In addition to the previous casting news, CSI: Crime Scene Investigation will feature Grant Show in the upcoming arc leading to Marg Helgenberger’s (Catherine Willows) exit from the crime drama. (Spoilers after the jump!)
According to TV Line, Show will play FBI Agent McQuaid, the partner of SAC Pratt (played by Matt Lauria). The FBI swoops in to “help” the CSIs with a case, and Catherine and McQuaid find themselves drawn to each other—leading to a “steamy affair”. Show will appear in multiple episodes starting in November.
