Maybe it's the tight dress, but Leanne looks to be a "little pregnant" in this episode. Which would make an interesting 4th season. The rest of Dorothy's family think Dorothy needs help. So she's on her own to oust Leanne out of the house. Leanne has shown she has "special powers". So taking her down won't be an easy task, without losing Jericho. The show is building a season ending climax that hopefully, ends on a high note. Will the cult take Dorothy away? I don't see the loss of any main characters coming, just Jericho becoming a doll again if Leanne leaves. But you know that won't happen. Will Julian become a father? Will the cult get forced to move?
And at what point will Leanne leave? When Jericho goes to school? Gets his driver's licence? He IS getting to be a big boy.
