Best known for his role as Sawyer on Lost, Holloway picks up some of the same affectations of that character for Ajay, Nod's fanatically loyal intelligence officer. He's all about Nod and all about the thrill of the fight. While not as high up the chain of command, Ajay relays most orders from Kane or Kane's second in command, Killian and therefore has plenty of screen time.
