A Jason1 finds Jason2 at the bottom of the cellar stairs, where Daniela had pushed him before escaping with Charlie.

Since Jason2 can't tell him where they went, Jason1 brutally beats him.

As they ride down the highway with the original Jason1, Daniela and Charlie are getting bombarded by texts from the other Jason1s.

Charlie directs them to a friend's family's summer home to use as a hideout.

Charlie is overwhelmed by the idea of all these copies of his father running around his world. Jason1 tries to reassure him.

Daniela is equally confused about what their next step should be.

Jason1 compares the situation to the time after Max's death, when their lives had to start over.

After Daniela goes to sleep, Jason1 signs into his email and discovers a chat room of Jason1s.

The Jason1 staying at the Dessen home attempts to track their movements from their bank records.

He gets his phone back from Jason2 to search it for clues.

The original Jason1 informs Daniela about the Jason1 message board.

Then he shows Jason2 the Jason1 message board to show the multiplication effect of The Box.

Charlie catches up Jason1 on events in the Dessen household.

Blair arrives at the Dessen home after answering Jason1's text.

She spies Jason2's blood and the duct tape.

Jason1 attempts to get her to track the location of her car, which the Dessen family is using, but she refuses.

When she tries to run, he shoots his gun in the air.

She pretends to hand over her phone but instead pepper sprays him, grabbing his gun in the process.

Jason1 tries to explain other dimensions to Daniela and Charlie.

Daniela can't resist looking at the Jason1 message board.

She informs the other Jason1s that she chooses the Jason1 that she's with.

Jsaon1 sees motion, grabs the poker, and rushes outside.

He finds beaten Jason2 then sees another Jason bieng shot.

An armed Jason1 gets the drop on Jason1, making him drop the poker and strip.

They wrestle until two shots kill the intruder.

The gunman is Jason2. 

Realzing he's reponsible for what's happened, he lets them go.

Jason2 used Blair's tracking app to find them.

But a Jason1 had put a tracker on the Honda and others followed.

Jason2 gives back Jason1's wedding ring to him.

Jason2 left them a box of ampules and Max's urn.

He also left a recording to explain his motivation. He encourages them to find a new world.

All the Jasons are waiting at the Box warehouse, to say goodbye.

The Jasons eventually part to let them get to The Box and leave.
