Mr Davenport returns to the island after being away for a while.

"I'm gonna take your word for it. Guys?" Mr Davenport says he gestures for Adam, Bree, Chase, and Leo to follow him.

"So, how have things been going here without me?" Mr Davenport ask "Amazing! I mean, uh...we miss you!" Bree says as she makes heart shape with hands.

"Don't worry, Mr. Davenport. Adam, Bree, and Chase have been doing a great job. They're amazing mentors" Sebastian says "Well, good. Maybe I can cut my trip short and head back to the mainland tomorrow" Mr Davenport says.

Harper and Perry enter the room "Not so fast, Donnie Come Lately. Things around here aren't as peachy as the droid babies say they are" Perry says "ahg and here we go!" Harper rolls her eyes.

"Really? Name one problem, Sergeant Short Set" Leo says "Well, for starters, they've been littering in the hallways" Perry says "That was you" Harper says.

"to sum up you break half the rules of this place, you are the oldest delinquent I've ever seen" Harper says.

"And you don't do anything to keep her in line?" Mr Davenport questions "I tried, but let's be honest some rules don't hurt to be broken, So I cover a lot of things, obviously with limits" Harper smirk "Did I happen to mention that I'm starting to like this girl?" Perry says.

"Great. You are my island bouncers and you are the ones breaking all the rules" Mr Davenport says "only the irrelevant ones in our...my defense" Harper says.

"Exactly, I know i didn't steal a set of key cards from our own security office, so it had to be one of your students" Perry says "or it could have been you being irresponsible, looked in the middle of the salad you stole from the cafeteria, maybe it's there" Harper says, Perry looks at her irritated.

"yeah, i mean These kids would not steal your key cards. Knowing you, you probably lost them" Mr Davenport says "Hey! I will not have my employees talk to me like that!" Perry says "You work for me!' Mr Davenport says.

"Keep telling yourself that, boss man. Don't walk away! There's something sketchy going on!" Perry says "I agree with her on that one! That there's something wrong not the part where you're not the boss" Harper says.

"what do you mean something's wrong?" Mr Davenport says "something isn't right" Harper smiles.

"Harper!" Mr Davenport says "Sorry I just don't know I still need more proof before I can tell you" Harper says "Okay!" Mr Davenport says.

......................................................................

in the Mentor's Room "So, how do you like your new living quarters?" Mr Davenport asks

"Yes they are beautiful, really look at this view and...""I asked the people who actually sleep here Harper " Mr Davenport says interrupting Harper.

She makes a pissed off face, Chase discreetly runs a hand over her back to comfort her

"I love 'em! We went from a dingy basement to paradise. It's like we won the lottery. Or finally got a parent who cares about us" Bree says

"only you guys tho!" Harper rolls her eyes "your dorm is great what are you talking about?" Mr Davenport says "sure is great, who needs windows anyway" Harper says sarcastically.

"Harper please don't start crying about a dorm" Leo says "like you did?" Chase says "I didn't cry about it!" Leo says angry.

Bob, Sebastian, and Spin walk in,"Hey, guys, what's going on?" Mr Davenport ask "Just came to say hi, see how you guys are doin', make sure everything's okay" Sebastian says.

"how thoughtful of you" Harper says suspiciously, Sebastian pretends not to have noticed her tone.

"I'm here to see how the mentors live. Ocean view, fireplace...is that a swimming pool?" Spin says.

"Hey. If Leo's a student, how come he gets to live in the mentor quarters?" Spin says "Because I'm more than a student. I'm family. Which is another way of saying...adiós" Leo says.

"Hey I'm family too, I think I deserve to be here too!" Harper says "No Harper!" Mr Davenport says.

"yeah you're not family.. family you know!" Leo says "Of course I am I am Ch..."Harper points to Chase, who makes a scared face and shakes his head, she realizes and changes the subject.

"Yeah you're right I'm nothing, I barely know you guys" Harper says getting up, everyone makes a suspicious face.

everyone except for Chase and
Sebastian leave.

