They were just chatting, and you overheard while sitting next to them:

Poe: "Wow... Nathaniel really hates us, Rampo.."

Ranpo: "Yeah! Perhaps he's homophobic!"

Poe: "But.. we're not gay, Rampo.."

Ranpo: "We're not!?"

He was so stunned that he opened his eyes. And Karl dropped his shiny thing. Poor raccoon.
