attack on titan is a fairly popular series and I don't want to ruin anyone's enjoyment of it so - comment here if you'd rather avoid spoilers! Armin is from chapter 55, which was released on the 7th of March and it's pretty far past the anime's timeline.

I can either avoid tagging your character, or I'll avoid putting spoilers in brackets/meta if you'd prefer! comments are screened for your convenience. thanks!
