While looking at an online escort site, Det. Lu remarks that he keeps thinking he'll see one of the boss's old girlfriends on there, and Det. Simms asks "One?" The boss was played by Tom Sizemore whose relationship with former Hollywood Madam Heidi Fleiss resulted in a May 2003 arrest and August 2003 criminal conviction related to him beating her. This arrest and conviction along with a prior December 2002 arrest for domestic violence were key reasons for the series not being extended.
