WARNING: If you don't want to know what happens in this episode, don't read this photo recap!
So, last we saw Margo's dad, he was eating a corpse of Margo's mom. And now, it turns out that Margo can't remember her mother. It's because her dad ATE HER MEMORIES of her mother. That's what that was. He tells her that he thinks she's seeing him because she needs him. That's why all of this is happening.
In the abandoned house where Jules and Seth have gone to sleep, Jules has found that orb. And she's touched it. And just like Margo's dad did with Margo's mom, Jules has brought from it physical manifestations of her sister. And it appears that the orb has eaten those — causing Jules to lose the memories of her sister altogether.
Meanwhile, JD has killed that inferior version of himself (the real one, the one who came in to the house) and is now burning the body in the backyard. That's Alpha JD/Replica JD, some form of No-End House JD - but we're just gonna call him JD from now on. Because he's all that's left.
While Margo hangs out with her dad, she finally asks him why he committed suicide. Yep, turns out that he took the pills on purpose, knowing full well that they would kill him. Together they relive the trauma of her finding him dead.
And that's when Margo finds her mother's head in the trash can. She realizes that something is up and tries to get away from her father. But he's pretty insistent that they spend all amounts of time together. Trying to find a way out, Margo barricades herself in her room and tries to break a window. But...she's trapped.
Meanwhile, JD, Seth, and Jules try to come up with a plan for getting out. Realizing that there was a doorway in and there must be a doorway out, they agree to get Margo and leave. But Seth is noticing that JD's skin is peeling off. Uhm…what's that about?
Margo's dad tells her that he's probably going to get hungry again and will need to eat a person soon, and that they're going to have to work together. He tries to bang down her door, in fact, and she escapes into the closet, which turns out to be…
…a watery portal into the back yard pool! It gives Margo an escape, but her dad is hot on her trail now. He kills a dude who gets in her way, and JD, Jules, and Seth all bear witness. Margo keeps running.
Margo finds herself in the No-End House version of her local school, where she meets up with Jules. The two barricade themselves in a classroom to hide from Margo's now clearly murderous father. When he moves on, they realize they're once again in lockstep — it's time to get the hell out of here.
Seth and Margo go for a walk to look at the boundaries and edges of … wherever they are. Seth tells her that he saw all the families from foster care that he grew up with. Margo and Seth are bonding pretty seriously, and when they discover that the place has boundaries, Margo realizes that it must mean they can probaby find a way out.
Jules plays her own game of Margo-Polo, walking through the neighborhood, and is pursued by Margo's dad. As he catches up to the three of them, they run into an abandoned garage. He tells Margo he's so sorry about committing suicide, and she almost falls for it, but instead tricks her dad into falling down a deep hole in the garage floor.
When they return to the house, Dylan has turned up with his wife, Lacey. He explains that the house creates memories that eat other memories (Margo's dad, Jules' orb, etc.) Turns out the people who are standing around talking nonsense in the neighborhood are what happens if you stay too long - you lose yourself.
Before they decide to leave the house to find the way out, Seth finds JD is in the kitchen with his skin peeling off. Uh, Seth knows that something is up. He knows that JD isn't who he says he is. Team, is Seth part of the No-End House himself? As he gets back in bed with Margo, it sure looks that way.
