CHAPTER 6-I'M BAAAACCCCCKKKKKK! Minnesota freaking ROCKED. I had the best time ever! But I missed updating, so here I am again!

14AmyChan: Actually, that was an idea I had for a one-shot….

Fanatic97: It's ok, because I came back! See, you lived.

IWANTDIPPER: Calmin' down now, calmin' down.

Living Encyclopedia: I don't think there's an 'e' on the end….

Rachealninja10: Yes, yes he has.

FanficChic2: Thank you, I did. And I really hope that you didn't die.

Migweech, guys for waiting patiently for this chapter! I think this is the longest I've gone without updating…I could be wrong on this, though. (Bonus cookies to those who know what Migweech means)

I don't own Phineas and Ferb or Gravity Falls.

A loud gasp and thud was heard from the door and Candace and the agents whipped their heads around to stare in shock at the source of the noise.

GENERAL POV

Candace leapt to her feet, putting her hands up quickly. "Dipper, no, it's not what you think!"

The boy slowly cocked his head, his eyes never leaving the secret agents behind Candace. "Isn't it?" he said, his face moving to look at her, his eyes filled with disappointment.

He shook his head and darted from the room, leaving the book he had dropped on the floor.

Candace winced and sank onto the edge of her bed, looking at the agents in worry. "What do we do?" she asked softly.

Perry sighed and looked at Pinky. "Candace, I think the only thing we can do is tell him the truth. Because if we told Monogram…it would give you away, too."

Pinky and Waddles nodded in agreement and Candace sighed, standing up and picking the book up off the floor. "You guys stay here. I'll go talk to him."

The three nodded and Candace slipped out of her bedroom, peering into each of the rooms until she found Dipper sitting in the study, his knees drawn to his chin.

She rapped lightly on the door and stepped into the room as the boy looked up, his eyebrows drawn. "Dipper? Come on, we need to talk."

Dipper scowled and sat up straight, yanking his book from Candace's hands before she could react. "What about?" he asked, tucking the book into his vest. "About how you lied to us? How Waddles lied to Mabel and me? What about, Candace? Because I want to know why."

He crossed his arms and glared at her and Candace felt herself freeze, her mouth hanging open as she stared at the disbelief and anger in the boy's eyes. "Dipper you don't…you don't get it," she finally said, lowering herself into one of the other chairs in the room.

Dipper rolled his eyes. "Oh really. How about, Waddles has lied to my sister's face, not to mention almost let us get eaten by a pterodactyl, and you just lied to your own brothers! I knew you weren't sick!"

Candace was angry now. "Want to know what you forgot? You forgot that if Waddles told you guys who he was that he'd get relocated and Mabel would be heartbroken. You forgot that you two are the most capable kids I've ever met outside my brothers and their friends and that you could have handled yourself. You forgot that Waddles was stuck in a ditch with Stan. You forgot that I'm a freaking mermaid and the reason I lied is because Perry's boss is onto me, and if he finds out I know Perry and Pinky are goners!"

She collapsed backwards into her seat, trembling, while Dipper stared at her, his face pale.

Candace shook her head and stood up, moving to the door. "Whatever, Dipper. Whatever."

Dipper stood up quickly. "Wait. Candace, I…I'm sorry. I didn't know."

Candace turned and gave him a look. The boy winced. "I…I was just…"

The girl sighed and walked back over to him. "Upset, I know. So was Phineas when he found out."

Dipper looked at her in confusion. "Phineas knows? I thought…"

Candace shook her head. "Phineas knew. But he, and everyone else but me, got their memories wiped so we could keep Perry."

Dipper shook his head slowly. "I don't get it. Why do you know?"

Candace smiled thinly and sat back down, as did Dipper. "The reason I became a mermaid, Dipper, is because of Perry's nemesis that he fights. Perry found out about me two or three weeks later, and at the same time I saw him as an agent. We didn't talk for a while, but when we did, I agreed to keep it a secret, since I had been already."

She frowned and ran a hand through her hair. "I realized a couple of weeks later that I could understand him, so that made it easier for us to talk. I kept his secret for over a year, eventually letting Pinky in on it."

Candace bit her lip and glanced out the window. "And then this whole crazy thing with another dimension happened and I found out that one of the interns that works for Perry's organization, the OWCA, knew I was a mermaid, knew that I knew about Perry. But he agreed to keep that a secret too. So it was all good for a while.

"Then a few weeks ago, I was hit with another of Dr. D's-Perry's nemesis- machines. It made me forget who I was and switch places with another mermaid. We all got back to normal, you know, but Perry's boss, Major Monogram, started to get suspicious of all the sneaking around that Carl, Perry, Pinky, and Carl's twin Carla were doing. Perry got a call this morning that Monogram put up secret, illegal cameras to try and figure out what was going on. Carl stopped him, but he was spying on you guys for a while after I left. I left because…"

"Because he can't know," Dipper finished softly, playing with his shirt.

