A father suspects his retarded son of killing his daughter. Simone and Sipowicz get the case. Lesniak keeps reporting on James' condition. Morrisey's tactics with a suspect in a murder don't sit well with Fancy; however, the facts in this case match Andy & Bobby's case. While Simone and Morrisey work out the details of their combined case, Andy and Greg pose as Hasidic Jews to recover a stolen Torah. Sylvia takes another test (results positive) and asks Andy to be discrete. Later she discovers his level of discretion.
