This latest installment of Babylon 5 is in two parts: the first, is about an entity that has possessed a worker. It wants to be exorcised, but Colonel Lochley prevents the priest, and sends it and the host both back to Earth. The second is about Galen trying to dupe President Sheridan into assassinating the future Centauri emperor to stop him possibly attacking Earth in 30 years time.
