damn, chapter 85 was pretty harsh, but let's take a moment to think about something, while yes levi kicking the door down could be levi being levi, but he also looked pretty miserable and it could have been that he was mad, and in agonizing pain because he didn't have to give erwin the serum so he wouldn't suffer, he had to let him die so he wouldn't suffer, I think he loved him so much he could stand to see him suffer any longer
