Do you think armin would rub eren's stomach after eating the bully for the first time?
This is a million years late but YES DEFINITELY
Eren tries to be as normal as possible but, well, kinda hard to do that when you just ate someone, and he is so overfull and the bully won’t stop squirming, god what an asshole, and it feels kinda good but he’s also just so full and he’s not really able to reach enough of his belly to really rub it like he wants, you know? (Plus it takes up too much energy, and Eren is feeling lazy and ready to enter a food coma, with his gut so full.)
Thankfully, Armin is there to help. He’s really weirded out by what just happened, but also grateful and maybe a little vindictively pleased, and he can’t really... do much to change it anyway, can he? So he just goes with it and helps Eren soothe his aching, overfull gut. They’ll figure it out later, right?
