PART 1
After days of fixing up the Shack themselves, the construction company finally arrives to build the motel rooms, officially beginning construction of The Mystery Manor. Stan tells them to get everything done as soon as possible and goes back inside to see Soos watching the crew work, paranoid they will damage the building.
Stan asks where the twins are, and Wendy tells him Mabel was also spying on the construction crew, trying to see if any were cute. They weren't. Mabel mentions Stan telling her about the birds and bees, causing Stan to think he is loosing his mind, as he told her when she was trapped in Dipper's body three years ago.
Stan asks where Dipper is, and Mabel tells him he is upstairs staring at the blue cylinders, trying to figure out what they are. Stan looks at a calendar and realizes the twins only have six days left in town, one day spent on the doppelganger, two lost because of the Warlock, and the other five lost with the Pixie.
Dipper comes downstairs, cylinders in hand, no closer to figuring out what they are. Wendy suggests electrifying them, and Dipper asks Soos if they have the technology needed. Soos doesn't respond, still staring at the crew. Dipper mentions asking the workers if they know anything about the cylinders, which Stan vehemently refuses, forbidding the twins from telling anyone else about the cylinders.
Mabel suggests taking a break, but Dipper says they need to focus, as not fully focusing on the cylinders lost them seven days of time. Mabel grabs the cylinders from him to get a closer look, but this quickly turns into a game of keep-away, Dipper getting more furious by the second.
Dipper points out that Mabel's getting distracted and not taking it seriously is what caused a number of their delays the past week. Mabel agrees to do the 'stupid research,' making Dipper even more mad. Mabel tells him there are more important things than mysteries, then Dipper says she isn't helping anything to the case, before saying she has never solved a mystery herself, making her upset. Mabel grabs the cylinders and heads into town on her own, leaving Dipper behind.
Dipper collapses on the porch, upset at himself for letting a mystery make him hurt Mabel. Soos comes outside, asking what the fight was about. Dipper rationalizes that their apparent lack of time made him anxious and got the best of him. He mentions that they were only supposed to be in town for a day or two for Stan's 'funeral,' and that he has important stuff at home, but despite all that, he doesn't want to leave.
Wendy comes outside just as Dipper is getting to the real reason he and Mabel fought. After their first summer, no one believed him about what they saw in town, thinking it was all fake or he had lost his mind. But back then, he still had Mabel he could talk to and be believed. After their parents divorced, he lost even that. Now that the twins are back together, he has that again, but the time crunch is weighing on him, making him worried he will lose it again.
Wendy empathizes with him, telling him and Soos about a crush she had on an older guy back when she was twelve. The guy showed her what was going on around town, and 12-year-old Wendy, who was having problems making friends at the time, felt like there was someone who she could trust, even though she often felt alone. She points out that that was how Dipper felt with Mabel not being that much help, and he promises to apologize to Mabel as soon as she gets back.
Soos offers to take Dipper into town to find Mabel, but her refuses, wanting to let Mabel cool off a bit before talking to her. Soos goes back to watching the construction workers as Dipper asks Wendy who the guy was. Wendy tells him that she promised the guy not to tell anyone who he was, but then says he was a lot like Dipper.
Dipper goes upstairs to continue research, smiling all the way, a new energy inside him. He pushes the research aside and lays down on his bed, a huge grin on his face. He then realizes what he is doing and why. He starts thinking about mysteries, failing to deny what he knows to be true- his crush on Wendy is back.
On a hill overlooking town, Mabel thinks over what Dipper said to her. She knows she has done things to help, and even solved the Quentin Trembley mystery, but realizes that she has gotten Dipper into trouble that could have been avoided entirely had she handled it on her own.
Her competitive drive kicking in, Mabel decides to go into town to try and solve the one case Dipper can't. She first tries running water over them, but this does nothing. Mabel then heads to the mall. Passing a TV store with one of the cylinders in hand, it starts to glow brighter and causes the TV's to go staticy.
Leaving the mall quickly, Mabel pulls out the second cylinder and sees it is glowing brighter as well, causing her to hypothesize the cylinders can share energy. She tests this theory using the TV in the candy store, with the same results as the first time.
As she leaves the candy store, she sees Tambry watching her. Tambry calls her a weirdo and walks away, Mabel planning on testing the cylinders using Tambry's phone. Just as she is getting ready to do so, the cylinders, which she had been rubbing together, spark and send out a bolt of electricity, which hits Tambry. Tambry collapses, and a terrified Mabel picks her up and puts her on her bike to take her back to the Shack.
Back at the Shack, Dipper is panicking because Mabel has been gone for a long time... two hours. Everyone else is trying to calm him down and tell him that Mabel is fine just as she arrives. Dipper runs outside and picks up Tambry, bringing her in as everyone else freaks out, Wendy in particular. They put Tambry in the living room as Mabel explains what happened.
