Complete story — includes the ending
On the last day of the year-long experiment, Simone comes close to deducing the true nature of the neighborhood as an experimental environment in which she and her acquaintances are being studied. Everyone reveals their secrets: Jason's identity, Brent's "Best Place" objective, and Chidi having been told Simone is his soulmate. Simone and Chidi discover the scoreboard identifying them, Brent, and John as test subjects. In a last-ditch effort to earn the humans points, Michael allows Brent to fall into a sinkhole, hoping the other three will unite and rescue him despite his flaws. However, only Chidi attempts to save Brent; John and Simone decide Brent is not worth saving, and flee the neighborhood. Chidi declares that he believes that they are in the Bad Place; in a final gamble to shock Brent into re-evaluating himself, Eleanor and Michael pretend that this is true, and inform them they will now be transferred to the "real" Bad Place. Brent still cannot accept that he is not a good person, but just as the experiment ends, he begins to apologize to Chidi.
