Story
Early one morning, Ms. Kirstein is making breakfast for her and Jean. When he fails to come down after she has repeatedly called his name. She goes upstairs with an omelet she made still in the pan. Her intrusion infuriates Jean, he quickly forces her out of his room; slamming the door in her face.

Two years after Jean has left for military training, his squad is stationed in the Trost District to prepare for a likely attack on humanity's newest front line. As part of the training the trainees are to evacuate the citizens, Ms. Kirstein is among those who are evacuated.

Some time after their training, Ms. Kirstein makes her way to the trainees barracks. She runs into Eren Yeager and Mikasa Ackerman, and asks them whether the two of them have seen Jean. Shortly after, one of Jean's superiors lets her in. Worried, her motherly instincts take over and she begins bombarding him with questions. Embarrassed, Jean begins yelling at her; trying to get her to go home. She tries to give him a gift before she leaves, but he makes it painfully clear that he just wants her to go home.

She manages to hand the gift for Jean to the Garrison soldier who let her into the mess hall. In the gift was a note encouraging him to work hard and not be a burden on others, as well as an omelet she cooked for him. After seeing it, Jean thinks back to all the moments his mother was there for him. Because of this, he decides to make an omelet for the cook off. After winning, Jean contemplates visiting his mother the next day.

Return to Shiganshina arc
The night before the Survey Corps prepares to retake Wall Maria, Eren mocks Jean at dinner by calling him "Jean boy," which was the nickname that Ms. Kirstein used when she visited him during training.
