A/N: Thanks for the reviews and favorites and alerts! You guys rock! I wrote this whole story in one night so it's pretty short. This isn't the last chapter, the next one is. I also forgot to put in a disclaimer in the previous chapters soooo...

Disclaimer: I do not own Codename:Kids Next Door, nor will I ever, even though I wish I did. (x4)

Previously on Key to My Heart…

"C'mon guys! Wait up! C'mon Tommy-Mobile! Speed up! Please!" Wally snickered. He was still calling it the Tommy-Mobile. Wow. Even at the age of 11, he was a dork. Wally shook his head and continued to walk. He finally made it to his house and went upstairs. He plopped down on his bed and stared at the ceiling thinking.

How did Kuki disappear yesterday then suddenly reappear in school?

Why was she talking to Abby, Hoagie, and Nigel like they never forgot each other?

Why did Abby say she's been throwing up for them for four months? And who are them?

Why didn't they show up for English?

And Wally just realized, but he didn't notice that Kuki wasn't wearing her signature over-sized green sweater and black leggings like usual. No, she wore a pink sweater, black jeans, and her converse. Why? Wally thought.

Oh Wally, you will find out soon enough.

The next day at school, Wally shared his first class with Kuki and Hoagie. He still had questions, but decided to get on Kuki's good side - maybe she'd remember him - so she'd tell him, instead of just asking.

He walked in and saw Kuki sitting in her seat next to Hoagie, but Hoagie wasn't there. Perfect. Wally thought and made his way over to his seat in front of her.

"Hey Kuki." he smiled at her as she looked up from writing on a piece of paper. She smiled back.

"Hi Wally."

"I like your sweater. It's… different." she looked down at it in confusion.

"How?"

"You usually wear a really big green sweater."

"Ohh! Well I have a little sister and she got sick and kind of threw up on them. When I went to wash them, they shrunk. So I have to wear this now." She shrugged. "Well, for now anyway."

"That's too bad. You looked cute in your green sweater." Kuki giggled and blushed.

Then Hoagie walked up and sat down next to her singing,

Wally and Kuki sitting a tree, K-I-S-S-I-N-G

First comes love, then comes marriage...

Suddenly, Hoagie's smile faltered.

Then comes an abrupt, tragic miscarriage...

Then comes blame, then comes despair, 2 hearts damaged beyond repair

By the end, he's talking as if he's scared with worry in his eyes. Kuki and Wally looked at each other blankly then back at Hoagie, who was still singing.

Wally leaves Kuki and takes the tree

He puts his head down with his eyes closed behind his goggles as he sings the last line.

D-I-V-O-R-C-E.

There was silence for a moment. Kuki broke it.

"OOOKKAAAAY! Exactly how many-" their watches blinking cut her off. Hoagie groaned.

"Not now!"

"Well Mrs. Klinker hasn't come yet, let's go!"

"Or we could just use the window." Hoagie suggested, pointing to the window on Kuki's left. She just gave him a stern look, crossed her arms and stared. "What?" Staring. "Kuki?" Staring. "ALRIGHT! Let's go before she comes!" Kuki smiled in victory.

"Where you going?" Wally asked.

"We're late for a very important… thingamabob. (OHEMGEE! THAT'S ACTUALLY A WORD!)" Hoagie answered as they got up and rushed quietly out the door. Wally contemplated following but never had the time since the teacher came in the door in the back just as the door they went through closed.

3 months later…

The next three months went the same way as the first two days Kuki had been decommissioned: the four always somehow disappearing during school when their watches flashed, then reappearing after school.

It confused Wally to no end, he never got his answers.

However, he soon would. Last week was his 13th birthday and hopefully when he was decommissioned, he would learn the secrets of the ex-KND operatives. Also, for the past week, Kuki, Hoagie, Nigel, and Abby would look at him silently, and then go back to whispering, being even quieter then they had been for the past 3 months.

Wally sat in his room in the tree house. This would be the last time he would ever see it. He thought about packing, but he remembered that the others didn't pack; they just left their things in their rooms.

Wally had an hour left before his decommissioning, so he decided to take a stroll down memory lane… while he still had them anyway.

He went to Nigel's room and rolled his eyes, but smiled, as he remembered all the times he bossed them around. And that cheesy catch phrase he always used: "Kids Next Door, BATTLE STATIONS!"

Next, he went to where Hoagie slept and chuckled as he remembered all the times he gloated that he was going to beat Hoagie in whatever video game they were playing, and lost. He was going to miss that.

After, he went to Abby's room. He's never seen her room before because she never allowed anyone but Kuki inside. He walked in and wasn't surprised to see her signature colors - red and blue - all over. Her walls were red, her carpet was blue, her sheets were red, her comforter was blue and her pillow was a combination of both. She had many magazines collecting dust on her cluttered desk (that she never used), and many posters of the boy bands she was obsessing over at the time (even though she didn't seem like the type to obsess over boy bands like a fan-girl). He smiled and shut the door.

Last, was the room he wanted to see the most, but didn't want to at the same time: Kuki's room. He walked in her door (which had neon green and neon pink stripes with her name written in perfect calligraphy in white) and was shocked to see that her room was nothing how he expected it to be. Last time he was in her room, it was all pink with those stupid Rainbow-Dorkies posters that she loved so much.

It was the complete opposite now. It was cleaner, and it wasn't pink. Her walls were in pattern stripes of a thick silver stripe, midnight blue that was a smaller stripe then the first, but still bigger small black on that came after the blue but before the silver. Her carpet was gray. He couldn't remember what color it was before - if it was another color - because her floor was always cluttered with rainbow monkeys. She had a desk in her room too, but it was organized by color with the entire rainbow monkey's she had on her floor. He noticed her favorite orange monkey was next to her second favorite green monkey.

But I thought she took it with her?

"Please don't go, Kooks!" and hugged him tightly back.

He finally released her and she went up on her tiptoes to kiss him lightly on the lips. When she pulled back to look at him, she gave him a small, sad smile and turned towards the door. Walking slowly, clutching her favorite orange rainbow monkey tightly to her chest. When she made it to the door, she turned around and waved.

She walked through the door and she was gone. He could no longer see her. She'll never remember him.

He was even more confused now.

"Wallabee Beatles." the professional voice came out of the intercom. He didn't realize how long he had been standing there thinking until he heard it.

He walked out to where the door was located; he stood in front of it, took a deep breath, and walked in.
