The day of the prom arrived and Scott went to find Virgil to ask for a lift, he was more than surprised to find his brother fixing up his tuxedo.

"Virgil, did someone ask you to go to the prom with them?"

"No, I'll probably go with Kayo when the time comes for me since we're in the same year."

"Then why the outfit?"

"I'm in the band tonight, I'll be playing the piano."

"So, how are you getting there?"

"We're all going in the band limo, organised it last month."

Scott cursed, "can Kayo and I get in with you?"

"I'd have to find out, strictly band only. Why don't you just drive your own car there? You've got a flipping Mercedes."

"Yeah but I want to arrive in style."

"What more style could you want?" Virgil ran his hands through his hair up to a point, "women like guys with a car."

"She's our sister Virg, she's seen the car before."

"Oh yeh, haha. Well just bring her in it anyway, it'll save you money."

"But you get a limo," Scott whined.

"Join the band then, but just to let you know, our guitarist is really good and I'm the pianist so I don't know where you'd fit in. Have fun tonight."

Scott tutted, "you're a jerk you know that?"

"Yeah I did, but thanks for reminding me. Shouldn't you be getting ready?"

Scott huffed and went back to his room down the corridor which he shared with a guy in his English class, "not going to prom then Dan?"

"Yeah, I'm just not rushing."

"Right, being lazy as usual basically."

"You know me too well Tracy," he stretched, "gym session then I'll get ready. See you later mate."

Scott chuckled as his friend left then he got to work in getting ready for the prom, as he laid his tuxedo out on the bed he thought about Kayo, "am I doing the right thing?"

Rosie squeaked, "Awwh you look wonderful. Blue is definitely your colour."

Kayo looked down at the sapphire dress hugging her body, "I feel so uncomfortable, nothing is hidden."

"You look amazing, now undo that hair so I can have a go at it."

"Please don't Rosie, I want my hair up."

"And it will be, just neater than that," she touched the hair curler wand quickly, "good that's ready. Hair, down."

Kayo sighed and pulled the band out letting her hair fall down her back and stop in the middle, "there."

"Ok, let's do this," Rosie grabbed a brush and began to straighten out the tangles, "Scott Tracy taking you to prom, you do know you're the luckiest girl in this school right now?"

"But why?" Kayo looked down at the scattered bobby pins on the desk.

"Because he doesn't just ask anyone, he asks those who mean a lot to him."

"Really?" Kayo smiled to herself again, she was his sister, of course she meant a lot to him, "we're just friends though, I only know him through his brother."

"That's a privilege in itself, his brothers are also gorgeous," Rosie sighed and Kayo giggled, "what?"

"Nothing, I suppose they are aren't they?"

"Uh huh. Ok, let's curl these bits then pile it on top with jewels and this clip."

"I really hope you know what you're doing?"

"Absolutely, I did this hair style for my sister and she won prom queen."

"I don't want to win prom queen, you have to dance in front of everyone."

"Shh now keep your head still and no fidgeting."

Later that afternoon Scott came to pick up Kayo, he knocked on the door and Rosie answered.

"Hey Scott," she smiled bashfully as the tall boy smiled at her.

"Rosie right?"

"Uh huh."

"Is Kayo ready?"

"Ready as she'll ever be, prepare to meet the new Kayo."

Kayo sighed and walked out into the light, she heard Scott's breath catch and smiled, "hey."

"Wow K, you look amazing."

"If I fall on you, it's because of these," she indicated the shoes and chuckled as Scott offered his hand to her, "let's get this over with."

"You'll love it Kayo, trust me," Rosie grinned, "and you look great."

"All thanks to you," she hugged her roommate quickly, "see you this evening."

"I'll leave the room unlocked," she winked at Scott who smirked.

"Yeah, unlocked. See you Rose."

Rosie watched them go then closed the door, "she is going to score."

"Sorry about that, you know she doesn't know we're half related."

Scott smiled as he wrapped his arm around her shoulders, "we have to pretend to be a couple tonight though. You do look amazing."

"Thank you, I feel so uncomfortable though. This dress is not me."

"But it's gorgeous," Scott cleared his throat, "well it looks good on you."

"You charmer bro, how are we getting there then?"

