I have to admit I didn't think much of it at first. Then I saw the post and went back and it sorta makes a lot of sense.
Ah, first time I saw that, I thought that was Kon talking to Ririn. And she was referring to how Kon is dressed like a quincy too(Ishida sewed that symbol on the back of his head). But after rewatching it, that is Ichigo talking to Ririn, not Kon.
