Starting tonight, The Good Wife rolls out its final four episodes – and it looks as though the story is going full circle, with Peter (Chris Noth) once again embroiled by scandal. But there are other plot lines to follow as well – such as the one involving guest star Megan Hilty (pictured) from NBC’s Smash, playing a former business rival and protégé of Diane’s husband. And another one, in which Alicia goes to Canada to defend an NSA agent, who has been detained there.
