First things first: thank you for clicking on my story. I appreciate all the views I get, so thank you.

This was originally posted on Archive of Our Own as "Open Your Eyes," a crossover involving four shows. The other shows are Uncle Grandpa, Gravity Falls, and Kim Possible. Because this site won't allow more than two shows to cross over and I didn't want to just post this to Cartoon X-Overs, I decided to do things differently.

In the original Archive version, each group from each show stays together until a certain point at the end, when they all meet. Prior to that, the viewpoint switches chapters between groups. Since I couldn't do that here, I decided to rewrite the first chapter and have four stories, one for each group. Since this is the Detentionaire story, it's going to focus solely on Detentionaire, and the story will be continued in "Open Your Eyes," which will be posted under Cartoon X-Overs. If you want to read what everybody else is doing, the other fics are "Open Your Eyes: Uncle Grandpa", "Open Your Eyes: Gravity Falls", and "Open Your Eyes: Kim Possible."

This idea was originally proposed by Dm4487 on Archive of Our Own in the comments for my other work "Total Drama: Cartoon Multiverse." I wrote this as a gift for him.

Now let's get on with the story!

2 weeks after the Hostile Takeover of Mann, Wurst and Finnwich

Life was looking up for Lee Ping.

Sure, he still had detention for the rest of the school year. And admittedly, returning to normal life after spending the past couple of months unraveling a huge conspiracy was a bit weird, especially since he kept looking around for things that seemed out of place. And the tazelwurm not coming around as much was kind of a disappointment since the lizard had grown on him as a friend and an ally.

Despite this it was still nice not to wake up worried about lizards, pyramids, or whether his mother was really a clone. Getting his real mother back had been a weight off his mind in more ways than one: not only did he have his mother back, his dad got his wife back and he ended up not being grounded any more. Put a relationship with Tina on top of that and add in that Brandy and Cam had hooked up and that Biffy and Kimmie were together, and Lee had a pretty good thing going on.

Because he wasn't obsessed with solving a mystery, Lee was able to use his homeroom period to proofread a history essay due that day while alternating between paying attention to the news and half-ignoring it. Attention was paid whenever his girlfriend was talking; when Chaz was giving out his particular combination of rumors, insults, and self-absorption, Lee tuned out and focused on his essay.

Suddenly, a video message popped up on his laptop. An unfamiliar old man grinned at him.

"Hey, kid, guess what?" the man asked. Lee quickly muted the message and closed it. He looked up sheepishly to see Mr. Langhorne frowning at him.

"Sorry Mr. Langhorne!" Lee said. "My dad hasn't quite gotten the hang of this stuff and when it's inappropriate to call."

Mr. Langhorne frowned but decided to ignore the interruption. Lee turned back to what he was doing, only for another message to pop up a minute and a half later. Thankfully, this was at the exact same time the bell rang to signal a class change.

"Really, kid? I thought you'd like to–" the old man started to say.

"Uh, sorry Dad, I'm in class right now!" Lee said testily. He shut the window, put his laptop away and headed towards his locker. As he walked there, his cell phone rang. He looked at it, saw it was from an unrecognized number, and debated whether to answer it.

After a few more rings, he picked up.

"Sorry I called you in class," the old man said.

"What do you want?" Lee asked angrily.

"Hey!" the man said sharply. "You're really gonna wanna hear this, kid. It's about Biffy."

Lee's eyes widened and he gasped.

"Now how about we talk face-to-face?" the old man said smarmily.

Lee looked around and then ducked into a nearby empty classroom. He took out his laptop and flipped it open.

"Go ahead," he said into the phone.

Seconds later, a video message from the old man popped up onscreen. The man smirked, ended his phone call, and cracked his knuckles.

"So when's the last time you heard from Biffy?" he asked.

"Why do you want to know?" Lee asked suspiciously.

The old man barked out a laugh. "Lemme guess. It was on Friday?"

"How'd you know?" Lee asked, disturbed.

