by now, we all know that joker's glasses are fake and that they act as a mask for him in the real world. have we ever considered the implications of who knows that fact?
in akechi's rank three, joker is comfortable enough to not only take off his glasses, but he actually gives them to akechi. he doesn't feel the need to hide his true nature from him.
in sumire's rank four, joker is comfortable enough to take his glasses off and try new ones on. he's willing to let his true self show while having a sort of playfulness while trying on different pairs.
yet maruki never learns that his glasses are fake and in his rank 10, they joke about their glasses steaming up. joker never fully trusted maruki, no matter what the dialogue options may have hinted at.
