Penultimate episode. Written by James Goss. Ingenious that the Dalek Emperor of the Restoration had led the Entity to come to the Planet of the Mechanoids. This forced the Mechanoids into an alliance with the Daleks against the Entity. Interesting how this all played out from there and how the Dalek Emperor did certain things itself.
