I decided to draw Annie with her hair down instead of in her iconic messy-bun thing she wears. I’m totally going off on a head-canon here but I want the kind of relationship I imagine Armin and Annie having. The two of them have both done things they didn’t want to do, they have blood on their hands, they took on an immense responsibility at a young age, and the hopes and dreams of their loved ones was placed on their shoulders. I imagine they are incredibly supportive of one another, and while they may not be so much a very open PDA relationship they share a deep intimacy and love for one another. Even more so, they respect each other for their strengths and weaknesses.
I also believe after he eats Bertolt that Armin’s attachment to Annie amplifies deeper than what it was previously. I imagine when he told her what happened it was a very difficult conversation for them both.
