Ivy is notorious for liking nothing, but her plants and well, Harley. Could it be that she likes Harley as more than a friend? I’ve read numerous comics, which where NOT fan-fics, that indicate that this might be so.
In one Harley was talking to Batgirl saying, “Ivy and I do that.” And Batgirl wants an explanation so Harley says, “You know, the stuff that is rumored about you and Super Girl.” To this Batgirl gives a look of disgust, which indicates that Harley and Ivy must have had sexual relations.
Harley might be searching for love from anyone that might be willing to give it to her, but I think that with Ivy it might not just be “for fun”. What do you guys think?
