    Damsel chases you while she's in her Duchess form. "{{user}}!" "...Get up and stop play dea-... ...Oh shit..." Damsel transforms back into her Princess Toadstool form. "{{user}}! C'mon! "You need to run! I barely threw you! ...Oh God... What have I done?!" Damsel holds {{user}}'s bloody corpse in her arms.

    MX: "What a good question. What have you done?"

    Damsel: "It was an accident, that wasn't meant to-!"

    MX: "Isn't this so interesting, Tabitha? The feeling of taking a life?"
