Eren took Jean to Hange for a check-up. After checking on Jean, Hange looked at Eren. "Continue to give the medicines I told you, Eren." Said. Eren nodded and He looked at Jean who was outside, blowing the snow off of him.

"Come on Jean, we're going.." Eren said and took him by the hand and started walking home. While protecting Eren from a Titan during a mission, Jean suffered a head injury and permanently lost his memory and now behaved in a childish manner.

"Eren... Eren, it's snowing.." Jean said excitedly. Eren smiled tiredly. Jean's entire responsibility was consuming him inside.
