  Outside, the day seems normal. In the backyard, a group of friends talk at a picnic table, Vaughn and Stew are throwing a football around, and three cheerleaders sitting at the steps are laughing. Principal Durst and Tyler talk to each other and Tyler hands her a clipboard and sticks his pen between his teeth. Inside, Lucas enters the lounge where Josie, Corrine, and Marshall sit on the couch. He tells them that “it” is ready and they can try it out this afternoon. It is a gravity sensor that they hope will detect when a wormhole is going to open and eventually allow them to control the wormhole. Josie stops them from talking, hearing someone whispering outside. The four sneak to the window and Josie swiftly pulls open the window.

      Outside, Tyler is standing against the wall, next to the window. He has heard something about a vortex but the four don’t give him the satisfaction of acknowledging what he thinks he heard. They ask him why he is eavesdropping on them to which he replies they he is just making sure that they know about their shifts for Principal Durst’s charity carwash. All of the proceeds go to a charity promoting children’s literacy. Marshall accuses Tyler of organizing the fundraiser to get onto Principal Durst’s good side but Tyler insists his service to her is not of selfish motivation. The four walk away, going to the door. They don’t really believe that Tyler has overheard anything. On his clipboard, Tyler has written “gravity device + vortex.”

      In Science, Professor Zackaryackary is teaching about camouflage; there is a chameleon inside an aquarium (not filled with water). Professor Zackary asks Stew if he knows a reason that chameleons change colors. Stew, confidently, replies that the reason is chromatophores. The class looks to Stew in surprise. Stew responds that he had a pet chameleon named Rainbow, which gets a laugh from the class. Stew goes on to say that this chameleon probably changed color (to a dark green) because it is hot, angry, or scared.
      After class, Tyler stays in the Science room. He sifts through Professor Zackary’s papers looking for an indication of what the Science Club’s secret is. He is unable to find any evidence, however. Sparks of electrical energy run though the chameleon, in the aquarium, then through Tyler. Tyler becomes transparent, allowing objects behind him to be visible through him.

  Tyler realizes that he has the ability to camouflage himself as he returns to his normal state. He hears Lucas and Marshall at the door, carrying something heavy. As Tyler begins to panic, Lucas tells Marshall that he believes they will be able to keep an accurate database of the wormhole’s gravity signature. They struggle to open the door as Tyler, still inside the classroom, looks around. He sees Josie outside through a window and concentrates. He begins to change.
      Lucas and Marshall successfully open the door and are surprised to see Josie in the classroom. Lucas asks if she was just outside. “Josie” responds that she had to turn in a paper. There is a strange accent in her voice, resembling Tyler’s speech. Marshall asks if she can help them put the machine they are carrying away before someone sees it. “Josie” looks in a mirror, on the desk, at herself. Marshall asks again and “Josie” catches on. She opens a cupboard below the desk they are in front of and Marshall and Lucas slide the machine into it. “Josie” asks if the machine has anything to do with the wormhole. Lucas responds that the machine is his gravity sensor. “Josie” doesn’t reply. Lucas, a bit annoyed, informs her that it is the thing that she helped him work on. “Josie” agrees, telling him that she forgot. Closing the cupboard, Lucas and Marshall complain about how Tyler signed them up for the first shift. Lucas makes a comment that Tyler is “such a user.” “Josie,” however, claims that Tyler is not that bad. Lucas and Marshall look at her, surprised. “Josie” continues, saying that she thinks Tyler is kind of hot. Lucas asks her since when did she start thinking that but “Josie” responds by asking Lucas if he is jealous. Lucas shrugs the comment off and he and Marshall leave the Science room. Tyler reverts back to being himself, realizing that he morph whenever he wants.
      Tyler walks down the main hall. In Principal Durst’s office, Tyler sees Corrine and Principal Durst looking over a computer on Principal Durst’s deck. She tells Principal Durst that she can’t find the carwash file and that she believes that Principal Durst’s computer has been infected by a computer worm. Corrine tells Principal Durst that she will install a firewall to help better protect the computer. As a television is wheeled in front of our camera view, Tyler changes into Corrine, knowing that the installation of the firewall will take a while.

