Personally i thought that hunson just left Marceline alone in the world for whatever reason. i mean, she's always seemed to have resented her father. the original demo for the fry song had her asking herself why her dad fathered her if he didnt want her so..

yea

thts just my opinion

And i guess that simon just left when he completed turned to Ice King and marceline was alone again, as in Memory of a Memory.
