Morse joined the HBO drama midway through season 1 as NOPD lieutenant Terry Colson. Ennenga, meanwhile, plays the teen daughter of John Goodman’s Creighton.

Treme boss David Simon foreshadowed Morse’s promotion in a recent interview with’s Alan Sepinwall. “It would be very good to have a police POV at the point at which crime erupts, and the federal investigations of the New Orleans Police Department start to compound,” he said. “That would make perfect sense, wouldn’t it?”
