when Eren was fighting against Reiner and Porco, you noticed Porco got out of his Jaw Titan form, you saw how badly injured he is, his right eye was missing, his half face was covered from steam smoke, his face is bleeding so much, you noticed Falco was in his Pure Titan, Falco was about to eat Porco! Porco decided to accept that he'll no longer fight and seeing his brother, Marcel's memories. (What will you do? Save Porco, or let Falco eats Porco?)
