HE DOESN'T REALLY GET APPLE and because her actions, to him, don't seem very consistent (you were angry at me and ignored me but then you helped me and didn't ignore me???) he doesn't know how to read her... He does assume things aren't 100% okay between them, but since he doesn't get her and she doesn't seem like she's going to take the initiative he's fine with leaving things as they are. He appreciates that she helped him during Mira's game, but since he didn't get a chance to thank her he was kinda like... o well... i guess that's how it is...

probably if there comes an occasion where the frustration of not being able to deal with apple outweighs the effort it would take to talk to her he might try, though idk how successful it would be. he finds the initial reason apple got mad at him was pretty unreasonable so that + his being unable to read her actions makes him think she's just generally kind of whimsy in an uptight way.

state of the apple?
