Complete story — includes the ending
The populace is divided over whether Eren is their savior or their end. He is brought to a military tribunal where Commander-in-Chief Dhalis Zachary will decide whether he should be handed over to the Military Police Regiment or the Scout Regiment. The Military Police wants Eren executed, seeing him as a danger, while the Scout Regiment wants to use his ability to retake Wall Maria. Eren angrily calls out the Military Police for their cowardice and selfishness. Levi brutally beats him in retaliation; despite his anger, Eren does not transform as feared. Levi and Erwin use this to show that the Scouts can control him and kill him if need be. Thus, Zachary gives him to the Scout Regiment. Erwin and Levi make amends with Eren for beating him up, though Eren understands it was necessary to get him under the Scouts' supervision. As he is getting treatment, they are bewildered to see that the tooth Levi knocked out has already grown back.