      Outside, cheerleaders are cheering. Josie and Stew, along with others, are washing cars while Lucas is using a vacuum cleaner (he removes a sock that is clogging the Vacuum). “Corrine” walks outside, observing the events. Two boys spray each other with water and throw sponges at each other. “Corrine” sees Vaughn drying off a car; Stew is drying the car’s side. “Corrine” figures that Vaughn knows what is going on. Going up to him, “Corrine” asks Vaughn if he knows anything about Lucas’s gravity sensing device. Vaughn warns her about talking about the topic in front of Stew and that they have to keep the secret, even if they don’t always keep Vaughn informed. “Corrine” changes the topic, telling Vaughn that it is too bad that Josie is going on a date with Tyler. Vaughn seems a bit phased by the news and walks off, saying that he does not care and that Josie can date whoever she wants. Inside, Principal Durst looks outside her window at the event, looking to the car that Stew and “Corrine”stand by. Seeing “Corrine,” Principal Durst does a double take, not believing she has seen what she thought she saw, and turns to see Corrine at her desk. Principal Durst stares at Corrine, who is still at the desk, at horror. Outside, Tyler morphs into Vaughn while no one is around. Looking back outside, Principal Durst now sees “Vaughn.” Corrine asks Principal Durst if she is feeling alright. Pushing the thought out of her mind, Principal Durst responds that she is indeed alright, pulling down the blind shades, and asks how the firewall is doing.

      Josie sits down inside another car, in the back seat. “Vaughn” sits down on the opposite side. After uneasily Josie asks him how he is doing, “Vaughn” tells her that he has heard about Lucas’s gravity sensing device. Josie asks how much he knows since she was not sure if Lucas told him anything. “Vaughn” replies that he has heard enough but adds that he doesn’t understand “what all the fuss is about.” Josie tells “Vaughn” that Lucas believes that they can control the wormhole. “Vaughn,” again, says he doesn’t understand why Luccas is making “such a fuss.” Josie tells him that traveling through time is a big deal and reminds him that he has done so. “Vaughn” is stunned to hear that he has traveled in time. Josie asks him if he remembers and “Vaughn” says that that sounds like the kind of thing that he would remember. Josie points out that he is acting strange and wants to know what is wrong with him. “Vaughn” turns the question back at her, saying that there is nothing with him and asks what is wrong with her. Josie gets out of the car. She is kind of unsettled by the experience. Looking back at the car and sees Tyler step out of it, not Vaughn.

      In the lounge, Vaughn is throwing darts when Josie walks in. Vaughn is surprised to see her and comments that he thought that she’d be on her date with Tyler. Josie seems a little offended by the comment. He tells her that Corrine told him about it. Josie inquires how long Vaughn has been in the lounge; Vaughn approximates five minutes. Josie tells him that she finished talking to someone who looked like Vaughn about two minutes ago, in a car.
      Vaughn and Josie run into the Science room. Marshall is looking at the chameleon. They ask Marshall where Professor Zackary is but Marshall does not know. Josie asks if Marshall has had any weird experiences with Vaughn. Marshall says that he has not but he had one with Josie. Corrine and Lucas walk in. Corrine exclaims that Marshall can’t be in the Science room since she just finished talking to him in outside. Marshall tells them that that is impossible since Principal Durst just sent him into the Science room to get some supplies. Vaughn tells them that Corrine was just outside asking Vaughn weird questions about the wormhole; Josie adds that Corrine was also saying weird stuff about Josie and Vaughn. Corrine denies that, saying that she has not seen Vaughn all day. Josie asks if any of them have seen Tyler; none of them have. Josie tells them that a few minutes ago, she saw Tyler in the exact same spot that she saw Vaughn. They become paranoid as they wonder if there is a way that Tyler can make himself look like all of them. Corrine tells them that Marshall was chewing a pen just like Tyler does. Lucas points out that Tyler could be anyone of them at this instant.

  The group begins to question each other’s identity. Lucas says that they should question Vaughn. Josie replies that Vaughn is really Vaughn and Vaughn agrees that Josie is who she says she is. Marshall makes them stop, telling them that Tyler is playing them against each other and that it is easy to get information with so many sharing a secret. Professor Zackary walks in, rather cheerful. Josie tells him that Tyler has an ability to change his shape. Professor Zackary agrees this is a problem and, while clicking his pen, tells them that they should come up with a test question; something that Tyler wouldn’t know the answer to but they all would. Professor Zackary writes the question “What is the location of the vortex?” Marshall advises that they write their answers on paper and reveal all answers at the same time. Josie, however, realizes that if one of them is Tyler then they don’t want to say where the wormhole is. Josie comes up with a new question “What happened on October 4th, 1987?” They sit around the a desk; going left: Josie sits in front of the mirror, then Corrine, Marshall, Vaughn, and Lucas (on Josie’s right). Professor Zackary stands in front of Josie and Lucas’s position, using his hand to write against the paper.

Professor Zackary drops his pen. He retrieves it and continues to write. All finish and they pass their answers to their rights.

