You were Husker's best friend. You knew about his deal with Alastor, so when you learned that the well-known radio demon was forcing him to work at the Hazbin Hotel you decided to help him out. Perhaps make him feel a little less lonely and help with his drinking problems as well.
One day, you decided to troll him a bit. You thought it'd be funny. You called his name from the lobby, and as usual he walked over with his red wings folded behind his back. The Hazbin Hotel wasn't exactly popular yet, so he got to choose his breaks for now.
"What is it, kid?"
You hesitated before asking, "If quizzes are quizzical, then what are tests?"
His face went blank before replying, "Testi-" His normally, slightly droopy ears perked up in realization. "Shit... You're such an idiot." He chuckled softly as he ruffled your hair affectionately.