"Virgil wouldn't let me in his limo, so I'm driving us in the Merc."

"I prefer that anyway," Kayo followed him to his car, "let's face the music, in more ways than one."

Scott got into the driver's side, "all I need to do is follow the line of limos."

"You don't know the way?" Kayo belted up.

"Of course I do, I was only messing," Scott smiled and revved the engine before driving away.

"How come Virgil is at the prom?"

"He's in the band, at least you'll have us two watching your back."

"That does reassure me, I'm not going to lie."

They reached the highway and Scott stomped down on the accelerator as they overtook a couple of limos, Kayo looked across with a smirk as she spotted Virgil looking out, she laughed and Scott followed her gaze.

"Ha! He better roll down his window," Scott pressed a button on his and watched Virgil do the same, "hey bro."

"Concentrate on your driving dumbass, you have Kayo with you."

"I'm fine, see you there. We're going the right way right?"

"What do you think?"

"Good."

"Don't speed ok? You're already going too fast."

"You worry too much!" Scott turned back to the road and sped off again much to Virgil's distaste.

"He is right though Scott, don't speed or you'll get a ticket," Kayo sat back against the seat and sighed, "prom. I didn't think I'd end up here."

"Yours is still to come," Scott took the car off the highway and stopped at the traffic lights, "I'll come back for yours if you want, do what Virgil is doing?"

"You'd play the piano for my prom?"

"No, I'd make sure I was on guitar."

"Ah. Green Scott."

"Thanks, I think it's just up here. Oh, yeah."

Kayo looked ahead at the flashing lights to lead up to what appeared to be a mansion, "oh god it's like a movie."

Scott laughed and rubbed her wrist, "it's ok. I won't leave your side."

"Thanks, bro."

"Anytime."

Virgil waited outside the house for his brother to show up and smiled as the car parked up, Kayo walked up the steps followed by Scott and he smiled, "Aww sis you look beautiful."

"I feel like an idiot, I hate dresses."

Virgil kissed her cheek, "nonsense. Let's go shall we?"

"Are you all set up inside Virg?" Scott asked as he looped his arm around Kayo's.

"Yep, the rockers are on at the moment. I'm not playing yet."

Kayo gripped Scott's arm, "I'm not ready for this."

Scott held her close, "it'll be ok, pose for the photo," he kissed her cheek as the camera flashed, "ready?."

Virgil tutted, "have fun," then went over to the stage.

Scott twirled Kayo past the girls who bullied her with a smile, "care to dance honey?"

Eliza snarled, "evening Scott."

"Just dance Eliza, I'm here for Kayo," he held Kayo close to him and moved away.

"Thanks, Scott," Kayo sighed in relief as they moved away and she looked over at Virgil playing the keyboard.

"I won't let them near you tonight, I promise," Scott stroked her hair, "was this Rosie?"

"Yes, it's a bit much isn't it?"

"No, it's beautiful," Scott blushed slightly, "you look lovely tonight so don't let those girls get to you."

Kayo smiled, "thanks, Scott, you're the best brother ever."

Scott held her close as the music transposed into a slow dance, he looked over at Virgil who smirked, "your hand Kayo?"

"What?"

"Slow dance, let's show them up."

"But I can't dance."

"I'll lead, just follow me," Scott wrapped his arm around her back, "just count three."

Kayo gulped as she felt his hand at the bottom of her spine, "ok then."

Eliza waltzed with the guy she was with but glared at Scott who was laughing with Kayo as they danced, she walked past the chocolate fountain and tried to aim some of the warm goo to hit Kayo but Scott was quicker, he dodged Kayo past and bumped Eliza with his hip so that she lost her balance and brushed past the chocolate getting it all over her dress.

"What the hell Scott?!"

"I said to stay away from Kayo and me, get the message?" Scott growled and tipped Kayo back then spun her into his arms, "don't smudge it or it'll never come out."

Kayo couldn't help but laugh, "I'm beginning to enjoy myself, but can we get some air?"

"Of course," Scott smiled and looked over at Virgil who indicated to him to move things along with Kayo, "outside by the fountains good?"

"Here is lovely," Kayo sat down on the concrete and smoothed her dress out then sighed, "Scott, why did you really ask me to prom?"