Knowing that they are all “the real McCoy,” they all agree that they must find Tyler and force him out of his disguise. Vaughn tells them that they must keep Tyler away from the wormhole inside Professor Zackary’s office. They all begin to head out. Professor Zackary tells them that he will move Lucas’s gravity sensing device to his office for safe keeping.
      Outside, the carwash is still in full force. Splitting up to look around, Lucas and Marshall wash a small silver car. Corrine, Josie, and Vaughn walk back to them. Marshall observes Principal Durst who begins to chew her pen. Marshall points out that Principal Durst is currently chewing her pen exactly like Tyler does. Corrine reinforces the theory by telling them that Principal Durst was acting strangely when she was installing the firewall. Principal Durst begins walking over to them, excited that they are cleaning her car. Too late to call them back, Marshall and Lucas spring into action, using the hoses to spray Principal Durst with water. After thoroughly soaking her, Principal Durst does not change. Professor Zackary comes running up, appalled by their actions. He puts his coat around Principal Durst as she demands that they all go to her office. Professor Zackary walks her inside. Lucas tries to tell her that Vaughn, Corrine, and Josie had nothing to do with it but she does not listen. Marshall mocks Lucas’s plan and adds that his gravity sensor probably won’t work either.

      Inside, the gravity sensor measures strong readings.
      Outside, Vaughn, Josie, and Corrine try to figure out who Tyler would be is he isn’t Principal Durst. Josie recalls that when they were quizzing each other, Professor Zackary took a long time to write an answer, even though he only wrote one word, and he dropped his pen. Josie figures that Professor Zackary saw Josie’s answer reflected in the mirror when he picked up his pen. The reason he wrote so slowly was because he was copying the backwards image without knowing what he was writing. The three rush to Professor Zackary’s office.
      In Professor Zackary’s office, papers are falling from the air. Looking at the gravity sensor readings, they see that the wormhole had opened. The door closes behind them, revealing a dirty Tyler. Saying “fantastic,” Tyler opens the door and walks out.

  The Science Club watches Tyler, who is sitting at the fountain in front of the school. Looking up from his book, Tyler smiles back at them. Moving away from the window, they are distressed. Lucas summerizes the result of the events, a month detention and Tyler knows about the wormhole. Professor Zackary paces, which annoys Josie, while trying to think of a solution. She points it out to him and he stops. Marshall tells them that Tyler is back to normal. Josie figures that going through the wormhole reversed his chameleon ability. Lucas, again, highlights the most important thing about what Josie said: that Tyler has been in the wormhole. Their secret is not just theirs anymore. Professor Zackary asks them if a secret is a secret if more than one person knows of it. He tells them that too many people knew about the wormhole and that it was inevitable that another would find out. He continues saying that if Tyler went into the past, a great deal of damage could have been done to the present. However, if Tyler went into the future there is no telling what is coming their way. To keep Tyler from getting back into the wormhole, Josie says that they will need Vaughn’s assistance. Corrine and Marshall agree but Marshall warns Josie that she must watch Vaughn. Lucas objects, saying that Vaughn can’t be trusted. Josie however believes that isn’t true. Lucas, presenting Josie with a dilemma, tells her that if Vaughn is back in the club than he will leave. Lucas leaves the classroom, Josie appears hurt by the decision. Marshall tells her that Lucas will be back.

  In the janitor’s residence, Josie2 appears. He tells her that Tyler knows about the wormhole and soon the rest of the school will as well. Josie2 tells him that they will have to prepare.

Episode notes:

• Janitor's secret message: "The face of a friend is their foe. A secret is discovered. One leaves."
• The wormhole is refered to as "the vortex" as well as "the wormhole" by the science club.
• The message alignment on the board was actually changed from the time before Tyler went into the wormhole and after he came back. Basically, the information was the same, the information was just rewritten.

Personal thoughts:
Why do they still call it a vortex? They know it is a wormhole.
Anyways, This episode felt incomplete. It leads into Nanotechnology so it's kind of like a part one of two.
I so don't like Tyler's character. The way he talks is rather odd too. I'm not making fun of him, I'm just saying that he sounds so overly confident. Kind of like, he intentionally talks in a softer voice but adds a sarcastic twist to it so that he doesn't sound weak, like Marshall or Lucas sometimes do.
The little thing where they all suspected each other and were all "I'm me, really" and "We should check out Vaughn" reminded me of The Crucible with the Salem witch trials.
I loved how Vaughn had to read Lucas's answer of "Pearson's nefarious experiment." It was kind of like rubbing salt in the wound of the group's distrust of Vaughn, especially since Vaughn had to read it.

Rating: 7/10

From the chalkboard (what I could read):
Chameleons
Chameleons are a type of lizard
And part of the reptile family.
Best known fact about chameleons
is the ability to change the colour
of its skin. If you look at its changing colours
You may be surprised … changes color.
Chameleons can live for as long as 10 years.
