Disclaimer: Let's get this over with. I don't own Kids Next Door. There, I said it.

Transmission continued…

Numbuh Four was in his room working out his anger on his punching bag. Mashi had just made it to Numbuh Five's room and knocked on the door.

"Yo!" Numbuh Five called. Mashi assumed that was the O-K for him to open the door. So, he did so. Numbuh five was on her bed with her legs crossed reading a magazine. She looked up.

"Hey! You ready to go?" She asked.

"Actually…" Mashi closed the door behind him.

"I have something to tell you." He said. Numbuh Five put down her magazine.

"What is it?" Mashi smiled sincerely.

"The thing is…Numbuh Four offered to train me in some fighting skills." Abby raised an eyebrow.

"Oh. Ok…that's nice…I guess." She said, a little confused.

"Yeah, see…" Mashi started rubbing the back of his head as he continued…

"When I told him you were going to train me, he said something about it being better for me to train with him than with you because he was the more experienced fighter or something." Abby froze.

"Oh, really. He said that, did he?" She asked a little frustrated.

"Well, maybe not those words exactly, but he sort of implied it, ya know? Unless I heard wrong…I…"

"Oh, no. That sounds like something Numbuh Four would say." Abby said angrily. So Wally was good at hand-to-hand combat, but everyone knew that she had been designated as the best fighter in the Kids Next Door. Why? Because her sister was the best and taught her everything she knew! Besides that, she was older than Numbuh Four and she was more experienced. In over half of their missions, Numbuh Four would be one of the operatives to run away screaming like a girl when he was really afraid. And what would Numbuh Five do? Keep her cool, come up with a plan, and fight. So she took on the role of doing all of the stealthy stuff, that was only because she was not obsessed with fighting. But for Numbuh Four to say that about her when he knew he was getting rusty…

"Do Numbuh Five a favor."

"Um…sure." Mashi said, looking as innocent as possible.

"You tell Numbuh Four that Numbuh Five needs to see him in her room ASAP." Mashi bowed and kept his head down so Abby wouldn't see his evil grin.

"I'll be sure to tell him. He said. He walked out of her room and went to Numbuh Four's place. He remembered passing it back when he left Numbuh Two's room. He knocked on the door.

"Whadya want!"

"Message from Numbuh Five." Wally growled. He got up and opened his door. He stared Mashi down.

"Ya got a lotta nerve showing your face heah! Ya know I don't like you!"

"This isn't about me. Numbuh Five said she wants to see you as soon as possible." Wally slammed his door shut behind him.

"If I find out you're lying…"

"Now why would I do that?" Mashi said shrugging and smiling.

"Just shut up!" Wally said. He went to Numbuh Five's room and knocked on her door. Little did he know, Mashi was right behind him. He was as quiet as a mouse.

"It's open!" Abby called. Wally opened the door and closed it behind him. Mashi was outside the door, listening in, he knew this would be a good show.

"Um…Numbuh Five? Numbuh 202 said you wanted to see me and…"

"HIYA!" Numbuh Five cried. She came out of no where…okay, actually she came from the ceiling. She had held herself up by holding onto the walls of her room. Anyway, she flew down and body slammed Numbuh Four.

"OW! WHAT IN THE NAME OF…!"

"Not so tough now, are ya Numbuh Four!"

"Numbuh Five! What are you….AHHHH!" Abby was sitting on Numbuh Four's back and was pulling on his leg.

"SAY IT! SAY UNCLE!"

"WHAT IN THE NAME OF ALL CRUD ARE YOU DOING!" Wally screamed.

"OWWWWW!" Numbuh Five was actually hurting him.

"NUMBUH FIVE KNOWS WHAT YOU SAID NUMBUH FOUR!"

"WHAT! WHAT DID I SAYYYYY!" Wally screamed.

"OWWWW!"

"You think you're bettah than me? Well it looks like Numbuh Five's got the upper hand here!"

"What! What are you talking about! OWWWWW!"

"You know what I'm talking about!"

"Would you get off me so I can talk to you!" Numbuh Five climbed off of Numbuh Four. He put his foot down and was panting. He looked up angrily at Numbuh Five.

"Don't you give me that look!" Numbuh Five said. Wally stared at her wide-eyed.

"ARE YOU CRAZY! Why shouldn't I! You call me in heah, I'm thinkin' you wanna talk to me, and you am-smush me!"

"Ambush, Numbuh Four."

"THAT TOO!" Abby pointed a finger at him.

"Don't try to act like Numbuh Five don't know what you said. Numbuh 202 told Numbuh Five all about it and…"

"Oh! Here we go again! You actually believe that guy over me! What did he tell you!"

"Stop the Stupid Act Numbuh Four I…." Abby paused.

"Oh wait, you can't, can you?" She said softly to herself.

"What!" Wally cried. She shook her head.

"Nothing, anyway, Numbuh 202 told Numbuh Five that you think you're a bettah fightah than her!" Wally continued stared at Abby with wide eyes. He dropped his head in aggravation. Mashi got him again.

"I don't believe this." He said.

