Overview
Marco returns a lost bag.

Summary
After dinner, Marco finds a forgotten bag in the mess hall and brings it to the boys' dorm. Seeing its pink color, Jean believes that it belongs to one of the girls, and Armin is eager to know what it contains, but Marco refuses to open it on account of privacy.

Marco decides to take it to the girls' dorm, but Jean reminds him that the commandant would be patrolling the halls. Armin then proposes the idea of using omni-directional mobility gear to sneak into the girls' room through a window. Jean is hesitant, fearing of being regarded a pervert if they are caught, prompting Armin to decide on waiting until the girls leave first.

Eren prepares to go to sleep, to Armin's shock, who questions if Eren is going to ignore Marco in his time of need. Eren reiterates his desire to quickly wipe out the Titans, explaining that tomorrow is an early day. Jean starts calling him names, leading to them bickering and Eren deciding to come along in the end. Outside the girls' room window, Armin, Marco, Jean, and Eren dangle from the roof, awaiting for them to leave. Mikasa briefly senses the boys, but they manage to trick her by mimicking cat sounds.

The girls finally leave and the boys enter the room. As Marco places the bag, Mikasa suddenly returns, to the boys' horror upon seeing her. She questions Eren on his presence there, as a Titan suddenly opens the roof and eats the boys. Inside its stomach, Marco is glad that they were at least able to return the bag.
