I’d start the episode where we left off, Dorothy being torn on the decision. I’d have Dorothy basically tell Leanne to fuck off and run, which would cause Leanne to lash out. Then with the outburst of emotion, I’d have Leanne reveal herself to have powers or not have powers. In either case, I’d have a monologue wheres she’s screaming about some of the questions we have answered.

A la “I CHANGED THE HOUSE PIN TO KEEP JERICHO HOME FOR YOU. I BLACKMAILED THE NEIGHBOR TO TRANSPORT JERICHO TO SAFETY. YOURE LUCKY TO HAVE ME”

Or

“I CHANGED REALITY TO KEEP JERICHO HERE FOR YOU. I BROUGHT BACK JULIAN TO KEEP YOU HAPPY” etc etc.

When Dorothy has had enough, they fight, preferably to the death. Maybe a fight scene all around the house, as a call back to all the rooms we’ve seen throughout the show, finally ending on the roof. Where Dorothy strangles Leanne with the only thing she has access to…. An Hermes belt she is wearing.

The cops come, see the house security footage of Leanne being a psycho or witch, the family gets to move physically and move in emotionally. Sean owns a restaurant and Dorothy works for a different new station, both in a smaller city. Maybe even a hint at Dorothy being pregnant.

Something like that would be a decent ending in my eyes.
