Vengeance (PNX episode)

The Phoenix-X is taken over by the Boosti, a species in which their bodies merge with ones own. With the advantage of being away during the take over, Armond and the Captain return to the Phoenix-X to do what they can to save the crew - unfortunately, Daniel's powers are taken away by an X follower, except for a tiny fraction, making it that much more difficult.
