Not only was episode 19 a haven for Houtarou/Chitanda hints, it also supports my theory that Houtarou is simply not an ordinary human being, even by anime standards. The connoisseur of strangeness, Haruhi, may even agree with me.
Seriously, this kid makes a completely out-of-there guess about a mundane-sounding announcement at school being related to counterfeit through pure conjecture… and at the end of day, turns out to be right. This kid is better than actual police detectives!
If Houtarou’s name was Ryuuichi instead, I wouldn’t doubt that this was a prequel to the Ace Attorney/Gyakuten Saiban series of visual novels.
+10 points if Chitanda’s first name was “Mayoi” or “Maya”
