In the study group's third year at Greendale, Troy and Abed move in together and throw a housewarming party at their new apartment. As the guests arrived, Abed proudly showed off his Indiana Jones Diorama to them. It paid homage to the iconic opening scene from "Raiders of the Lost Ark" . Later that night, the roll of a Yahtzee die decide the fate of the party goers as six diverging timelines are created. The diorama (specifically the boulder), along with a few other items ended up playing significant roles in how each unfolded. The Indiana Jones diorama's first appearance was in the Season Three episode "Remedial Chaos Theory" and it makes subsequent appearances in the background of the apartment throughout the rest of the season.
|In the Troy and Abed's third year at Greendale, Troy and Abed move in together and throw a housewarming party. Inside their home, the Indiana Jones diorama is Abed's pride and joy which he considered to be the centerpiece of the apartment. He shows off his creation to all the study group members when they arrive for the party. It recreated the famous sequence in the Indiana Jones movie "Raiders of the Lost Ark" when the archaeologist is fleeing from a giant boulder. Later that night, the pizza delivery guy arrives while they are about to start a game of Yahtzee and Jeff proposes that the roll of a die will determine who will go downstairs to get the pizza. As Abed suggests, he inadvertently creates six different timelines and the boulder becomes one of many various items which factors into how the diverging scenarios plays out. In most timelines the boulder is knocked loose from where it's placed on the diorama and Abed catches it before it rolls off of the table and onto the ground.
|However, In the timeline where Troy is chosen to get the pizza , he runs out of the apartment quickly and slams the front door hard. The shock jars the boulder loose and it rolled off of the diorama and onto the floor. Annie slipped on the boulder and fell into the coffee table setting off a chain of events which leads to Pierce being shot by Annie's gun. Annie pleaded with Abed to help her stop the bleeding. Before assisting her he made sure to adjust the Indiana Jones figure on the diorama which had been knocked out of place along with the boulder. In the aftermath of the events Pierce supposedly died, Annie was institutionalized, Shirley became an alcoholic, Troy's throat was severely injured and Jeff lost an arm. The Abed of that timeline declared this to be "The Darkest Timeline" and comes up with a plan to set things right. Meanwhile, the Abed of the "Prime Timeline" gets a sense that something ominous is happening ("Remedial Chaos Theory").
