Defiantly, Harley decides to pull the original heist she planned herself and heads off to the Gotham Museum of Natural History to steal the Harlequin Diamond. Harley evades the security system with ease, but then the alarms are tripped by Poison Ivy, carelessly stealing specimens from the museum's lab. Annoyed, Harley smashes the display glass and grabs her diamond. The two meet for the first time and exchange words as they are cornered by the police. Harley grabs one of Ivy's specimen bottles, attaches it to her gun and shoots it as a projectile, creating a cloud of gas that disables the police and lets them get away. As they speed away in Ivy's car, Ivy says, "This could be the beginning of a beautiful friendship".
