Epstein Didn't Kill Himself

Context (Spoiler warning): In one of the bad endings, Akechi (also known as Crow) shoots the protagonist and then you hear a guard screaming about how the protagonist committed suicide. If you don't get the bad ending and instead choose the right options to continue the story, then you'll hear Akechi say out loud in the speakers that he is going to kill the protagonist and lie to the population by calling it a suicide. This meme is extremely subtle, so you could post that on Twitter with no context and that'd work like a dog-whistle to everybody who've actually played Persona 5.
