As the armory explodes, turns into The Barn and Audrey, Vince and her dad Croatoan, fade, the Troubles are released from people around the world; including Jason Priestley, who played Audrey's boyfriend for a few Season 2 episodes. A month later, Haven has returned back to the idyllic town it once was.
Nathan and Stan are back at the police station fielding calls from locals to save cats from trees. Yep, idyllic. Laverne is no longer a poltergeist Trouble and we finally get to see her walking around, happy and in corporal form. Gloria and intern Vicki happily report that the there's not a single trace of the Trouble gene to be found within anyone's DNA in town.
