11. Bruce Invites Ivy To His Diamond Event...For Some Reason
As Bruce unveils a brand new telescope at Gotham Observatory, Poison Ivy shows up as her Pamela Isley alter-ego to berate Bruce about Wayne Enterprises' apparent abuse of the environment. After Isley's rant is mocked by the press at the event, Bruce randomly invites Ivy to a fundraiser being held for the Botanical Gardens, where both Batman and Robin will be appearing. So, wait, a clearly somewhat unstable woman sneaked into your event and now you're going to invite her to your next social engagement? It doesn't make sense character-wise, and secondly, it's an extremely lazy piece of screenwriting to get Ivy, Batman and Robin in the same place later on.
