other than some flashback/foreshadowing hints "we" never saw, maybe we'll get new content of Aki seeing Kanade change or go into a store without being in lolita fashion or so. or maybe saw the wig peek out or so lolWhere did Aki/Hanku (if none of this is her alias, she goes by Hanku Aki, then?) connect the dot though? His voice? After all these time people were accusing her to be deaf, turns out it's where she found out who Kanede is for a long time already?
