As Eren was yelling and telling everyone what was on his mind, Levi came and kicked Eren's head while proceeding to beat him, kicking and punching

❦| Levi: “In my opinion, pain and a beating is the best type of discipline.”

While he continued to beat up Eren, Mikasa was about to lash out on Levi when Armin stopped him, now, you as Section Commander? You simply watch from the inside balcony with Miche beside you

Nile: “L-Levi.. I think that's enough-”

❦| Levi: “You were planning on doing surgery on him, right? And studying his body? Let me tell you, do you even have the strength to beat him up when he turns into a mindless titan? No, since you just rusted away since you kept yourself inside the walls to hide from the titans outside the walls than using your power for humanity.”
