|The study group arrives in Group Study Room F having just attended Pierce's Reformed Neo Buddhist funeral. Although still saddened by their loss they question the tenets of the religion, particularity the Energon pod they received which is supposed to contain Pierce's "life vapor". Ben Chang shows up and needles the group about their somber attitude considering how much they disliked Pierce. The group vehemently denies this just as a man introducing himself as "Mr. Stone" enters the room. He identifies himself as an employee of Pierce tasked to carry out a private inquest per the instructions of his boss's will. As he talks, two technicians wheel in a polygraph device and begin setting it up. Stone tells the study group and Chang that they will have to submit to a lie detector test to determine if any of them were responsible for Pierce's death.
|Everyone agrees to participate but they soon regret it after the questions Stone asks them bring some secrets out to light: Shirley is a platinum level donor to a Pro-Life organization which angers Britta, Jeff's Netflix account is being used without his permission by Troy and Abed, Chang leaves after inadvertently admitting that he masturbated in the study room, and Annie confesses she is overcharging Troy and Abed on their share of the rent. The group begin arguing over these revelations when Stone tells them they are ready to begin. He informs them that the first round of questions was just for equipment calibration. Jeff suggests to the group they should quit the test before the questions gets worse. Stone tells them that their participation is strictly voluntary but if they quit they won't receive Pierce's bequeathments from his estate which is valued at over 20 million dollars.
|After everyone agrees to continue, even more secrets are revealed by Stone's investigation: Shirley ignored Britta's vegetarian beliefs and served her a meat-like tofu substitute at her sandwich shop, Britta was high on marijuana during the baptism ceremony of Shirley's child Ben, Jeff kept souvenirs of all his sexual conquests including Britta's panties, Troy did not create his signature handshake with Abed, the group learns that Abed planted geo-trafficking devices in all of them, Annie once dosed the group with amphetamines to keep them studying for the Anthropology final, and Abed is revealed to have been "cat fishing" Annie to get her to make pancakes for breakfast. The group starts arguing again when Jeff pleads with the group to stop letting Pierce manipulate them. Stone points out that he stopped asking questions a while ago and that most of those revelations were volunteered.
|Stone asks them if they want to continue but Jeff tells him to give them a moment to recover from the last round of questioning. When Annie asks how they could all be such bad people, Jeff realizes the "lesson" this activity was meant to teach them: They are all as flawed as Pierce was, he was just more honest about it. Jeff then suggest that they embrace their imperfections and admit to it just as Pierce did. Jeff starts it off by admitting that he is such a narcissist he would rather look at himself naked rather than the women he sleeps with, Annie admits to hitting Jeff's Lexus in the parking lot, Britta only gives to the homeless if she is with someone, Troy has never been to Lego Land, Shirley admits to being passive aggressive, and Abed hates when anyone chews gum in his presence. With all their secrets now out in the open, Jeff defiantly tells Mr. Stone to continue his inquest.
|Stone starts the final round of questions with Britta who braces herself for the worst. Instead he tells her Pierce believed that she should stop hating herself and that her passion always inspired him. Britta is bequeathed a used iPod Nano along with a cylinder of Pierce's sperm in case she gives up her lesbian lifestyle. Shirley is next and Stone tells her that Pierce always had great respect for both her strength of character and business acumen. She is bequeathed Pierce's timeshare in Florida and also given a cylinder of his sperm. Stone addresses Annie and tells her that she was always Pierce's favorite. She is given a tiara he tried bequeathing her several years ago and along with some of his sperm. Stone then questions Jeff's sexuality again before bequeathing him a bottle of fine scotch and his own canister of Pierce's sperm.
|Stone tells Abed Pierce believed he was crazy before handing him a canister of sperm. Troy is then told that Pierce believed he had untapped potential he shouldn't waste. Along with the obligatory share of sperm, Troy is also bequeathed Pierce's shares to Hawthorne Wipes valued at 14.3 million dollars. The only condition is that Troy sail Pierce's boat, "The Childish Tycoon", around the world. It was a task his father, Cornelius Hawthorne, gave him to earn his fortune which he failed to complete. It was something he always regretted and wants to give Troy the same chance in order to become his own man. Jeff steps in and argues that the condition can be contested but Troy states that he will do it. The study group is shocked but Abed pretends to be okay with his decision. However, one of the polygraph technicians monitoring his vitals confirms that he is lying.
Mr. Stone and the study group are at a restaurant having a drink. Stone is inebriated and has dropped the dour façade he was using at the inquest. He reveals to the group that the cause of Pierce's death was dehydration from filling up all the sperm cylinders he bequeathed to the group.

|In the episode everyone but Abed is shown to receive a personal bequeathal from Pierce along with their complimentary canisters of his sperm. In one of the original drafts of the episode's script, Abed is actually about to be bequeathed something but refuses before he could be told what it is. He instead decides to forego his bequeathment in exchange for the phone number of the female polygraph technician named "Mara". This is done on his part as a homage to the 1992 film "Sneakers" which a flattered Mara immediately picks up on. After she accepts his proposal, Abed is told by Mr.Stone (originally "Kobayashi") that his bequeathment was a limited edition caricature of Muhammad (any images of the Muslim prophet are strictly forbidden by most followers of the religion). Writer Alex Ruebens posted a picture of the script page for this unfilmed scene HERE on his twitter account.
