Daddys little monster - Daddys Little Monster

Finn and Jake are spotted by Marceline, who gives chase.

After narrowly avoiding their demonic friend, the duo run into the now-benign Hunson Abadeer, who explains that he only wanted Marceline to follow in his footsteps and rule the hellish realm.

The truly depressing thing about their relationship is that Harley never listens to Ivy.

This Harley is a far cry from the Harley who would betray Poison Ivy and Catwoman to free the Joker from captivity.

The second shows a scene in which flies in abruptly to tell Marceline that he wishes for her to take over the family business and rule the Nightosphere.

In the origin for Harley Quinn that they set in Batman: The Animated Series, her thesis holds true at least for herself.
