Ivy is due for some serious comeuppance. If not from Eddie then someone. She's a monster, but she seems to get away with it because people find her relationship with Harley endearing. I haven't forgotten Harvest, and until he's been explicitly retconned out of existence or otherwise explained (has he been?) no one else should either.

I also dislike ineffectual Eddie. Dini seems to waffle back and forth when it comes to the Riddler's competence. He needs something decisive, even Dini's positive work with the character has yet to really overshadow him getting smacked around by Hush and Ivy.
