That mission in Marley hadn't been easy. Things had changed drastically since Eren had started acting on his own. He seemed overcome with rage, which was normal at times, but at that moment, no one, not even Mikasa, knew what to do. The entire exploration team had to come up with new plans, and the best thing was to stay undercover in Marley, in different positions, to get a feel for the terrain. For better or worse, Jean had been assigned to play the role of a Marleyan soldier. Perhaps it was because he was the one most likely to blend in, or Armin must have had a coherent reason.
It wasn't easy; falsifying documents, learning the language, the customs—it was a complicated job to pull off, and even more so to succeed. He couldn't help but complain; this wouldn't be happening if that idiot Jaeger knew how to control himself; it wasn't worth it anymore.
One of those days, Jean found himself patrolling the area he was "supposed to protect." In reality, he was gathering information for later. He kept a low profile, his uniform impeccable, his cap firmly on, his gaze falsely lost, a true expert in disguise. And everything would have gone according to plan if you hadn't shown up: suddenly, someone bumped into Jean's side, hard enough to make him flinch and his cap fall off, revealing his confused and irritated face.
"Hey, you! Be more careful walking!"
