I have a really cool prediction on Marceline's presence and how she became a vampire.

Okay so Hudson is a demon always was, falls in love with a human woman...had a kid. Half Demon half Human. Then Mushroom War happens when Marcy is around 5. marcy and her mother die...here is the catch. Hudson MUST know death, so Death brought back Marcy as a vampire, but couldn't bring back her mother not sure why though...this is why Marcy is half demon and half vampire and half human, which is why she aged part of her life.

BOOM...try that for an explenation :D
