I don't even think they see a difference between liking each other romantically vs platonically. They just trust each other a ton and know they like to be together.
Tbh idk if there was a "moment". Levi is slightly biased towards Noa when she acts nice to Isabel and Furlan (she also tries to be nice to him, but he refuses to trust her). She also took care of their bodies after they passed so that makes him appreciate her more +
To fall for a handsome guy that favors you haha. Either way, I think the two of them treated each other like a partner before either of them realized that's what they could be. Conversations just came easy between them, they were embedded in one another in the blink of an eye
Historia already got the bunny ears so I'm going with Noa's second spirit animal (stray dog with a really sad beggard look that follows you at the park)
Noa is never mean to Levi but he likes it when she is sarcastic or passive aggressive. I think that if she directed it at him he would react more like this though
@rosehollow_amor yes, and i think the problem is that aot often gives its women parallel arcs without letting them meaningfully intersect. mikasa, annie, historia, ymir, sasha, etc. can have rich individual relationships with men, but they rarely get enough sustained interaction with each other +
