Unrelated to your specific topic, but Harley might be the worst person in Ivy’s life at this point. Which I find interesting, because she was arguably the most positive person in her life before Harley turned into a villain and helped Ivy with her abandonment issues. At this point Quinn has been responsible for getting Ivy killed, let down constantly, and home wreaking her relationship. Harley only does nice things for Ivy when it best suits her own interests, like getting her into bed. If there writers actually wanted to project positive relationships and disavow toxic ones they would have Ivy push Harley out of her life completely.