"That's right." Abby said.

"You thought I wouldn't find out and…"

"No, I thought you were smattah than this!" Wally cried angrily. He stood up.

"I could understand Kuki being brainwashed, but not you Numbuh Five!"

"What are you talking about!"

"You! I'm talking about you! Numbuh Five, I know you were trained by Numbuh Eleven! Everyone knows that! And everyone knows she was the best fightah in the Kids Next Door! But do you honestly think that I would challenge you behind your back!"

"So, you are challenging Numbuh Five!"

"No! I was speaking hippo….hepo…hipper…uh…what's the word I'm looking for? Where am saying something that could happen, but I don't really mean it…its…uh…um…starts with an L…I think…or maybe a Q?" Abby rolled her eyes and folded her arms.

"Hypothetically, Numbuh Four.."

"Hypothetically! That's it. I was speaking Hypothetically."

"Oh really?" Abby asked.

"Yes! I'm not STUPID! I know bettah! Aside from the fact that you were trained by the best fightah in the Kids Next Door, you're bigger than me and older than me and there's a good chance you're stronger than me too! You've definitely got more experience, so I know bettah than to challenge you. And even if I did challenge you, which I'm not doing, don't you think I would have the nerve to tell you face to face rather than saying it behind your back! I'm not a coward Numbuh Five! That's my opposite, not me!" Mashi was listening outside the door.

"Opposite?" He said to himself.

"What opposite is he talking about?"

"Yeah! Well, if you know you need the experience, why won't you ever let Numbuh Five train you Numbuh Four, huh!" Abby asked. Numbuh Four stood there and was about to answer when he paused. He started having flashbacks.

Flashbacks (FB):

FB1: Wally rushes into Abby's room and he's really excited.

N4: Hey! Numbuh Five! Numbuh Two just set up this cool obstacle course for me to train in! Wanna give it a go with me!

N5: Maybe later, Numbuh Five's gonna go catch some Z's baby.

N4: (dejectedly) Oh, okay then.

FB2: Abby's just coming in from shopping at the magazine store. Wally rushes up to her.

N4: Numbuh Five! Numbuh Five! Check it out! I found my dad's old boxing gloves in his garage! I could use a sparring pahtnah (partner)!

N5: Uh-uh, Numbuh Five's about to go read one of her magazines.

N4: Okay then, more fun for me.

FB3: Wally is in his room looking at his spelling book. Abby walks in, thinking Wally will be interested in what she's got to show him.

N5: Hey, Numbuh Four, Numbuh Two just gave me this Virtual Reality helmet. Wanna help me try it out?

N4: (waves her off) Later! I gotta study for this spelling test tomorrow. Mom's orders.

N5: Alright then, your loss kid.

FB4: Same scenario as Flashback 3.

N5: Hey Numbuh Four! Got a hot new Karate Kit that I ordered from my magazine! Thought you'd like to try it out.

N4: Actually Numbuh Five, I could use some help with this math stuff. Can ya help me?

N5: (a little shocked but smiles) Sure, I guess we can do the Karate thing later.

N4: I don't know about that. This multipliticashunation is pretty tough. And so is this long dividevation.

N5: (Rolls her eyes as she walks in to help him) That's, Multiplication and Division Numbuh Four.

N4: Right! What did I say?

Flashbacks end

Wally frowned.

"How am I supposed to tell her that anytime I wanted her to train me, she wanted to rest, but when she wanted me to train with her, I had something more important to do?" He thought to himself.

"Hello! Do you hear me Numbuh Four! Answer my question!" Numbuh Five said. Numbuh Four looked up at her.

"I-I…" He sighed. He felt defeated.

"I'm….sorry, alright?" Numbuh Five raised an eyebrow.

"For?" She asked.

"Everything." Wally said, even though he wasn't really sorry; he really had nothing to be sorry about. Abby sighed.

"Okay, Numbuh Five forgives…" Wally shook his head.

"NO! Wait, I'm NOT sorry! I've got nothing to apologize for! I didn't do nothing wrong!" He pointed a finger at Abigale.

"You've known me longer than that Mashi kid. He's here like, what, a day? And you automatically believe him over me! I thought you wanted to talk to me about important Kids Next Door Stuff, but you just wanted to attack me and accuse me of something I didn't do because Mashi said something to you and you believed him!" He thought about Numbuh Three, who had done the same thing. He frowned.

"You girls are all the same! I'm so outta here!" Numbuh Four cried. He made his way out of Abby's room and opened the door. He turned back to Numbuh Five.

"I would've expected bettah from you Numbuh Five. And like I said before, I didn't say nothing about taking you on behind your back. You decide whether or not you wanna believe me. Frankly, I don't care, but I'm not gonna stand heah and take crud from someone who doesn't know what she's talking about. I'm out." Wally said, walking out of her room. He slammed the door behind her. Numbuh Five stood there, shocked. She took in everything Wally told her. Did he have a point? She sat down on her bed to think about this. Mashi made sure Numbuh Four didn't see him as he left Abby's room. Once Wally was gone, Mashi made his way into Abby's room himself.

