Michael (Ted Danson) and Trevor (Adam Scott) finally discover how both Eleanors (Kristen Bell and Tiya Sircar) end up in the wrong place in the afterlife.

In a sneak peek for Season 1, episode 9 of “The Good Place,” Michael and Trevor explain to everyone why the good Eleanor was sent to the Bad Place while the other Eleanor found herself in the Good Place.

“We figured out what’s happened here,” Trevor says. “You two are both named Eleanor Shellstrop. The day you died you were both in Phoenix, Ariz., shopping at the same grocery store.”

Michael adds: “The real Eleanor (Sircar) was attending a conference on the death penalty and you stopped by to pick up food for a local shelter. And fake Eleanor (Bell) was there buying margarita mix and a magazine called Celebrity Baby Plastic Surgery Disasters.”

As for how real Eleanor died, Michael revealed that she actually met her demise while trying to save fake Eleanor.

“Incredibly, you both died in the same ten thousandths of a second in the same traffic accident,” reveals the Good Place architect. “Real Eleanor was trying to save fake Eleanor’s life by pushing you out of the way of the truck.”

Now that it’s clear how the mix-up occurred, Trevor is more than ready to leave the “nice, boring” Eleanor in the Good Place and take “trash bag” Eleanor to the Bad Place with him. Michael, however, just won’t let that happen, so he tries to have a bargain with Trevor.

“How about we negotiate? Maybe give you something else [instead of taking fake Eleanor with you],” Michael asks the Bad Place representative.

“What in the world could you have that we would want?” Trevor asks.

“How about a unicorn? I bet you don’t have one of those,” Michael replies.

Watch the sneak peek below to find out if Trevor would be willing to leave fake Eleanor behind in exchange for a unicorn.

Also in the episode, according to its synopsis, Chidi (William Jackson Harper) makes a connection elsewhere, much to fake Eleanor’s disappointment. Janet (D'Arcy Carden), meanwhile, shows a different side of herself.

“The Good Place” Season 1, episode 9, entitled “… Someone Like Me as a Member,” airs on Thursday, Nov. 3, at 8:30 p.m. ET on NBC.
