From season 3 ep. 11 Night Shift. Carter and Keaton spend some last moments together before she goes off to Pakistan. Benton walks in on them, laying on her office couch. I Cinta how Carter tries to hide behind the book with the Pakistani guy on it!
Great DVD extra about Noah and Eriq and their characters Carter and Benton. It also has the famous Carter/Benton special handshake! Credit goes to bemyguest80 aka Claire!
