Author's Note: Hey everybody! Bet you're all just dying for that mind-boggling twist in the mystery *wink*! The reveal is so predictable (and so soon in the story) that I didn't even bother putting this under the "Mystery" category. Sir Arthur Conan Doyle I am not, sadly... But anyway, as you know, this is just a fan work and I do not own Codename: Kids Next Door, blah blah blah! Enjoy chapter 3 of OPERATION: D.O.L.L.S!

It didn't take too long for Numbuhs 4 and 5 to rejoin their teammates. They burst through the door eagerly, before finally pausing to catch their breaths.

"So…what…did…you…find?" Numbuh 4 panted.

"Numbuh 2, if you would explain please." Numbuh 1 ordered.

Numbuh 2 nodded and gestured to the large computer screen behind him. "Right. So this is the data results from the strand of hair that was found in Father's mansion..."

"Uh huh." Numbuh 5 replied as she and Numbuh 4 joined their teammates at the data base.

"It didn't match with any known Kids Next Door operative DNA, including Numbuh 3's. But the similarities were still too strong to ignore, so I figured maybe it was computer error."

"Right."

"So, look what happens when I compare this hair with that of Numbuh 3's." He displayed the the new set of data on the giant monitor and allowed his other teammates to compare.

Numbuh 4, who was never one to have a good grasp on science, just squinted at the screen confused. "Okay, so?"

"So, look how similar they are. Not an exact match, but close. Very close."

Numbuh 4 was still confused. "Meaning…?"

"Meaning that hair probably belongs to somebody closely related to Numbuh 3," Numbuh 5 caught on. "Somebody like-."

"A sister, perhaps?" Numbuh 1 finished.

There was a moment of silence in the room while Numbuhs 1 and 2 allowed their teammates to let this new information sink in.

Finally, Numbuh 4 scoffed. "No way! How could a kindergartener be capable of-?"

"Don't underestimate her, Numbuh 4!" Numbuh 2 snapped, startling his friend. "That girl is a psycho! A psycho!"

The group gave another pause to give the theory some more thought.

All of Sector V knew that a rift had grown between Numbuh 3 and her sister Mushi when Numbuh 2 revealed that Mushi had "killed" one of Numbuh 3's favorite Rainbow Monkey dolls in an act of jealousy. And although Mushi's grudge was mostly against Numbuh 2 –as she went to extreme lengths to get revenge on him for getting her grounded– there was definitely some unresolved tension between the Sanban sisters.

Whenever her friends visited her at her house, they noticed Numbuh 3 would avoid Mushi whenever and however she could. Most of the time, Mushi would retaliate by just giving them all dirty looks. But other times Mushi would actually hang on to Numbuh 3, asking her big sister to stay home and play with her. Numbuh 3, however, always came up with an excuse to leave.

"She's not sorry, she never even tried to apologize! She only wants me around when she's bored!" Numbuh 3 would say when she was ever asked about her sister, and then she would change the topic to something else. She didn't act like it, but her friends knew that the situation with her sister made Numbuh 3 upset and that, deep down, she really missed her little sister. Well, at least the old, sweet, not-crazy little sister.

So, considering Mushi's unpredictable brand of crazy and bad relationship with Numbuh 3, maybe the pint-sized psycho was capable of taking the Delightfulization schematics. But why?

"Okay," Numbuh 4 finally said. "What if she did take Father's blueprints? You think she actually plans on using them? For what? To Delightfulize Numbuh 3?" The thought was disturbing, but hard for him to believe. Sure, Mushi was crazy and jealous of her big sister, but she never expressed any desire to harm her before.

But Numbuh 2 nodded confidently. "There's not a doubt in my mind." After all, the little brat was capable of building a machine that could bring Numbuh 3's Rainbow Monkey back from the dead to seek vengeance on Numbuh 2! Surely building a Delightful-ization Machine would be easy for her twisted little brain.

"Well great," Numbuh 5 stated. "We've got a possible suspect! But that doesn't point as to where we can find her or Numbuh 3!"

Numbuh 2 glared at her. "I was getting to that." He turned back to the database and, after some various clicking and typing, a map of their town flashed on the screen titled Sector V Emergency Tracking System.

Numbuh 1 raised an eyebrow. "What is this?"

Numbuh 2 smiled proudly. "This, my friends, is how we're gonna find Numbuh 3! All I have to do is activate her tracking chip. And when we find Numbuh 3, I'm almost positive we'll find Mushi and those missing blueprints!"

With the hit of a button, Numbuh 2 activated said tracking chip and sat back in his chair, proudly folding his hands behind his head. He waited for his friends' impressed reactions….

….He didn't get them.

"What tracking chip?" Numbuh 4 asked suspiciously.

"You chipped Numbuh 3?" Numbuh 5 interrogated.

"Did you chip all of us?!" Numbuh 1 demanded.

Numbuh 2 bit his tongue. Uh-oh. They weren't supposed to know about the chips... He looked around to see that he was surrounded by his glaring teammates, all of them waiting for an explanation.

He laughed nervously. "Uhh, well, funny story. Heh-heh. Ya see, I – Oh hey look, the system found her!"

Everybody turned their attention back to the screen, where a green dot that they assumed represented Numbuh 3 blinked before an outline of a large building.

Numbuh 2 squinted at the image and its coordinates. "That looks like the old abandoned doll factory just outside of town." He and Numbuh 4 shuddered.

"Well then," Numbuh 1 said. "Let's not waste any more time. Kids Next Door: Battle Stations!"

Author's Note: In the words of Shyamalan: "Whet a tweest!" Yeah, so all of this build up to the reveal was probably not necessary, but I like it this way. The other reason I don't want this story under the "Mystery" category is because the mystery is not the focus of the story; it's going to be on the relationship between Numbuh 3 and Mushi, which didn't get any attention in the show after Mushi went nuts. Anyway, thanks so much for reading! Keep those reviews coming, I love getting feedback from readers! Chapter 4 will be up soon so keep a look out... that's when things start gettin' sooper serial! Have a lovely day!