"Hey, Chase. I've been meaning to ask you. Am I doing okay with my training?" Sebastian ask "Yeah. Of course. You're the best student here by far." Chase says.

"Well, I did learn from the best" Sebastian says "Say it again. But slower" Chase smiles.

"I just get so bored of using the same abilities all the time. I wish I could unlock a new one like you did. Think you could do that for me?" Sebastian asks.

"No way. Only Mr. Davenport is authorized to do that. I could get into serious trouble" Chase says.

"You're right. I shouldn't have even asked. I just didn't think it was such a big deal. I mean, I thought we were best friends" Sebastian says "We are!"Chase says in a desperate tone.

"Don't worry about it. It's totally cool" Sebastian says "Wait. I'll do it. But you can't tell anyone" Chase says.

"Don't tell anyone what?" Harper appears behind Chase with her arms crossed.

"Nothing sis!" Sebastian says, "Chase!?" Harper says "uh..don't tell anyone...that.." Chase thinks.

"That you two are dating" Sebastian says "did you tell him!" Harper smacks Chase on the arm "no...I mean...what!?" Chase tells Sebastian.

"you guys don't whisper as low as you think, and also i saw you two together last week" Sebastian says.

"Oh great, now its gone" Harper shakes her head "don't, calm down he won't tell anyone, we're best friends now!" Chase smiles excitedly "Oh you are?" Harper questions.

"We really are best friends!" Sebastian says "Yeah! And you're my girlfriend! My best friend and my girlfriend!" Chase says excitedly looking at the two.

"we get it man" Sebastian says "you got a girlfriend and a best friend now" Harper says "Can you say that again? I want to make it my ringtone" Chase says excited, Harper looks at Sebastian who just shrugs in confusion.

......................................................................

Harper is in the security room monitoring the cameras as usual, Perry enters the room hurriedly.

"girl we got a problem!" Perry says "what did you find?" Harper asks "the correct thing is what I didn't found" Perry says "what!?" Harper questions.

"someone stole explosives from the weapons area!" Perry says "what? There's no way this got past my security system" Harper says.

"Guess what, your security system just like you, it sucks!" Perry says "you suck the dark energy that circulates you make everything malfunction" Harper says.

"I'm serious! this is a real problem let's focus on it now cuz we still have the rest of our lives to hate each other" Perry says "what do you mean the rest of our lives!? That wasn't in the contract!" Harper says scared

"yeah maybe you'll get some time off when you retire" Perry says, Harper shakes her head confused.

"Look if because you said it's true we have to tell Mr Davenport" Harper says "I bet it was that boy you told me to watch out for" Perry says.

"Sebastian!? He actually was in that area, and did you happen to find the key cards?" Harper says "They mysteriously appeared on my desk, but while the key cards appeared the explosives were gone" Perry says, Harper thinks.

"What's on your mind" Perry says "I'd think better if you breathed lower!" Harper says.

"I'm sorry it's just that when you think it's like watching a machine full of rusty gears working" Perry says "I think the same thing when I see you walking" Harper says.

"Go find Adam, Bree and Chase! Now Terry!" Harper says, Perry goes after them.

......................................................................

In the common area Harper and Perry reunite Mr Davenport, Adam, Bree and Chase.

"What's going on?" Mr Davenport says "Someone stole explosives from the weapons area" Perry says "What?" Mr Davenport says.

"Didn't you see who went with the security system?" Chase says "that's the thing, whoever did this knew about the system and hacked it, it's someone from the island!" Harper says "No worries. All we have to do is wait for someone to explode, and boom! That's our guy" Adam says.

"Oh, I already know who did it" Perry sasy "Who?" Bree ask "Perry don't rush!" Harper says "No I'll tell who!" Perry says, Harper shakes her head.

"The creepy-looking guy. You know,
dark hair, whiney voice, always making googly eyes at you" Perry tells Bree.

"Wait. Sebastian? No, he wouldn't do that. He's my best friend. We talked about it. We're official now" Chase says "Oh yeah? official!?" Harper raises her eyebrow "uh..y-yes" Chase says.

