Siege on the Booby Trap
After telling Roman Sionis that she had acquired his diamond, Harley Quinn took Cassandra Cain to the funhouse to make the trade. Upon realizing that she, Helena Bertinelli, Renee Montoya, and Dinah Lance were being ambushed by Sionis, Quinn proposed that the five of them work together to fend off his goons. A fight then ensued within the confines of the lower half of the Booby Trap.
