Jessi and Kyle fooled Cassidy into believing Jessi was dead in Kyle XY Season 3 Episode 9.
Cassidy has restarted the program that led to Kyle’s birth, thanks to the research done by the students at Latnok. Kyle doesn’t approve, but he will need to go along with it. Either that, or Cassidy will tell everybody what he did to Jessi. If he allows Cassidy to give the technology to Latnok, he’ll be allowed to go free. Now he just has to trust a blackmailer/murderer.
Jessi spots Kyle shirtless and is having difficulty keeping her hands to herself. His arms have grown, and his pectoral muscles are also expanding. Both of her hands feel nice, until he feels a shock.
Nicole doesn’t like this game they’re playing with Cassidy because he’s scary.
Josh wakes up and is all alone, but there’s a letter. He calls Andy’s voicemail and yells at it.
Jessi’s been watching cable, and she plans to find the location of the warehouse containing the formula by accessing the police’s thermal imaging scans, like how they find the people growing the weed.
Amanda comes to Kyle’s window. She thinks he’s right about Nate, who had a bunch of weird research in his dorm room. Why does she always get involved with the lying, cheating jerks? No matter what, though, Kyle’s one of the good guys, or at least he tries to be. Then she kisses him, and he gets butterflies. Now he’s confused.
Nicole volunteers to go to Latnok with Kyle to create a distraction. She visits Cassidy to talk to him about Jessi not coming home. While she does this, Kyle busts in to get data from the hard drives.
Jessi goes into Josh’s room to insult him about his dank, dark room. Based on what’s growing in a cup on his floor, she’s figured out how to stop the formula.
When he gets back home, Kyle burns Adam’s records of his experiments in order to prevent them from being done again, although he’s also burning his only real connection to the man who gave him life. He believes he saw the disc of the formula in the safe, so now he’ll have to go to Cassidy’s apartment as well. Nicole doesn’t like this new Kyle.
She’ll just have to live with it. Declan’s going to be Kyle’s wingman on this mission, and he will be picking the lock. This is bad because it’s breaking and entering, as if just entering was okay.
Kyle recognizes Cassidy’s mother’s name from Adam’s notebook. In addition to his passport, they’ve found the disc, containing the formula for the fluid. To add to that, Jessi has found the location where they are storing the formula by thermal imaging, and they can use bacteria to destroy it. Let’s see what else is on the disc. Previously, they used human embryos for this formula. Now, they’re creating clones. All the pod people are labelled 781227. They’re making clones… of Kyle. Kyle realizes he’s special because the Tragers took him in and treated him like one of their own children.
Leaving Jessi behind because she’s playing dead, Kyle is heading off to try to destroy the experiment by contaminating it. Before he leaves, he acknowledges he has feelings for her, so she kisses him after making sure there is no Nicole to interrupt, blowing out some lights in the process.
Declan has managed to patch up a video link by hacking into Andy’s minivan’s GPS. She couldn’t say goodbye to Josh, and she still can’t. So for now they’ll just say hello with a lot of miles in between them.
As Kyle’s working on contaminating the experiment, Mark comes in.
Amanda knocks on the window again. This time Jessi answers. She’s supposed to be like dead. Because Jessi can’t go anywhere, which she refuses to explain, she wants Amanda to break into Nate’s room and steal his files.
Kyle’s hanging from the ceiling and accidentally drops the syringe containing te contamination. He has to prevent it from falling with his mind.
Once Amanda breaks into Nate’s room, Jessi can hack into it on the other end. They see that there are a lot of things he’s been gathering on Kyle. Just then, Nate walks in. He phones Cassidy to tell him that Amanda and Jessi are going through his stuff.
Cassidy has ordered that everybody get out. As he’s preparing to evacuate, Mark sees a syringe fall on the ground, closely followed by Kyle. He’ll have to trust the guy who just broke in, which he agrees to do. He will buy Kyle enough time to do what he needs to do and get out.
When Kyle returns home, Cassidy is waiting for him.
There’s a reason why Jessi’s not there. She went to kick Nate’s door off the hinges. They find Sarah’s Latnok ring, which Nate stole from Cassidy. Spoiling the mood, Amanda tells her she will tell Kyle she wants him back.
Meanwhile, Kyle’s being tasered by Cassidy, who’s threatening Jessi, Amanda, and his family. So Kyle punches him through a newly created hole in the house. Just as Kyle grabs Cassidy by the throat, he tells him that his mother Grace Kingsley is his mother, too. They’re brothers.
Wait a minute. That’s it? You call that a series finale? Looks more like a cliffhanger to me. Damn ABC Family.