"Well, I scanned the surveillance tape, and he's the only one that was in that area. It all adds up. First, he stole the
swipe cards. Then, he broke into the weapons area" Perry says "It all fits together" Harper says.

"wait do you agree with Perry?" Adam questions "miracles do happen, Chase has a best friend I think we're in miracle season" Harper says in a irritated tone.

"Do you think Sebastian would do

that?" Chase asks "I honestly don't see anything to prove otherwise" Harper says seriously, Chase looks at her worriedly.

Sebastian approaches "There's the perp right there! Hey! Where ya headed, Sebbie? Out for a stroll? Little break between classes? Give me those explosives!" Perry says desperate "oh Terry take it easy!" Harper says.

"What's she talking about?" Sebastian ask "They think that you stole explosives from the weapons area" Bree says.

"What?! Why would I do that?" Sebastian ask "Don't play coy with me. I'll find those explosives. I have the nasal cavity of a bomb-sniffing dog. Literally. That's what I get for saving a few bucks on a nose job in New Guinea" Perry says "I spent a lot of time with her this woman has
some dark stories" Harper says.

"Look, let's just all go down to the weapons area and figure out what's going on" Mr Davenport says.

......................................................................

in the weapons area, everyone enters and observes the room full of explosives that Perry and Harper claim to have been stolen.

Harper leans against the wall quietly, she holds a tennis ball in her hand for some reason.

"See? What'd I tell ya? The explosives are...." Perry says confused when seeing the explosives "Exactly where they're supposed to be" Mr Davenport says "But it's impossible. They were gone!" Perry says.

"Yep, and so were the dinosaurs. But through the magic of cinema, we can see them again" Bree makes fun of Perry "This is fishy. Somebody took these and put them back" Perry says.

Harper starts bouncing the tennis ball on the floor "Oh stop Terry, what idiot would do that?....oh wait maybe one of you guys would because you guys are being pretty silly right now" Harper says snatching the ball out of the air, Sebastian frowns at her.

"What are you saying?" Mr Davenport says, Harper approaches and throws the ball towards the explosives

"NO!" everyone screams scared, but the tennis ball she threw only revealed that the explosives present there were holograms.

"come on!, how crazy do you think I am?" Harper says "Enough to blow us all up with a tennis ball!" Bree says.

"So indeed the explosives are gone" Chase says "I told you guys, explain it now!" Perry tells Sebastian "nothing proves it was me" Sebastian says.

"he's right Terry, we have no proof" Harper says "sister, you think it was me, why would I do such a thing?" Sebastian says, Harper nods "better not make me say why" Harper says seriously.

"Harper you're overreacting" Chase says "I'm not accusing him, I'm just saying facts, which ironically point to him, but relax, it's just a funny fact, right?" Harper tells Sebastian "Exactly" Sebastian says in a not very friendly tone.

Everyone leaves, Harper goes after Chase.

"hey! Chase I know what you're thinking" Harper says "it wasn't him!can't be" Chase says worried "well..you know what they say...love is blind...that's what's happening to you right now with Sebastian" Harper says, Chase rolls his eyes.

"Why don't you trust him?" Chase questions "I don't know, he has suspicious behavior, and he knows about Krane" Harper says "yeah because I told him" Chase says.

"you what?" Harper says "He's my friend!" Chase says "Chase, don't do that.. don't jump in!" Harper says, Chase looks at her seriously.

"Chase, trust me! please!" Harper says, Chase nods "Of course I trust you" Chase says and leaves.

......................................................................

Chase tries to take Harper's advice, but Sebastian pressures him with best friend talk and Chase surrenders, unlocking Sebastian's new bionic abilities.

Perry and Mr Davenport are trapped by the explosion that happens in the Hydraloop.

......................................................................

Chase and the rest gather in the common area.

"What's going on?" Chase ask "There was an explosion in the hydraloop tunnel" Bree says "yey we found the explosives!" Harper says pretending to be excited

"Great mission accomplished!" Adam says walking out "Adam!" Bren calls him back.

