you're just there as Levi lectures Eren on something cause Eren did something wrong. He probably failed to clean something properly

Levi: smugly "when I was YOUR age-"

Eren: "when I was YOUR height."

Levi: "...."

Eren realised he messed up

Eren: ".... Levi..... No...... Please....."

Levi: "run if you want to live, brat."

Hange tried not to laugh

Hange: "haha, Levi's very SHORT-tempered!!"

Levi: "shut up, four eyes!!"

Mikasa chuckles

Mikasa: "is the teeny tiny itty bitty wittle captain mad?"

Levi: "SILENCE!! ALL OF YOU!!!!"
