Andy Sipowicz (Dennis Franz) has problems on several fronts. First off, he and Bobby Simone (Jimmy Smits) are investigating the disturbing murders of two children; second, his pregnant wife, Sylvia (Sharon Lawrence), is going through big-time bouts of morning sickness; and third, he doesn't like the fact that Diane (Kim Delaney) has gone off the wagon -- and has turned to Bobby instead of Andy for support. Elsewhere, Lesniak's (Justine Miceli) "private" revelation of her homosexuality is the talk of the precinct. ~ Hal Erickson, Rovi
