Warning: If you don't want to know what happened in this episode, don't read this photo recap!

Ramse has arrived with Olivia. And Jones is not entirely sure whether Ramse is friendly or not. She manages to convince Cole to be careful as Jennifer who reminds them that Olivia is not someone to mess with. In her words "that's someone who's never been anywhere she doesn't want to be. "

As an extra precaution, the gang build Olivia her own private prison. Complete with electrified fence and nobody to talk to. Except, wait for it, she's about to get a few visitors.

Meanwhile, Jones pays a visit to Ramse. She's pretty tough on him until he confesses that Sam was killed. While Hannah lived, Ramse lost his son. It's enough to convince Jones that Ramse is on the level. He's ready to kill The Witness, so Jones decides to put him back on the team.

Cole goes to visit Olivia. And she tells them who she is. Remember the little girl in 1961? Raised in a box to be helpful to the 12 Monkeys? That's Olivia. Cole and Jones are a little freaked out by the revelation. And Jones orders a battery of tests on her. Turns out? She's got some seriously strong genes.

Remember when Deacon died at the end of Season 2? It was tragic like an actual Greek tragedy, getting stabbed by people in robes. Well…

Turns out, he's not dead! All this time, he's been on Titan and getting stitched up by Mallick, that bald dude who keeps trying to help Cassie.

Deacon's been having some pretty impressive hallucinations about his father. Who's mind-bendingly awful and was clearly pretty abusive.

Now Jones and Olivia have a conversation. Over a cigarette. Through an electric fence. Olivia tries to strike a deal: Jones gives her the machine and she'll give her The Witness. Could it be that they want the same thing?

Nope. After Olivia insults Jones's past and her ability as a mother, Jones puts her in the splinter machine and tortures her like crazy.

That is, until Hannah shows up and tells her mother that torturing Olivia for information isn't going to work. Jones is moved. But Cole still wants answers. He decides to sends Olivia back in time to a dark room in the basement a few months prior.

Solitary confinement, the thing that Olivia hates most, turns out to be the most effective way to get information out of her.

Meanwhile, Jennifer Goines stops by to tell Ramse she's sorry about his son. It's definitely very sweet. As he says, "What's it say about this place, that in order to be human, you have to be a little crazy."

Olivia tells the assembled team at the Compound that there's a single moment, one chance -where they can kill The Witness. Now that she's been tortured, she's willing to tell them when and how. And Ramse and Cole are going to go back and perform the mission.

After Mallick lets him out of prison, Deacon's big redemption comes in the form of finding Cassie. She may now have a real chance at escape. One thing's for sure, she's way happy to see him.

As Cole and Ramse are sent back to the Emerson hotel in 2007, Jennifer has a terrible feeling about this. She doesn't want Cole to go, but he does. It can't be that bad, right?

Well, actually. It turns out that this whole thing has been a set up between Ramse and Olivia - the plan is to go back to 2007 where Ramse is going to kill…Cassie Railly (so that she never gives birth to the Witness).
