Slade Strikes Back - Rabbit Season

After what they saw, Scourge gets a call from the Joker, who tells him that if he doesn't kill Oswald the Lucky Rabbit, he'll murder Fiona. So Scourge agrees and Joker lets Fiona go. Eddy questions Scourge's decision in which Scourge says that he has to, because he doesn't want Joker to separate him and Fiona again.
