 thoughts were that she and her family went through a severe mutation 
that made them more vulnerable to vampirism, then one of them (her mom, 
maybe?) got infected and bit the others. I only say her mom, because 
Marceline's mom isn't shown and I think it'd be an interesting character
 dynamic if Marceline's dad had to kill her or something, realizing 
belatedly that he or Marceline was infected, and ended up going slightly
 off his rocker. Or he could've been a sociopath to begin with, that 
would be cool too.  |
