S3, E7: Bosco confronts his past when he is wrongly accused of murdering a sexual-assault suspect. As his partner, Yokas, tries to gather evidence to vindicate him, Bosco turns to his dysfunctional family, including his alcoholic mother, Rose (recurring guest star PATTI D'ARBANVILLE - "New York Undercover") and drug-addled brother, Michael (CHARLIE DAY). Bosco also searches for his estranged, abusive father. Meanwhile, an emotionally overstressed Kim kidnaps her young son, Joey (recurring guest star KRISTOPHER SCOTT FIEDEL), from her ex-husband, Doherty. Also, Carlos tries to persuade Davis to be his roommate.
