History Recap / TheGoodPlaceS4E04TinkerTailorDemonSpy

* BackupTwin: All Janets look more or less behave the same, though it is difficult for a Good or Bad Janet to impersonate the other (and presumably a Neutral Janet). When Bad Janet is revealed the group comments that they saw a Bad Janet in the transfer, which is quickly explained as a second Bad Janet to make the switch as seamless as possible.
* BigEater: Eleanor takes a giant plate of nachos away from her run-in with Chidi. She's eaten the entire thing by the time she gets back to the Soul Squad at Mindi's house.

* ChekhovsGun: Janet's failed "lie dectector" and the stages of demon growth. After Glenn is blown up, Michael explains that, when a demon experiences severe damage, they'll revert through the stages of demon growth, starting as goo before eventually returning to normal. Later, Michael suggests blowing himself up with the demon exploder, citing that he'll just remain as goo for a few months. Although he saved from going through it, the offer of this HeroicSacrifice reassures Eleanor that Michael is really him.

* LaserGuidedKarma: By stealing Good Janet's place and attempting to sabotage the experiment, the Bad Janet wound up enduring more of Brent's harassment than Good Janet did, and even suffered more from it that Good Janet would have. While this Bad Janet was advanced enough that she could impersonate a Good Janet without immediately melting, being good and helpful was still physically painful for her. She unleashes a stream of insults the minute that Jason busts her, almost looking relieved that she can be herself.

* ChekhovsGun: Derek's sex toy handcuffs get used to lock up Bad Janet.

* TakeThat: As Michael explains the life cycle of a demon, the phase just before a full-grown demon is social media CEO.

** As with his apology to Chidi, Michael does an over the top statement, then repeats it with all sincerity. This time it's "Oh. I'm very upset about this development.".

Eleanor, Michael, Tahani, Jason and Janet play a game with Brent, Simone, John and Chidi, where their ''TabletopGame/{{Pictionary}}'' drawings come to life. Chidi makes a very bad drawing of a horse, which then comes to life as a nightmarish monstrosity that runs amok through the neighborhood.

Suddenly, one of the demons, Glenn, arrives, claiming that he's defecting from the Bad Place. He tells Eleanor that Michael is being impersonated by Vicky in a Michael-suit. The gang separate and interrogate Michael and Glenn, trying to figure out if Glenn is telling the truth. Michael insists that he hasn't been replaced, but he won't remove his suit. Michael reveals his true form is that of a six-thousand-foot fire squid, and he's afraid that once the humans saw it, they would be horrified and never see him in the same way again. Janet takes out a device she claims is a lie detector, but when she uses it on Glenn, he explodes into goo. Michael alleviates everyone's concerns when he explains that this didn't kill Glenn, as his body will reform itself eventually. To prove to everyone that he's the real Michael, Michael offers to blow himself up with the goo gun. Before he can do that, Jason then restrains Janet with a pair of handcuffs Mindy used on Derek, revealing her to be a Bad Janet who has replaced the Squad's Janet when they returned Chris back to the Bad Place. He figured this out when "Janet" didn't reply with her usual "not a girl" phrase while speaking with him. Bad Janet explains that Shawn rebooted her multiple times to upgrade her so that she could be able to convincingly act helpful without exploding in on herself. Knowing what they have to do, Jason and Michael set off to rescue Good Janet from The Bad Place.

Chidi decides it's his ethical obligation to learn to draw realistic horses.

** Also, oddly enough, Bad Janet. Michael had to use an actual Good Janet for his fake neighborhood because, initially, a Bad Janet couldn't pretend to be good without literally blowing up. But thanks to being rebooted multiple times, one Bad Janet has become much craftier and manipulative, and has given a fairly convincing performance as Good Janet.

** Michael gets one for ''not'' marbleizing Bad Janet after determining she's an impostor and getting all the information they need from her. Before he'd be quite callous to the Bad Janets, marbleizing one that our Janet needed to impersonate.

* ChekhovsSkill: Their Janet had evolved substantially after being rebooted hundreds of times, enough to be able to impersonate a Bad Janet and rescue Michael in the last episode of the second season. Shawn applied the same principle to a Bad Janet, rebooting ''40 million times'' until she was able to successfully infiltrate the group and impersonate their Janet.

* NoJustNoReaction: Simone's response to Brent attempt to call Chidi his "brotha" with an affected African American accent despite Chidi not being American.

* ShoutOut: Jason expresses skepticism that Glenn is a devil, since he doesn't [[Film/TheDevilWearsPrada wear Prada]].

* TakeThat: As Michael explains the life cycle of a demon, the phase just before full-grown demon is social media CEO.

* YouMonster: Tahani calls Bad Janet one after she says she was going to tell Tahani to get an asymmetrical haircuit. [[InsultBackfire Bad Janet takes it as a compliment.]]

* BookEnds: The ending of episode 3 had a mysterious figure, who turned out to be Glenn, drive a hand car from The Bad Place. This episode’s ending has Jason and Michael drive a hand car into The Bad Place

* BackupTwin: All Janets look and more or less behave the same, though it is difficult for a Good or Bad Janet to impersonate the other (and presumably a Neutral Janet). When Bad Janet is revealed the group comments that they saw a Bad Janet in the transfer, which is quickly explained as a second Bad Janet to make the switch as seamless as possible.

* ChekhovsBoomerang: A Janet's ability to impersonate other Janets. This time, the Bad Place uses it to sabotage the new experiment.
