Pigeon hurls itself into Elsita's windmill house, and she brings it inside as Lefty says that that's his bird as well. They look for the note as Olive walks in holding the message, which Elsita takes from her hand. It turns out that Elsita is the daughter of the woman who owned the windmill where Jackson dumped the diamonds, right before the cops came in and hauled Jackson off. The wrote each other for twenty years and sent messages via carrier pigeon, and when Jackson died, he passed the message of where the diamonds were stashed to Lefty. When Elsa died, Elsita kept writing to Jackson, and she discovers that Lefty took over writing the letters after Jackson died. When Lefty broke out of jail, he hijacked the crop-dusting plane, and Pigeon flew out the window and lost a wing in the propeller, which crashed the plane and OH MY GOD THIS IS SO CONFUSING THIS IS LIKE TRYING TO FIGURE OUT A CHEKHOV PLAY WHERE EVERYONE HAS FOUR NAMES AND NO ONE EVER EXPLAINS WHO'S WHO EXCEPT THIS IS BETTER BECAUSE IT HAS MORE THEY MIGHT BE GIANTS BUT I MEAN GAAAAAAAAAH. Anyway, Elsa has the diamonds hidden in her leg or some such thing, because that is where this episode has taken us.
And then, a knock on the door, and Olive checks the peephole to discover, among others, Chuck, on the other side. Her moment has finally come to expose Chuck for the not-dead beee-yotch she totally is, but then...well, it's like in the TMBG song "Someone Keeps Moving My Chair" when they sing so meaningfully, "It's the ugliness man, Mr. Horrible." Just kidding. Don't look for any actual insight in those songs. But Olive has grown so fond of the aunts that she doesn't want to totally freak them out, so she steps outside and tells Chuck that she's there on a tart apple pie delivery, which sends the coded message that her aunts are inside. Olive goes back inside and hustles the aunts out the back, but back in the car, Lily takes a deep breath and says, "I don't think we've been out since...Charlotte?" She spots Charlotte in her rearview mirror, but with one turn more of the windmill blade, she's gone. The police come to take Lefty Jackson Conrad Harry Larry Marry away, and we learn that the long-distance relationship between Lefty and Elsita kept going. And, finally, Ned and Chuck don beekeeper outfits and dance among the bees on the roof of the Pie Hole. This show is crazy.