"Okay. Bree, go check the weapons area and the academy to see that everyone is here, and that no other weapons are missing" Chase says, Bree super speeds away.

"Harper we need to put this place on lockdown until we figure out what's going on" Chase says "It's all ready just activate" Harper says fiddling with the cyber desk.

"Adam, Where's Mr. Davenport?" Chase ask "He went back the mainland" Adam says "Well, get him on the phone and tell him what happened" Chase says.

He speaks over intercom "Attention, students. Remain where you are. The academy is on lockdown. I repeat: the academy is on lockdown. This is not a drill" Chase says.

Harper looks at Chase like she expects him to say "you were right" but it's too early for that, he just looks at her with a "maybe you're right" look.

Bree super speeds back into the common area "all the students are
here, and apparently no other guns were stolen" Bree says "Yeah, Mr. Davenport's not answering" Adam says.

Harper stares at Chase with her arms crossed "This is crazy! Do you really think that one of our own students would blow up the hydraloop tunnel" Chase says "not just any student" Harper says.

Sebastian is revealed to be on the other side of the room "You are very smart sister!" Sebastian says.

......................................................................

"Sebastian? What are you doing?" Chase says "Is it not clear? I'm turning on you" Sebastian says.

"I'm taking my family back" Sebastian says "I thought we were your family" Chase says "No. Families fight together for what's right. At least that's what my father believed before you took him out" Sebastian says

"He never believed it, you didn't even know him" Harper says "Your father? Wait, how does he know about Krane?" Bree ask.

"Well, my buddy Chase told me all about him. He told me all sorts of things" Sebastian says "Oh, great. Did you also tell him I've been wearing his shoes?" Adam says.

"I always wondered where we came from. Luckily, Chase put the pieces together for me" Sebastian says.

"Sebastian, Krane was..."My father fought for what he believed: that bionic humans are superior. And when his beliefs were challenged by a non-bionic human like Davenport, he fought back" Sebastian says.

"I told you he's not worth fighting for, he wasn't what you think I know...""You're a traitor! You couldn't stand the fact that he was superior to you and you turned against him, you could have become one of us if you had joined him, but no, you dishonored our father" Sebastian says interrupting Harper.

"that's not what happened" Harper says "Oh no? You abandoned your father and joined the people who wanted him dead and you are still helping to imprison your family, you are atraitor!" Sebastian says.

"and you are just like him" Harper says with anger "And that's why I'm gonna carry on his legacy. See, you took away our leader and tried to pretend like nothing ever happened. I think it's time for a little payback" Sebastian says.

"Look...if this is really about the
shoes, you can have 'em back" Adam says.

Sebastian presses a button on his watch and a live feed of Mr Davenport and Perry pop up on the screen behind Adam, Bree, Chase and Harper.

"Mr. Davenport!" Bree says "You destroyed my father. Now you get to watch me destroy yours" Sebastian says "Sebastian No!" Harper says.

Sebastian presses another button on watch and the other end of the hydraloop tunnel explodes "No!" Bree says.

"I just blew up the other end of
the hydraloop tunnel...which means they should be out of oxygen in about thirty minutes. Nah, maybe less. That sweaty one's a heavy breather." Sebastian says "Guys, we have to go save them!" Bree says.

"you were right" Chase tells Harper silently, looking at the screen "told you" Harper says "i'm Sorry" Chase says looking at her upset she nods her head.

Sebastian says into comm set "Now!" He says, Lexi and Tank geo-leap from the training area to the common area besides Sebastian.

"You're not going anywhere" Lexi says "Lexi?" Bree says "Hey, teach" Lexi says.

"Tank, you're with him too?" Adam ask,Tank nods and cracks his neck with his fist.

"We took down Krane. What makes you think we can't take down the three of you?" Chase says "We were already the most powerful students here. Now that you've taught us your secrets, we know all of your weaknesses" Sebastian says

"Of course Chase made you a list" Harper says, Chase glares at her.

"It's time for the students...to school the teachers. The rebellion has begun" Sebastian says.
