Bruce, Dick, and Barbara watch the news and find out that people are rioting to keep Batman out of Arkham after the several times he's been denounced a murdered and the many times he has left several crimes to the unhelpful police. Sarah watches this and orders her police force to patrol the streets of Gotham. She has come up with a system so that half the force will patrol one week and the other half will handle the cases. It switches every week.

Barbara Kean and Cameron are on a date. They laugh and Cameron has an engagement ring behind his back. When Barbara turns around he puts it under her plate. When she looks back he is back to normal. She finishes off her plate and sees the ring. She thinks a couple left it there but Cameron tells her he put it there. She wonders why he got her a present but then realizes he wants to get married. She looks worried and leaves in a hurry. Cameron then looks worried.

Harley reaches a knife on a desk next to her and picks the cuff lock. She gets her mallet and escapes. In Gotham, she finds Two-Face and reunites with him. He looks worried and happy at the same time. Ivy, in her underwear, walks out of the bedroom and sees Harley. Harley realizes the two are together now and leaves.

Batman gets angry at them causing Harley to escape.

Maroni talks to his men about the missing month. They tell him he left to visit Falcone and he never cam back. There were several investigations but they never found him. A funeral was being planned.

Barbara Kean visits Cameron and tells him that she just panicked and her instincts kicked in. Cameron forgives her and they kiss. Barbara tells him yes and puts on the ring. That night, after Barbara is asleep, Cameron takes his Killer Moth outfit and puts it in the dumpster. Batman finds him and the suit and realizes that his suspicions were right.
