The episode starts with Kirsten and Cameron in Cameron’s apartment. He wakes up to find her already up, and they talk about the obvious and about her mom. They’re both glad that they don’t have to choose anymore, and continue to be happy about it in the lab elevator, though they look entirely professional when they get out.
The body of the week has a military escort, a la Admiral Decker from when Kirsten blackmailed him. The body is Commander Denise Nichols, who used to work at NASA as a mathematician. She retired in 1992 and died of natural causes in her room. The reason that she’s in the place murdered people go is that she chose the stitch cases and the answers to how are supposedly in an impregnable spare room in her house.
Linus takes a phone call from Ivy and agrees to meet her at some point.
The stitch is really foggy, proof that Linus’s oxytocin filter didn’t work. He also has one on his computer, but it doesn’t help that much. The room is voice activated with a Star Trek reference. Through the fog, Kirsten is able to read an email about terminating her mother, probably the same one Ivy saw. She bounces.
Maggie is furious with Cameron and Kirsten for how the stitch went, but Kirsten turns it around on her. Maggie denies that Jacqueline is going to die and then leaves. Kirsten tells Cameron about a set of numbers she saw in the same email. She thinks that they might be coordinates.
Kirsten and Fisher go to Nichols’ house. Fisher tries to open the door and fails. While pointing this out to him, Kirsten manages to open it. Apparently, the door has been programmed to respond to her voice as well.
She finds stitch algorithms like the ones from way back in season 1 and calls on Linus to read them. According to him, the exchange of data indicated that Nichols was either tracking Kirsten in the stitches or tracking her progress mapping the brain. He also says that she would need something more powerful than a quantum computer to narrow down the choices from potential cases to the exact case Kirsten needs at the moment. He then leaves.
Camille tells Kirsten that she’s moving out. Kirsten’s skeptical, but can’t change her mind.
Linus goes to Ivy and it doesn’t go well. She tells him that she used his password to hack Maggie’s emails and that they’re planning to kill Jacqueline. He storms out.
Kirsten and Cameron are trying to figure out the numbers. Kirsten knows that they aren’t coordinates, but doesn’t know what they are. Linus storms in a rant, but stops when he sees Kirsten. He tells them what Ivy told him. Kirsten says she already knows and they start talking about Maggie. This leads Kirsten to an epiphany. The numbers are a trajectory that Cameron and Kirsten are going to calculate. They send Linus back to the lab.
Kirsten and Cameron drive up to the super-secret facility and Cameron comes up with really bad excuses to get them in, like Kirsten’s pregnant. They aren’t needed though, because the guard asks if she’s Kirsten Clarke and then tells her Denise Nichols told him she was coming.
Cameron thinks it might be an old munitions factory, but, whatever it is, it’s where the NSA is storing her mother. Kirsten has a really sweet moment with the pod, and then her father walks in with Ivy close behind him.
Then Fisher and Maggie enter with guns drawn. This was their plan with Ivy all along. Maggie made up the story of Jacqueline being terminated to draw Stinger out of hiding.
There is a shootout and someone hits the pod. Stinger turns himself in.
Back in the lab, Jacqueline is in the corpse cassette. Kirsten asks Cameron if she can stitch. He says she can but maybe shouldn’t. She wants Stinger to help, seeing as he’s the only one that’s stitched into a live person before. Cameron is not on board
Ivy apologizes to Linus, and he seems to be understanding.
Kirsten talks to Stinger and convinces him to take an advisory role. When he agrees, she threatens him. She manages to get Cameron on board with this plan as well, which is much harder because he actually cares. Cameron threatens him too, but with Fisher.
Before the stitch, sub-bio sees something biomechanical near her brain stem. Stinger says it’s fine, so they continue.
Jacqueline’s mind rejects the neurosync, so Kirsten has to bounce. Stinger says that Kirsten and Jacqueline need to switch places. Cameron thinks he’s crazy and they get into a fight, which Stinger uses to prove his point. Cameron explains that since they’re both alive, this stitch is about the emotional energy. A burst of Kirsten’s emotional energy could wake her up. Maggie thinks it’s too risky, but Kirsten overrules her.
Before he seals Kirsten in the corpse cassette, Cameron kisses her and tells her that he loves her. She Han Solo’s him. It’s adorable.
When the stitch starts, Kirsten’s in a lot of pain. Stinger says to lower the temperature to what it would be if there was actually a corpse in there. It appears to work, but Linus says that he sees something similar to what Jacqueline had. Stinger explains that it’s a cluster of nanobots that were infused into her brain when he stitched her into Jacqueline as a child. How they didn’t notice this before I don’t know, but moving on.
This apparently means that Kirsten chose the cases. This is full of science and fiction science, but ok. The brain is stronger than a quantum computer, and Kirsten and Jacqueline can communicate telepathically through quantum entanglement. To do that, Cameron has to reopen the channel through which Jacqueline communicated the first time. She ends up in a white room alone.
Cameron tells her to focus in on all the love she has for her mother, her friends, and him. This results in a lovely montage of images, mostly of Cameron, but of almost everyone else too. Maggie, Ivy, and Stinger aren’t included.
After this, her mother appears. Cameron bounces her and rushes to get Kirsten out of the cassette and sends for his mother.
Stinger races to Jacqueline and takes her out of the tank.
Maggie tells them that Kirsten has long term memory loss and doesn’t remember the last three years, which is by far the cruelest thing they could have done.
Then everyone leaves poor baby Cameron alone and Kirsten comes over to talk to him. She remembers him from the hospital and they have a horribly heartbreaking conversation.
He leaves, and then she turns to the camera and says, “I will never forgive you for what you’re making me do to him.” WHAT? WHO IS SHE TALKING TO? WHY DOES SHE HAVE TO FAKE MEMORY LOSS? WHY CAN’T SHE TELL ANYONE? There are plenty of theories already as to who she was talking to, let me know yours.
Wow. I’m rating this episode 10/10, contingent on Stitchers being renewed. If it isn’t renewed, I’ll rate it as a series finale and not a season finale.
So it's been cancelled. This is a pretty sucky series ending, so I'm downgrading it to a 7.
