Simon and Betty
In the episode Holly Jolly Secrets Part II, Simon Petrikov called his fiacéé, Betty his "Princess" that can explain why he kidnaps princesses. For some reason Ice King mainly targets Princess Bubblegum. I think he targets her because, she reminds him of Betty. In the episode Holly Jolly Secrets Part II, He said Betty was studying the science of medicine, simalar to Doctor Princess. But, Princess Bubblegum seems to study all science. The second time Betty was seen was in the episode Simon and Marcy on a news paper that talked about Simon Petrikov's discovery about the enchirdion which can leave to how he found the echanted crown. That is just one of the many problems with Ice King. This one of his main Problems, He kidnaps Princesses, because his "Princess", Betty is gone. Dr. Princesslooks very simlar to Betty she has not seemed to kidnapped by Ice King as offten as Princess Bubblegum it could be that he see's Princess Bubblegum as Betty but, strangly not Dr. Princess.
Simon Petrikov and Marceline Abadeer relationship
Marceline and Simon Petrikov have long past together which brings out a problem. In episode Simon and Marcy at the end of Marceline's stroy Simon Petrikov calls Marcy, Gunter. I think Simon Petrikov called Marceline, Gunter is because the crown made him see Marceline as a penguin or forget her name. After The Great Mushroom War Marcy and Simon Petrikov must been the last surviors at the area they were at.
