Harley lunges at him but he stops her. Joker chains her to the bed where she calls him a monster. At the apartment, Two-Face does not respond to anything as he lies, silently on the couch. Ivy is pacing around the room waiting for a phone call. The phone rings and as she answers, it is Maroni. Maroni allows her to access his mafia. Ivy smiles and thanks him. At his base, Maroni faces Falcone. Maroni tells him if he will help the heroes he'll help the villains. Falcone stands coldly until he leaves without a word.

Bruce watches a movie. Dick and Barbara are studying. Dick tells Bruce to keep the movie quiet as he can't focus. Bruce sarcastically responds and turns it down. On the TV a crime alert pops up. Bruce, Dick, and Barbara run down to the Batcave. At a plant observatory, people run, screaming. Poison Ivy is using the plants to attack the people. Batman, Robin, and Batgirl show up. Batgirl and Robin guide the people to safety while Batman fights Poison Ivy. However, after a fight she uses her powers to lunge herself out of the observatory.

Barbara Kean picks James Jr. up and tells him that she knows about Project Cadmus. He tells her she has no idea and that he just goes in and out. Barbara tells him lying won't work. He insists he is not. Barbara looks at him, concerned and then wonders.

At the museum, Cameron cleans up the shop and then prepares to leave. The curator, sadly, walks up to him and tells him that because of sales, the gift shop will be closes temporarily until the museum is able to produce more money to keep the shop open.

At the GCPD, Gordon and Sarah discuss date plans. Sawyer walks in and asks Sarah if she and Allen can have the day off. Montoya is still getting over Clayface's trickery. Sarah allows them and Sawyer and Allen leave. Gordon tells Sarah that Barbara is mostly at the mansion discussing the escapees and so he is free most days. Sarah asks him why Barbara is still talking about random villains she doesn't have to worry about. Gordon passes it off as talking about Gordon capturing the villains. Sarah again says that Batman captures the villains.

In the Batcave, Batman, Robin, and Batgirl interrogate Killer Croc and Mr. Freeze about Ivy's interest and what she usually did. They both tell them that she was very good friends with Harley and stayed with her when she broke out.

Batman battles him until Two-Face overpowers the hero. Robin and Batgirl find Ivy and they are captured and trapped in vines. Batman finds them and decides to alert the GCPD about this as they can't take on Ivy, Two-Face and the mafia.

Allen, Sawyer, and Montoya are called in by Sarah saying it is an emergency and they need to join a task force to catch Ivy, Two-Face, and the mafia. Sawyer ignores hers but Allen decides to leave. At a hospital, Jervis wakes up and finds out he is being held there until he wakes up and will be taken back to Arkham. He accidently orders a nurse to set him free and she obeys.
