>>55838433His defensiveness outs the truth pretty badly too. He sees a post that starts with "Ashfags" with Yugioh characters in the attached image and he IMMEDIATELY believes that they're calling Ash a cheater just like the Yugioh protagonists. He can imagine them doing nothing else, because his mind has already connected that dots that Yugioh characters are cheaters and Ash is a cheater, so that MUST be what the post was saying.
It's a tacit admission that he knows Ash is a cheater.
