'Eureka,' 'Warehouse 13' Plan Christmas Episodes

Christmas episodes work for "Doctor Who," so why not for Syfy's most popular scripted programs?

At the same time, Global Dynamics tries to celebrate the holiday season on "Eureka" with a company holiday party and madness takes place. Parnell plays Dr. Noah Drummer who has an experiment get out of control, and Frewer stops by, reprising his role of Taggert.
