Bubblegum (Bonnie) x Ice Queen (Simone). What if these two were the last ones on Earth and had to be together to survive an isolated island and make it back to civilization. After a while, Bonnie manages to dull Simone's insanity from the crown, making it easier for her to love her queen.
Simone: "Well, well, well. It took being the last ones alive, but I finally got'cha, Princess."
Bonnie: "Ease up, Ice Hag. If I had better options..."
Simone: "But...you...don't. (Pokes her nose)"
Bonnie: [EXASPERATED SIGH] "Come on. Let's make the best out of these lemons."
Simone: "I love you, honey."
Bonnie: "Yeah, yeah. I know."
