Charlie informs Jason2 that Daniela has gone to Ryan's apartment because Mindy sounded bad on the phone.

Jason1 attacks Jason2 when he's taking out the trash and they struggle.

Jason2 gets the advantage, eventually killing Jason1.

Ryan vaguely recognizes Daniela as one of his car-repair customers.

She has him go through his recent memories.

Daniela determines that Jason2 had been buying Ryan drinks.

She and Mindy agree to get Ryan mental-health treatment.

Two other Jason1s meet in The Box's Corridor.

They duck out different doors into Chicago, with one ending up following the other.

At home, Jason2 is wrapping up Jason1's body in his garage.

Elsewhere, one Jason1 ducks into the Village Tap to escape the other. But the other is already sitting at a booth.

So, they share beers and compare notes.

They realize how many different Jason1 their choices have created, some of whom made it to the right version of Chicago.

They both want to kill Jason2.

But all of the Jason1s on this world want to get his family back.

Worries keep Jason2 and Daniela from sleeping.

One Jason1 discovers he can't smoke in a restaurant.

Dawn, a cop in this world, arrests him when he refuses to put out his cigar.

Daniela gest suspicious when Jason2 won't let her take the Civic, which has the body of a Jason1 in the trunk.

Jason2 had forgotten that he'd promised Charlie he would show him around the University of Chicago campus.

Jason2 spots a Jason1 tailing him and tries to lose him in the library.

Daniela has gone with bolt cutters to Jason2's storage unit.

Seeing many things she doesn't understand, she finds Ryan's mechanic's uniform then gets a phone call.

Charlie realizes his father is acting strangely.

He sends Charlie to drive the car to the other side of campus, then runs into the stacks, hoping to lose that Jason1.

Jason2 chokes this Jason1 to death in a restroom.

A cop flashing his lights pulls in behind the parked Charlie.

Jason2 locks the body in a stall.

Then he runs up in time to save Charlie from the cop.

Daniela had been called to bail out the arrested Jason1.

After an involved explanation, he has her call Jason2 so she can understand there's two of them.

Then Jason1 explains to her how she can test Jason2. She traps him in a lie about a nonexistent vacation.

She and Jason1 set up a place to meet and a safe word, "Jupiter."

Jason2 tells Daniela that they're in trouble and need to flee town.

Daniela shoves Jason2 down the stairs into the basement, locking the door.

As she and Charlie are pulling away, a car cuts them off, driven by another Jason1. 

That car is struck by a car also driven by another Jason1.

Daniela and Charlie take off running.

They meet the original Jason1 at The Bean and he says "Jupiter."
