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!!!!
