When Sister Krone asked the kids if they wanted to join forces, it didn’t sound much like a request…more like a threat, which the kids should imply is followed by an unspoken “…or else.” We’ve seen how crazy Sister is, so I can’t trust her as far as I can throw her, and I’m glad Emma feels the same way—both the reveal of what and where they are and Ray’s quasi-betrayal have helped her develop a healthy skepticism.
What’s interesting to learn is that Sister has a number on her neck. 12-year-old girls who meet certain criteria apparently get a choice: get shipped off with the boys, or train to become “Mamas” themselves. In exchange for not being eaten, they are given implants that stop their hearts if they ever leave the farm. In a way, they are given less freedom; some would rather be dead than never be allowed to leave.
Sister makes no bones about it: she’s willing to help them only so she can advance her career by becoming the new Mama. If the kids escape, Isabella is responsible, so helping them escape makes sense. During a late night visit, Norman and Emma get to see the tracking device monitor up close (it’s not that precise), but there’s a lot of questions Sister claims to be unable to answer. All she can say is there are humans out there not being eaten, and if they successfully escape, they’ll have to “mix in” with them.
Sister arguably gets more usable intel from the kids then they get from her; she learns that they knew about the tracking devices, where they were, and how to break them. Cut to Ray, receiving a Polaroid camera just like one I once got for Christmas, as a gift for his good service to Mama. He puts on an act about being fascinated by photography, but pointedly leaves behind the photo he took of her.
At this point I’m wondering how much Isabella suspects Ray of spying for her simply to lift any suspicion from himself, or whether she knows the camera contains parts he can use to defeat the devices. I would think so, although perhaps Ray, Norman, and Emma are the first ever truly significant threats to her control over the farm. Maybe she’s overconfident. Surely Ray knows, and will use whatever he can on that front.
As for Sister, it doesn’t take long for her to test her suspicions by searching Ray’s sleeping area. Instead of finding the camera or any other contraband, she finds a folded up note; one it would seem Ray left for her on purpose. We don’t get to read its contents, but they may be irrelevant, as Mama shows up right after she reads it with a second letter. Mama’s sayonara strongly implies it’s a letter dismissing Sister from the plant.
Did Ray play her? Will she really be gone and one less thing for the kids to worry about next week? Are there still other tactics in this chess game of their lives Isabella has yet to reveal, even to Ray? As their escape day gets moved up once again, the tension continues to mount.
