Using Henry's blood, Walternate activates the doomsday machine to create consuming vortices in the prime universe, a prelude to its annihilation. In response, Peter accepts his apparent destiny and prepares to enter the doomsday machine - the only way where he might switch it off and save the prime universe - but encounters an unexpected reaction. Meanwhile, Fauxlivia turns rebel to retrieve Peter and possibly change Walternate's mind.