"Um…" Abby didn't move.

"Numbuh Five."

"Numbuh Five has never seen Wally that upset, but then again she did body slam him into the ground when he first came in. Maybe Numbuh Five is in the wrong." Abby said out loud. Mashi sighed.

"No, I was in the wrong. I should have clarified Numbuh Four's words before telling you anything, I'm sorry." He said.

"Huh!" Abby looked up.

"Oh." She frowned a little.

"Yeah, sure." She said. She stared at Mashi, but couldn't sense a trace of evil radiating off of him.

"Hmm."

"Um, may I ask you a question?"

"Numbuh Five guesses so."

"What was that 'opposite' Numbuh Four was talking about?"

"Huh! You heard that!" Abby cried blushing.

"You, were pretty loud." Mashi said smiling. Abby turned her head and started putting her words before her thoughts. In other words, she was talking before she could stop herself, which she would definitely regret doing later.

"Oh, man. Well…you see, on one of our missions, we ended up having to face our opposites. They were in Numbuh Four's pool some kind or way. They had codenames too, Negative Numbuh One, Negative Numbuh Two, Negative Numbuh Three, Negative Numbuh Four, and Negative Numbuh Five. Numbuh Five's opposite was kinda dorky, but anyway, Negative Numbuh Four was the leader. He was completely opposite of our Numbuh Four. He was an evil genius and he was the head of their version of the KND, only they were the DNK, the Destructively Nefarious Kids. And in their world, the Adults played and the kids did all the work."

"Really?" Mashi asked, interested. There was a kid who actually succeeded in ruling over adults? He could use that!

"Um, what did they look like?" He asked.

"Just like us, with a few minor differences. Numbuh One's opposite was a chicken. You can tell Numbuh two's opposite because he has a -2 written on his helmet." Abby said pointing to her head.

"Numbuh Three's opposite was mean, Numbuh Four's opposite actually had a gotee. Now, how you get a 10-year old kid to grow a gotee, don't ask me. And my opposite, well, I don't even want to go there."

"I see, so it was like an alternate dimension. An upside-down world?"

"Exactly!" Abby said smiling.

"Right, well, maybe I should go and smooth things over with Numbuh Four." Mashi said. Abby smiled and leaned back on her bed.

"That might be best." She said. Mashi bowed politely.

"Thanks Abby, and again, I'm very sorry." Abby waved him off.

"Aw, forget it. It's my fault anyway. Go on and get outta here." She said. Mashi smiled and left her room. He closed her door. Abby smiled after him and it wasn't until her door closed that Abby realized what she had just done. She gasped as Numbuh Four's concerns came back to her. She slapped her forehead with her hand.

"Doh! Now you've gone and done it girl! You just told him everything that….aw man!" She leaned back on her bed.

"Well, maybe he's not as bad as Numbuh Four thinks." She said to herself. Once Mashi was outside her room. He looked at his PDA, which conveniently was also a recorder. He caught all of Numbuh Five's words. He'd have to go to the Mission Computer to review that mission itself. It was a requirement for operatives to input reports on missions into the computer. He smiled and decided to rewind his PDA so he would be ready to use Abby's information later. He saw Numbuh Four heading to his room and rushed forward, heading him off.

"Numbuh Four!" Wally looked up. He growled and clenched his fists tight.

"You'd bettah get out of my way Mashi, before I do something I regret." Mashi put his hands in his pockets.

"Come on now, listen, I'm sorry. I mean, we're all friends here, right?"

"You ain't my friend! Now I'm not gonna tell ya again, move!" Mashi looked up and saw Numbuh one getting ready to go to the mission computer himself. He smield.

"Or else what Wally!"

"Huh?" Numbuh one heard Mashi and looked there way, perfect! He started walking forward to hear better.

"It's Numbuh Four to you, you have no right to call me by my name."

"Oooh, I'm sooo scared!"

"Stand aside Mashi, I mean it!"

"And you think you can call me by my name?"

"MOVE! Or else, I'm going to have to hurt you." Wally said, trying to hold back all of his urge to throw a punch at Mashi. Numbuh one heard them. The other operatives heard the argument and put their ears to their doors.

"Is that a threat? Mr. Beatles?" Mashi asked taking a step forward. Wally stepped forward too.

"It's Numbuh Four, and if you make me any angry, it won't be no threat, it'll be happening all over your face!" Wally said, holding up a fist.

"You think you can take me!"

"I don't think, I know!" Wally said. Mashi smiled evilly.

"Bring it on…Numbuh Four." He whispered. Wally's face was turning red.

"What are ya, scared?" Mashi asked.

"Don't tempt me…" Wally said. He clenched his fist even tighter and held back his right fist, ready to throw the first punch and hit Mashi with every last ounce of his energy.

Transmission Interrupted…

A/N: HA HA HA! CLIFF-HANGER! I'm so evil, but I gotta leave ya asking for more! Think Wally's gonna throw the punch? Ya gotta read the next chapter to find out. So, read and review, please and thank you!
