WARNING: If you don't want to know what happens in this episode, don't read this photo recap!
Thanks to the communication equipment left by the late Bob Brecke and some helpful last words from Regan's father Ted, Steph has successfully decoded the Hunter language. The ETU can now translate it into English ... and vice-versa. Finnerman wants to utilize the latter to send an order ... and set a trap.
The Hunters receive a message claiming that Musa says "The Purge is upon us" and they should all gather at a hotel in rural Ohio. Musa knows that it's an ETU trap ... but how many Hunters will fall for it?
Regan meets a nice family of Hunters who don't know why Musa has summoned them to middle-of-nowhere Ohio ... and have never heard of The Purge. Regan now has further proof that not all Hunters are terrorists or villains who need to be detained ... or worse.
After Flynn meets with Emme and tells her to never tell anyone about Abby and the Hunters, Abby herself appears and tells Flynn that 'The Purge' simply involves the Hunters leaving Earth and going home. The bombings, the drugs, the lithium and the killings were all a means to this end.
Musa tells Jackson that he wants to surrender but needs to enter the hotel to make his followers surrender as well. If the ETU doesn't let him, he'll press the button and ka-boom, everyone. Finnerman allows Musa access to the hotel after he surrenders his suicide vest. What's she up to ...?