"Because I kidnapped him on Saturday."

Lee gasped. "You what?"

"Calm down, kid, he's safe and sound. For now," the man said. "But if you want to get him back, you're gonna have to follow my instructions very–"

Someone threw the door to the classroom open. Acting on instinct, Lee slammed his laptop shut.

"Well, look what we have here," a familiar voice taunted. "None other than Pingy-Ping-Ping! And where are you supposed to be during your free periods?"

Lee groaned. "Detention?"

"Excellent job, Ping! Why, you're a star pupil except–wait. You're not in detention!" Barrage snarled. "Move it out, private!"

Once the door to Fort Nigma shut, Lee quickly set up Biffy's makeshift signal jammer so he could reconnect to the internet. As soon as he did, he saw the old man still there.

"Yeah, I know, right?" the old man said to someone offscreen. "It sounds crazy, but it was our only hope. So I grab the mic, and–"

Lee coughed to get the old man's attention.

"Oh! Ah, uh, hey, kid. Thought you'd given up on your pal," the old man said awkwardly.

"Not likely," Lee said. "But I'm gonna need some proof."

"You want proof?" the old man said. "HEY MINOTAUR BOY, GET OVER HERE!"

Biffy lumbered into the camera's eye. "I told you, I'm just well-built!"

"Oh yeah, you're gonna win an award for architectural design any day now, Tiny," the old man said. "This proof enough for you, kid?"

"Hey, let me see!" Biffy said, leaning down to look into the camera. "Hey! Lee! I'm here! Help!"

"That's enough outta you," the old man said, pushing him away. "Anyway, kid, I'm running out of minutes on this call, so uh, lemme dumb it down for you. We're gonna play a little game of hide-and-seek, and lucky you, you're it. Assemble a team and await further instructions. I'll call you back in an hour?"

Lee checked the time and sighed. "Fine. I'll be there."

The old man signed off.

As soon as detention ended and Lee was let out, he sprinted to the locker bank he shared with his friends. He found Cam and Holger waiting there for him.

"Yo, homeslice, how was detention?" Cam asked.

"No time!" Lee said, panting. "Biffy's been kidnapped, and–"

"Biffy? Kidnapped?" Holger squeaked.

"Whoa, is this a prank, ese?" Cam asked, scared.

"No!" Lee said. "Grab some people and meet me in the Genius Club! I have to get a team, and we need all the help we can get!"

"Whoa, hold on, what do you mean–" Cam started to ask.

"I'll explain once we're there, now go!" Lee said frantically before running off.

Cam turned to Holger. "Okay, bro, who do we get?"

"Holger say we get all our friends who helped last time!" Holger said cheerfully.

"Okay, so Brandy–" Cam began.

"Brandy?" Holger questioned. Cam shot him a sharp look. "Okay! Yes! Good! Brandy! And also the Jenny, and Tina!"

"Right!" Cam said. "But Jenny's locker is on the other side of the school from Brandy and Tina. I'll get Brandy and Tina, you get Jenny, cool?"

"The coolest!" Holger said.

"Let's go!" Cam said.

Holger and Cam took off in opposite directions.

The first ones to arrive at the Genius Club were Jenny and Holger, who ran in at the same time. Seconds after they arrived, Brandy calmly walked in.

"So, what's going on?" Brandy asked.

Before Lee could answer, Cam and Tina rushed in. Brandy rolled her eyes.

"This had better be important," she said. "I have gym in a couple of minutes."

Lee looked at everyone in the room solemnly.

"Biffy's been kidnapped."

The room exploded into an outburst of questions.

"One at a time, please!" Lee said, upset. "One at a time!"

The room quieted down.

"Tina," Lee said.

"How do you know Biffy's been kidnapped?" she asked.

"Because Biffy's been missing the past couple of days and I got a video message from an old man telling me that Biffy's been kidnapped and I'll have to get a team together to rescue him," Lee said.

Jenny shook her head, confused. "Wait, a team to rescue him?"

