WARNING: If you don't want to know what happens in this episode, don't read this photo recap!
In Afghanistan 2009, Finnerman and Jackson find an entire army unit has been slaughtered. Initial evidence points to opium smugglers as the culprits, but we know better ...
201805
In the present day, somebody plants a bomb under Jackson's car, intended for him and his whole family as they drive home from church. Jackson gets them out of the car just in time.
201806
After Jackson tells Finnerman that he wants back on the team, she tells him to meet her at an ETU safe house in Maryland. Briggs pulls up ... and Jackson is more than a little suspicious.
201807
Finnerman was behind the car bombing and has now sent Briggs to finish the job. Jackson talks him out of it by saying he'll be no better than the Hunters if he goes through with his orders.
201808
Meanwhile, Musa's in really bad shape after the ETU attack on the hotel. His wounds aren't healing they way they should, and he's starting to get a little paranoid, rambling on about how the humans want his body and warning Abby about how there are "traitors everywhere."
201809
The Hunters line up to have their skin cut open as a demonstration of their loyalty to Musa. Only those loyal will be able to Purge!
201810
Musa isn't satisfied by the show of loyalty. He tells Abby that The Purge will be sabotaged by The Exalted, the group that sabotaged the initial escape from the Hunters' homeworld.
201811
Now on the run from the ETU, Regan and Flynn argue over whether The Purge really is an evacuation from Earth ... or, per Flynn, just another one of Abby's lies. The answer lies with the Hunters' arms dealer Viktor Karp, whom Regan tracks down by hacking the ETU's database.
201812
Regan and Flynn try to apprehend Viktor Karp outside of a medical center, but it turns out his terminally ill son Pablo was in the back of his car, not him.
201813
Regan and Flynn take Pablo to a hotel, where he reveals that he went off his leukemia meds to clean his system for a new 'treatment.' Regan remembers that Viktor took some of her blood when she was held at his compound ... is Hunter blood meant to be some radical new cure-all?
201814
Regan calls Viktor on Pablo's phone, telling him to reveal the launch site for The Purge. Viktor says he won't give the information until his son his returned to him.
201815
After Pablo suffers a seizure, Flynn and Regan decide to inject him with his 'treatment.' Is it going to work?
201816
It did for a while ... and then Pablo's face melted off. So much for the alien cure for cancer.
201817
Regan and Flynn are surprised when Viktor's car pulls up at their agreed rendezvous point and his head comes flying out the window. We would be, too.
201818
The man behind the beheading? McCarthy, of course. He claims that Musa gave him the boot and now he wants to help stop him. The deal: He'll reveal the Purge launch site to Jackson in exchange for immunity.
201819
Speaking of the launch ... "We are going home," Musa tells the Hunters as they gather in front of their ship.
201820
Back in Afghanistan 2009, Finnerman orders Jackson to execute an innocent farmer who witnessed the Hunter attack.
201821
In the present day, at the ETU safe house, Jackson enacts another execution: Finnerman's. So long, boss lady!