Candace nodded. "Exactly."

Dipper pondered this for a moment, and then looked up in horror. "Oh no! Candace, we were talking about why you didn't want to go swimming. We couldn't figure it out, since we all knew that you were a mermaid so that didn't matter."

Candace shook her head quickly. "It's ok. Carl said that Major Annoying didn't have any microphones hooked up to the cameras, so he couldn't hear you."

Dipper sank back with relief. "Good. Candace I'm…I'm sorry. What are we going to do now? You're not going to have Major…whatever erase my memory are you?"

Candace sighed and shook her head again, much to the boy's relief. "No. We can't. It's hard enough sneaking around him, but memory erasing without him knowing is nearly impossible. He finds out that you know, he finds out that I know."

Dipper nodded slowly. "I can't tell Mabel, can I?"

Candace smiled gently. "Afraid not, buddy. But hey, she's already super close to Waddles, so I doubt it'll matter."

Dipper smiled and stood up, rubbing his neck. "So uh…now what?"

"Now you lay low. And maybe you could help me keep this from Major Monobrow," Candace suggested. "I'll let Carl know you know."

Dipper grimaced. "Will he be ok with that?"

Candace smirked. "He probably already knows. This room is under surveillance, and he has been keeping an eye on the video feed, haven't you Carl?" she said, directing her gaze to where she knew the hidden camera was.

Her phone rang a minute later and Candace put it on speaker. "Yeah, yeah, it's fine Candace, so long as he keeps it as much of a secret as you have," said Carl's voice.

Dipper nodded furiously. "Of course I will, sir!"

Carl chuckled. "No need for the sir, Dipper. Carl will do it just fine. Thanks guys."

Candace smiled. "Thank you, Carl!"

She hung up the phone and stuck it back in her pocket, looking at Dipper curiously. "So why did you come back home?" she asked, heading back for her room with Dipper following closely.

Dipper shrugged. "Mabel left her goggles in her bag and I offered to go back and get them, since I'm not the biggest fan of swimming. It took me a good five minutes to find them, but I got them!" he said triumphantly, pulling the goggles from his pocket.

Candace slapped her forehead. "And I was talking really loudly, so you came to investigate. Wow, some secret agent I'd make."

Dipper smiled. "Well, based on what I just heard, I'd say that you'd make a pretty good one."

Candace laughed and stepped back into her room, where Perry, Pinky, and Waddles all looked up expectantly. She glanced down at Dipper with a raised eyebrow and he smiled sheepishly.

"Sorry, I over reacted guys. Candace explained…well, everything."

The agents smiled and nodded to him, and then glanced at Candace. "I talked to Carl, and he said he won't tell Monogram," she said.

The agents looked visibly relieved and Pinky glanced at Dipper. "He won't tell anyone, will he?"

Waddles snorted something and Perry gave a chuckle, translating for Candace. "He's pretty indignant about that accusation. He won't tell, Pinky."

Candace grinned and glanced over at Dipper. "Your pig apparently trusts you a lot."

Dipper ducked his head, hiding a smile, and held up the goggles. "I should uh….get these to Mabel. See ya!"

He darted from the room, leaving Candace shaking her head, a smile on her face.

Dipper stepped into Isabella's yard, pondering everything he had just learned, in time to get soaked by a water gun that Mabel held in her hands. He looked up, spluttering. "Seriously? I brought you your goggles and this is the thanks I get?" he asked, grateful that he had left his book back in his room before coming back.

Mabel squealed. "Yay, my goggles! Give 'em here!"

Dipper rolled his eyes. "Um…no."

He darted away from her, holding her goggles just out of his sister's reach as she chased him around the yard.

Finally, he stopped about two feet from the pool and held up his hands. "Fine, fine, you can have them," he said, ignoring the giggling crowd behind him who seemed to know what was coming next.

Mabel smiled. "Thanks, Dipper."

She stepped forward and in one move, Dipper tackled her into the pool. The twins surfaced, one laughing, and one looking very upset. "You are so going to get it," Mabel growled, dunking her very wet brother underwater.

Dipper pulled her under after him and Phineas, Ferb, and the rest of the kids shrugged and joined in, Ferb dunking Phineas and Buford, of course dunking Baljeet. Isabella waited for the perfect moment, and then dunked all four boys at the exact same time.

They came up in stunned surprise, staring at Isabella. "How on earth did you just dunk all of us?" Phineas gasped.

Mabel and Dipper turned to look at the group in confusion. Isabella smirked.

"Aw, come on. I didn't get my Extreme Water Dunking Patch for nothing."

Dipper raised an eyebrow. "They've got some really weird patches."

Yes, yes they do.

So hey, new one-shot idea: Since Stacy knows about Perry now, I thought it would be interesting to have a one-shot where they figure out how to tell Candace that she knows (Staying with the story line of this series, of course). Tell me what you think!

Review please!
