Especially when Sharon's ex-husband Jack (guest star Tom Berenger) re-enters the picture to defend a confessed murderer who now wants to withdraw his confession. While Sharon and Jack play a legal game of cat-and-mouse, Jack ends up getting much more personal. "Their relationship becomes more hostile," Duff says.

As a result, things get much more serious on the relationship front as well. (Let's just say you'll be seeing a lot of the characters together when they aren't at the precinct. "It accelerates things for them in a way they weren't prepared for," Duff teases. "You'll see them up close."
