Just in time for their holiday episode (expect to see Scott Caan's Danny as Santa), Lenkov is planning the return of James Marsters as Victor Hesse, who murdered McGarrett's father in the pilot and, we'll learn, has a connection to Wo Fat. Like he's done with all the characters, Lenkov will give Wo Fat (originally played by Khigh Dheigh) a fresh spin. "There's buzz about Tia Carrere being Wo Fat," Lenkov says. "But we do have a man in mind."
