Chuck is dangling out the window. As Olive runs to the bell tower the priest claims he was trying to help Sister Larue. Olive doesn't want to hear it. She slams the door in his face and runs up the bell tower. The priest picks up a shovel to break down the door, but he is quickly relieved of his task by Emerson. As Emerson debates the merits of roughing up a priest in a church, Ned and the nuns spy Chuck in the bell tower. Ned and a few of the nuns run for a donkey cart loaded with hay while the rest of the nuns drop to their knees in prayer. Olive has finally reached Chuck. As she pulls her up, she apologizes for being cold. Chuck is the closest thing to a sister she has and she doesn't want her to get hurt either emotionally or physically. Chuck wants Olive to know who killed Sister Larue. It wasn't the priest, it was Pigby! She was holding the truffles and it is encoded in Pigby's genes to go after them. It was purely unintentional. Since Olive is about as big as a labradoodle, she yells at Pigby to help pull. Pigby grabs her habit and the two of them pull Chuck to safety. As Olive praises God, the bell hits her in the ass and she falls out the window. Is that another message from God? As she falls she finds a sense of peace. She hopes Ned and Chuck are happy, that Emerson becomes rich, and that a slice of apple pie served warm will always be known as an "Olive Snook." Luckily, the Piemaker has moved his ass (literally) into place and Olive falls into the donkey cart's hay pile. Emerson congratulates Ned on his nice catch. Chuck waves from above.
The facts were these: In her former life, Sister Larue the mycologist was hired by a mega corporation to test the cultivation of the elusive Italian white truffle -- until all funding was pulled when testing went badly. She decided to use the convent and their truffle farm for her own ends. But labs need equipment, and she found her way to Leatherface's restaurant and began trading him truffles and whatever the kids are calling it these days for lab equipment. Years passed and then she finally reached her goal of cultivating the perfect white truffle. She was going to be filthy rich and was planning her departure from the convent. She brought Leatherface a last truffle, but was followed by Mother Superior who was desperate to bring a stray lamb back to the fold. She wrote the Dear Leatherface letter and bricked up the tunnel to force a break up. Meanwhile, Father Dedonde went to the bell tower to speak to Sister Larue. He was expecting contrition, not a false nun and a million-dollar discovery. He told her to pack up and go and she was doing just that when Pigby accidentally pushed her off the bell tower. The Priest assumed he had convinced Larue to kill herself.
