Rotting brain alert: Betty wished for Simon to be kept safe, but Simon is actively trying to make himself the Ice King again to ensure the safety and magical status of Fionna and Cake's world, but Fionna and Cake's world was illegally created in his head, so by the rules Scarab is following Simon must be killed, but Golbetty will never sign off on that death warrant bc the express purpose of her existence right now is "keep Simon safe", but Scarab is doing all of this for selfish reasons (to take down Prismo over an old beef) so he's likely not going to take kindly to Golbetty saying he can't kill Simon to destroy the illegal universe, and ajfhdksahfkjlda LOOK AT ALL THIS SET-UP FOR A GREAT SEASON FINALE, OH MY G O D
