According to Entertainment Weekly, Original Sin will follow a new generation of Liars in a town called Millwood. Derek will play Wes, a handsome graduate film student working at the local movie theater who sparks a romance with one of the girls, but may ultimately have far-from-good intentions. The actor announced the news of his casting via Instagram back in November. "It's all happening in Millwood 🔥," he captioned the post. "Very excited and grateful to be apart of this 'killer' group of people…😏."
