“She’s Come Undone” is episode seventeen of season three of Mutant X.
A sunglasses-wearing Lexa enters a building at night and takes down the security guards and everyone else she encounters. Finally, she enters an office and there gets her sunglasses knocked off, showing her eyes are glazed with white. As she’s about to kill the man in the office, Lexa jolts awake in Sanctuary. Shalimar comes in to check she’s okay. Yes; just a nightmare. Shalimar sees something, though, and turns on the light. Lexa’s hands and face have blood on them. Not Lexa’s blood.
Jesse is scanning Lexa, who asks if this is really necessary. She can’t remember the last three hours and woke up covered in blood. So, yes. Lexa’s synapses are firing at an odd rate and Jesse says that Lexa never told them what the implant Eckhart implanted did. That’s a non-issue according to her. Brennan enters; it looks like Lexa took the Helix out by herself. They can reconstruct the flightpath. Lexa isn’t remaining behind.
Jesse remains behind as the others head out in the Helix. Brennan asks Shalimar if she believes Lexa’s amnesia. He’s sure he’d remember something like that and Lexa hasn’t always told the truth. They arrive at the place where Lexa was and it’s pretty trashed. Shalimar contacts Jesse. The good news is Lexa doesn’t have to worry about witnesses. Brennan says the bad news is that’s because everyone is dead. It’s pretty obvious Lexa didn’t have a nightmare.
The final person Lexa killed is a Dr Arnot. According to Jesse, a onetime head researcher at Genomex. Last worked on Project Nine with three other doctors. Lexa has found a tattoo on Arnot’s arm and says they need to leave. She knows who he worked for. They have to take down two armed alarm technicians on the way out and Lexa says there are more behind them. This was a Dominion facility. She just attacked her own people and doesn’t know why. Jesse tells them to bring Lexa home immediately and to not let their guard down.
Lexa speaks to her contact; the Dominion was supposed to have neutralised her implant. He wants her to come in; she ends the call. Then Adam’s hologram appears; she’s the last one to see him. He’d been waiting for the right time to reveal himself but couldn’t wait any longer. Lexa is not happy with him. Adam shouldn’t expect Lexa to trust him.
Project Nine, according to Jesse, allows someone to gain complete remote control over the recipient. Lexa tried leaving the GSA after what they did to her brother. This was her punishment. Jesse doesn’t think he can get it out. Adam tried to come up with a solution; 97% of the extraction scenarios ended with her death. Lexa is heading out when Jesse confronts her, and then drops barriers around her so she can’t leave. Because someone could take control of her again.
Jesse tells the other that all the project doctors have dropped out of sight. Three are left. Jesse hopes one will be able to extract the implant. Shalimar and Brennan leave for the first. Jesse speaks to Lexa. She wants the thing out. It fries her brain if that’s tried. Lexa would rather be dead than a puppet. Brennan and Shalimar find the next doctor, dead, in a breached panic room. Jesse is attempting to remove Lexa’s implant. This fails. She dies. Just a simulation.
Lexa’s contact is briefing the Dominion council. One thinks this is a threat to them, perhaps even the Creator. They want him to hand over all the information gathered, and are assigning fixers.
Lexa is trying to cut her way out when Adam appears again and tells her this is the safest place for her. Let the others handle it. Lexa thinks he gave up the right when he abandoned Mutant X. He replies he never abandoned anything. Lexa tells Adam that Mutant X doesn’t need him and she never did. All that matters, for Adam, is Lexa needs Mutant X. He pulled strings to get her inserted, not to save them, but to save her from what she was becoming. He tells her there is a small chance of removal, but it’s very risky. Jesse sees their conversation on a security monitor.
The Dominion is going to terminate Lexa. Lexa isn’t going to stay penned up and, given that she can be taken over at any time, leaving is a very bad idea. For the first time, Adam reveals himself to everyone in order to help Lexa.