After several ideas of dumping her somewhere and leaving her, Soos asks what the plan is. Tambry says "Computing Memory Module out of synch. Ejecting system memory charge, please prepare a newer charge," followed by "Initializing ejection." 'Tambry' begins to levitate parallel to the ground, blue like like that of the cylinders coming out of her. A chamber in her stomach opens, blue light and wires in the place of blood an organs, a third blue cylinder floating slightly above the unconscious 'girl.'
PART 2
Soos grabs a stool as Dipper questions whether or not Tambry was a robot their first summer, which Wendy debunks. Soos comes back to get a closer look at the insides of the robot and discovers that all the robot parts are designed to look like human body parts, but blue and synthetic, causing Mabel to theorizes that it's aliens.
Dipper remembers that it called the cylinders a 'memory charge,' and questions if that's what they really are. Mabel reminds him of their battery theory, but then Wendy says that if it was a battery, the robot would have powered down by now. Wendy pulls the memory charge away from the robot, the chamber closing, the robot going back to the ground.
Mabel realizes the charges may have turned Tambry into a robot, but Dipper tells her that's ridiculous, taking all three charges, noticing the newest one is not as bright. Mabel shows him the energy-sharing trick she discovered, and the two apologize for fighting with one another.
Stan asks where they should take 'Tambry,' but Dipper then questions who they should take her to, as sooner or later, someone would notice she was missing. Soos suggests Old Man McGucket due to his skills with tech and robotics, and Stan reluctantly allows him and the twins to tell someone else about the charges.
Soos and the twins head into town as Wendy goes to tell Tambry's parents where she is, Dipper accidentally maybe hinting to Mabel about his returned feeling for Wendy. The three of them throw around theories, Dipper debunking all of them, until Soos says the other two charges could have come from other robots. Dipper admits that is a possibility before Soos gets pulled over.
At first there's nothing wrong, but then Blubs notices Tambry in the backseat. He becomes suspicious when Tambry doesn't respond, and the twins do a less-than good job of coming up with a cover story. Luckily, he's a Gravity Falls police officer, and he lets them leave without too much of an issue.
They make it to the junk yard without another problem, McGucket still his crazy old self. Once Mabel shows him one of the charges, he agrees to help them, and Soos and Dipper bring Tambry inside McGucket's 'lab.'
He takes one of the charges from Mabel as scans it with something called the Spectro-magne-chemimeter. The report doesn't recognize the compound structure of the charge. he then scans Tambry, and realizes her 'skin' is actually an epidermal layer, but he doesn't recognize that either.
McGucket suggests shocking her, which everyone agrees to, as long as it's not too much power. The first shock does nothing, so McGucket hooks the wires up to the power box connected to the power lines. Electricity flies through the room, zapping Tambry, causing her to light up blue like she did before, the power in town going haywire. For a few seconds, nothing happens. Then Tambry, or whatever she is, wakes up.
At first, Tambry thinks she is dreaming. After Mabel pokes her, she realizes that she is awake and what she thinks is happening is really happening. She then realizes her stomach is glowing and freaks out. Dipper tries to get some information out of her, but she doesn't know anything, and doesn't appear to know she was a robot the whole time.
Tambry runs out of the junkyard, and Soos and the twins quickly follow in Soos' truck, Dipper not letting up the chase even when Tambry runs through the forest where Soos' truck can't follow. They continue on foot and follow Tambry to the same cliff Mabel was at earlier in the day.
Tambry again tells them that she doesn't know anything, and Dipper finally accepts the possibility of this. Tambry questions if she is even real at all, tears in her eyes. Mabel tells her that she is real, just glowy, and she steps away from the edge of the cliff, agreeing to let the twins help her figure out just what the heck is going on with her.
Tambry and the twins turn away from each other, Tambry trying to close her stomach chamber as the twins and Soos debate how truthful she is being. A light flashes from Tambry's direction, and they turn around to realize Tambry has disappeared. Quicky searching the woods in the dying light, they find nothing, and Soos takes them back to the Shack.
After a sleepless night, the twins are back in town, searching for Tambry. Mabel questions if the charges really did turn Tambry into a robot as they are passing the place Tambry got zapped the day before. Tambry appears and picks up the phone she dropped when she got zapped. The twins confront Tambry, who says she was at home last night and walks away.
Dipper tries rubbing the charges to gether again to zap her again, but the charges just create small sparks and do nothing. After watching Tambry trip and cut her palm, Dipper admits he may have let the mystery get to his head. Mabel agrees and the two get back in the car, passing Tambry, Mabel thinking she saw Tambry's eyes glow blue for a second, before passing it off as a trick of the light.
