Warning: If you don't want to know what happened in this episode, don't read this photo recap!

As the storm looms over Haven, Vince tattles on Dwight and tells Audrey that Dwight plans on giving Croatoan the crystal that controls The Barn, so that Croatoan will agree to let him keep his daughter, Lizzie.

Audrey asks Vince to search his programming to find out what use Croatoan, the great and powerful, would still need with the crystal. Turns out, Croatoan knows that the device still has the ability to banish him and The Troubles forever. So Audrey and Vince mission to stop Dwight from making a huge mistake.

Meanwhile, on the outskirts of Haven, clone Audrey and Nathan are still puzzled by a few things: Why can't they remember how they got here? Why don't they know where they're going next? And why is Nathan's head bleeding?

Dwight hasn't turned his back on Haven after all. Vince, Audrey and Dwight hatch an elaborate plan where it looks like Dwight is escaping the gunfire of The Guard to deliver the crystal but it's all just a ruse to get Croatoan to come to the old armory.

Once Croatoan takes the bait, Dwight tosses Vince the crystal and a new Barn is formed and Croatoan seems trapped… until the walls start shaking. It was a great plan and we give our team an A for effort but sadly, it's not enough to hold Croatoan. The Barn is powered by the aether in Croatoan's body and Croatoan has to power the structure willingly and yeah – we know how that's going to turn out. Group: 0. Croatoan: Umpteenth Win.

Clone Audrey tries to keep Nathan from asking too many questions about their past but Nathan can't shake the feeling that he's meant to be somewhere else. His insistence causes clone Audrey's memories to come back to her and she realizes that Nathan belongs on the other side of the fog with the real Audrey. She sacrifices herself by walking him back into Haven, where he regains his memories and a fighting chance to save Audrey.

At the perimeter of the fog, Dwight and a very well dressed ghost Duke, who only communicates telepathically and whom Nathan cannot see, meet Nathan. The guys give Nathan the directive to go save Audrey, now! And Duke later tells Dwight that if he truly believes that his daughter is real then Croatoan won't have any power to take her away from him.

Audrey's agreed to go back to being Croatoan's evil daughter to keep her dad from raining Troubles on Haven. But Nathan shows up and halts Audrey's evil transformation. Naturally, this pisses Croatoan off so he kills Nathan with an aether bolt, but then after Audrey goes all the way off on him, Croatoan backs down – finally – brings Nathan back to life and then agrees to disappear into The Barn. Underneath it all, Croatoan's just a dad who wants his daughter to be happy.

Of course, a plotline can never been sewn up simply, when it comes to Haven. Vince appears and tells the group that in addition to a willing Croatoan, The Barn also needs the catalyst of love – Audrey – so that the Troubles will leave Haven forever. It's a heart wrenching decision, but both Audrey and Nathan know that they have to sacrifice their love for the sake of Haven.
 

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. 

On his way to join Dwight, Nathan helps a distressed woman, who's car is stalled on the side of the road, with her baby in the back seat. The woman is Paige who just so happens to look just like Audrey/Lexie/Mara/Sarah/Lucy. The baby's name is, James – yep, just like Audrey and Nathan's son. And if you're starting to get the sense that this whole scene with Audrey in distress on a road with Nathan coming to her rescue sounds a little familiar—it is! See how it all began with this flashback scene from the very first episode.  As Nathan, Paige and baby James drive off, destined for their happily ever after; Croatoan and Vince watch over them, approvingly, from front row seats of The Barn— an unlikely duo united by the common goal of eternally safeguarding Haven.
