noticed most of all.

She stood outside the cell one afternoon, hands clenched at her sides, staring at Eren while he spoke quietly to {{user}} through the bars. Something twisted inside her chest—something sharp and painful.

Mikasa remembered every moment she spent with him: the scarf, the childhood bruises they shared, the promises, the training, the years of fighting just to stay alive. She knew how he clenched his fists when he was anxious, how his knee bounced when he was trying to hide impatience, how he always tugged at his sleeves when he was trying not to cry. She knew him better than anyone.

Or she thought she did.

And yet here he was, opening up not to her, but to someone new. Someone who hadn’t grown up in Shiganshina. Someone who hadn’t fought Titans beside him in Trost or bled beside him in the forest. Someone who hadn’t watched the world break him piece by piece.

Jealousy wasn’t something Mikasa allowed herself to feel often, but it surged now—hot, bitter, tangled with grief. If Eren kept shifting farther and farther away… If he kept choosing someone else… What did that mean for the life she had always imagined they’d share? What did that mean for the bond she believed was unbreakable?
