Lydia rushes over to the model town to find Betelgeuse. She begs him to help the Maitlands.
Sure, he can do that, as long as Lydia helps him in return.
See, Betelgeuse wants out for good and in order to do that, he needs to get married. If he helps the Maitlands, Lydia has to marry him. Deal?
Lydia really likes the Maitlands, so she agrees. She says "Betelgeuse" three times and releases the foul-mouthed ghoul from the model town.
Betelgeuse emerges from the model with a creepy mobile on his head and his two arms rolled up.
Maxie and Sarah rush over to see what's happening and Betelgeuse unravels his arms into two long mallets. Two vertical backboards spring up behind them and Betelgeuse smashes the mallets on the ground sending Maxie and Sarah up through the ceiling.
It's that amusement park thing Charles was thinking about.
Maxie and Sarah both seem delighted by the fact that they're being abused by a real live ghost. They're not the sharpest knives in the drawer.