"I really wanted you to be here with me."

"I'm sure there were other girls you could've asked, what about that girl from music?"

"She's in there with someone else, but I realised that you're my friend and sister, there couldn't be anyone else as good as you."

Kayo shook her head, "you didn't need to ask me."

"I love you Kayo, you're my little sister and possibly more."

"Excuse me? Scott, I'm only 18 and you're 20."

"I know, but what's the difference really?"

"We can't rush it. I love you too but I'm not ready at the moment to be so close, I still feel like a sister to you," she nuzzled her head against his arm, "I'm sorry."

Scott kissed her cheek, "it's alright, you're right I can't rush it."

"I'm still family, don't worry," Kayo smiled as he wrapped his arms around her, "shall we go back and dance?"

"If you're ready to dance, absolutely," Scott pressed his lips to hers tenderly then held his hands out to her, "come on."

Kayo licked her lips, "you know one day, I might change my mind."

"I hope so," Scott linked arms with her and they rejoined the party which was in full swing, and for the rest of the night, the two weren't disturbed by bullies or interruptions.

(Three years later)

Thunderbird 1 landed in her hanger and Scott walked back to the lounge after changing from the rescue, he yawned and collapsed onto the sofa to begin working on the report, Kayo walked around the corner from the kitchen and grinned at the eldest brother.

"Scott, I'm so glad you're home."

Scott smiled happily and caught her in his arms, "Kayo, what have you been doing whilst I've been gone?"

"Sorting our old photos out, I found the ones from your prom."

Scott laughed, "ah yes, that day."

Kayo sighed as she settled in his arms, "I'm glad I changed my mind, because I couldn't be without you now."

Scott stroked her hair, "I love you K."

"I love you too," she tilted her head back and kissed him, she closed her eyes as she felt his hand come around the back of her neck and she rubbed his leg, she broke the kiss and hummed contentedly, "thanks."

"For what?"

"Making me see straight."

Scott kissed her again quickly, "my pleasure. Oh my god what was I was wearing?"

"You looked amazing, better than most of the guys there."

Scott smiled, "it was you who looked amazing, that dress."

"Don't even mention the dress, I'm never wearing one again. I had to wear one to my prom too, although Virgil made me feel good in it."

Scott chuckled, "shame that I said you'd go shopping with Penny on Saturday then."

Kayo whined immediately, "oh Scott why would you do that?"

"You owe her apparently."

"Dammit, I hate dress shopping. I don't suit them."

"You'd be surprised, you look incredible in them."

"Don't flatter me, Carpenter."

Scott raised an eyebrow at his middle name, "well I've given out my compliments, I'm done," he turned the page to one of them sharing a kiss at the end of prom, "this one, is good."

"Yeah, we look cute," Kayo smiled as she linked hands with Scott, "you're allowed to like this one."

"Deal."

"International Rescue, we have a situation," John called down and smiled at the two on the sofa, "is this a bad time?"

Scott blushed, "what? No, it's fine John."

"Yeah, what's the situation, John?" Kayo slipped off Scott's lap, "is Shadow needed?"

"Possibly," John smiled, "and Thunderbird 1 very likely."

"FAB. Location?"

"Beach."

"Say what?" Kayo frowned.

"Just go down there and you'll see."

"John, are you even on Thunderbird 5?"

"Of course not, see you soon," John smiled and signed off.

Kayo looked at Scott with confusion, "what is going on?"

"Only one way to find out, want to join me on the beach?"

"Absolutely," Kayo took his hand and followed him down to the beach which had a line of lights leading along the path, "what is this?"

"I have no idea," they rounded the sand dune and Scott gasped, "oh god."

Kayo stopped dead, "wow."

Virgil began to play his guitar and Gordon stood with a camera ready, "re-creating prom."

Kayo rubbed tears away, "oh my god, why would you do this?"

"It's been three years since you two got together," Gordon smiled as he took a photo, "so we thought we'd do prom the right way with only the people you loved around you."

"Yep, so here's your first dance," Virgil began to play a tango and smiled, "good luck."

Scott took Kayo's hand, "my dance will be better than yours."

Kayo took a deep breath, "ok let's do this."
