Eren looks over at Armin's burnt up body. "Captain! He's still breathing! Hurry up and give him the syringe so he can turn into a titan and steal Bertolt's power!" Captain Levi holds out the syringe but then sees another soldier approach. "Erwin is badly wounded! You need to inject him!" Captain Levi stands up. "Everyone stay back. I'm giving the injection to Erwin." Mikasa tackles him and holds her blade up to his neck in defiance. Clearly there's some tension in who they have to pick to save.
