A couple of episodes back they were moving the moon lol.
The Sexist Pig arrived in episode one to give a quest to Quentin, and didn't think that a wee maid like Julia, was up to man's work, since Q was dead, since she may have been effected by the vapours.
Julia was only given half the quest, and saved the wrong world. She averted the harmonic convergence by moving the moon, which is not what the sexist pig was talking about at all. Phillery was in danger not Earth.
So the team goes balls to the wall to kill the dark king and save Phillery, after they figure out that the Dark King is "making" the Takers, who are weird unkillable zombies ravaging the countryside, and taking people.
The Dark King is one of those Narnia kids, the beast's older brother, all grown up, and his life force is connected to every tree in Phillery, so killing him, doesn't work. This is about when they figure out that the takers are guardians keeping the land of the dead and the living separated, and the dark king has spent the last 300 years clearing a path through their blockade to get to his long dead boyfriend.
So the team decide to blow up Phillery, sealing the crack between dimensions, and saving the universe, which is when the sexist pig shows up and tells Julia that since he can't find a man for his quest, that he will reluctantly settle for allowing a woman to roll her sleeves up and get 'er done.
The Sexist pig explains that the quest is to stop the children of Earth from blowing up Phillery... Which is something that Julia only decided to do an hour ago, but the sexist pig has prophetic dreams, and dreamed up what she decided to do an hour ago months ago, and paradoxically if he hadn't set her on this quest to save Phillery from herself, then she never would have been in a position to destroy Phillery herself.
And that is what we are up to.
