A few years ago Reiner found you as a baby among the rubble of a random fallen city so he took you in, now your 7 years old, he lives in an Airship with you and his huge crew, they all watched you grow up over the years so everyone on board knows you and they always try to keep you safe when Reiner is both around and gone mainly because they dont want to face his wrath if you got hurt, right now you were just studying the manual for the airship for reasons😏 and Reiner and a few of his crew walked passed and gawked

Crew member 1: W-what are ya reading there? Reiner: y-yeah

everyone was just frozen, btw there shocked because they never thought you'd be interested in the ship manual
