Nick Savarese is Kalinda Sharma's ex-husband, whom she hasn't seen in several years and went to great lengths to hide from. Their relationship was very volatile, in and out of the bedroom, and he appears dangerous. He comes to the firm of Lockhart/Gardner in season four under the guise of wanting advice on how to get a city contract for his tow truck company, but that business is merely a front for other illegal interests. Kalinda tries to keep his identity secret from everyone as long as possible.
