Past Imperfect - S1.E8

Nick receives an ultimatum from Jim to either reveal the dark past to Karen or he will do it for him. Infuriated by this whole no way out scenario, he promises instead to break off the relationship. Later after finding his car vandalized, a golf buddy of the deputy mayor uses that connection to involve the reluctant detectives of the 8th Precinct in his nasty battle with an ex-girlfriend for custody of their son. In the midst of all this, Greg Hermanson, an old friend of Jim who served with him in the Gulf War comes to visit and purge his soul of something that has been slowly eating at him for years.