"I swear, I'm not making this up," Lee said. "He said he'd call me back in ten minutes."

"So what, we just wait until then?" Brandy asked.

"Ooh, Holger tell story to pass time!" Holger said excitedly.

"NO!" everyone else in the room chorused.

"Sorry Holg," Lee said sympathetically. "Any more questions?"

Cam put his hand up.

"Go," Lee said.

"Yeah, so like, we're going to team up and do what now?" he asked.

"I don't know," Lee admitted. "But we've gotta get Biffy back. Even if it means getting neck-deep in another conspiracy."

Lee's phone rang. He picked up.

"Alright, kid, you ready?" the voice on the other end asked.

"Oh yeah, we're all coming for you," Lee said.

"Show me your team," the old man said.

Lee held up the phone to showcase his team. Onscreen, the man shook his head.

"No way, only four of you," he said. "Or else you'll never see Giganto the Minotaur Boy again."

"What? Oh come on, that's totally unfair!" Jenny complained.

"Don't care. Choose four and get your butts moving. I'll call back in fifteen minutes. Oh and by the way there are three other teams, three other victims, only the team that gets here first gets their kidnappee back. So keep that in the back of your heads," the old man said.

"What?" the group gasped.

The old man ended the call. As soon as he hung up, war broke out in the Genius Club.

"Yo, I totally deserve to go!" Cam argued.

"No, Holger from school is most deserving of going!" Holger exclaimed.

"Me and Tina were a huge help!" Jenny put in. "You know, after you rescued us from being captured."

"Alls I'm saying is I was stuck at A. Nigma High, building a pyramid and then fighting to keep it from being finished while you were off doing cool things in some secret submarine base, yo!" Camillio complained. "I wanna go out and do stuff! You know, outside of school, which was still pretty cool, but, y'know, it's still school, ese."

"Didn't you get your first kiss because you weren't with us?" Jenny pointed out.

"Oh yeah!" Cam said. He giggled happily.

"Hey!" Brandy said, insulted. She sniffed. "Well, I don't want to go. My mom would ask too many questions. Although she's been really distracted lately."

"Maybe it's because–" Cam started.

"Don't say it!" Brandy said angrily. "Not one more word, Camillio Esmereldo Martinez!"

"Look, somebody's gonna have to tell Kimmie her boyfriend's been kidnapped," Lee said.

"Not me!" everybody but Holger said quickly.

"Not me!" Holger said a couple of seconds after everyone else. He slumped. "Aw. Okay. But on one condition. I go."

"Whoa, hold on, why do you get to go?" Jenny asked.

"Because they always kafloofashoop the messenger, and Holgermiester does not want to be kafloofashooped!" Holger said. "So Holger will do it, but only if he can go on the adventure!"

"Fine," Lee said. "So, me, Holger, who else?"

Cam sighed. "I guess I'll stay back here if Brandy's going to stay."

"Wow, that's almost romantic," Brandy said.

Cam grinned. "Thanks."

"Okay, Tina, Jenny, you in?" Lee asked.

"You kidding me? Of course!" Jenny said.

"I'm in," Tina said. She frowned. "But our parents will never let us go. They're already freaked out because they thought I ran away and they want me to go to therapy."

"You didn't tell them?" Lee asked, surprised.

"Oh, right, what was I supposed to say?" Tina asked. "That I got kidnapped by a giant corporation as part of a huge conspiracy but you and your friends broke me out?"

"Okay fair point," Lee conceded. "But surely you could have said something to convince them?"

"I told my mom I was studying at Tina's like super intensely because she's a good tutor and that I forgot to call," Jenny volunteered. "But I think she only bought it because she didn't want to think I ran off."

"Yeah, there's no way we'll get clearance for this," Tina said.

"Then we're just going to have to do this the Lee Ping way," Lee said.

"Ooh! Holger from school love the Lee Ping way!" Holger said.

Brandy sighed. "Remind me again, what's the Lee Ping way?"

"Wing it," Lee said.
