The explosion of expletives from his eldest brother were clearly audible even from where Gordon was floating in the pool. It didn't take a genius to surmise that Scott had just discovered the toffee on the chair, and probably by sitting on it.

As far as pranks went, it was simple but effective. No-one had been in the room when Gordon had slipped the small chunk of toffee, warmed in the microwave under his watchful eye and Grandma's carefully blind one, onto the seat just after dumping his mud-lathered uniform off in Scott's despairing arms. Barring Grandma, none of the island residents had any idea that the toffee hadn't just slipped out of Scott's pocket earlier a la the first incident style, and both Grandma and their ever-watchful Eye in the Sky were firmly on his team. It had been John that had struck a conversation up with Alan to keep him out of the way, after all.

Grandma's voice carried clearly from the kitchen as she hollered up at Scott about minding his language. There was the vague threat of washing his mouth out with soap in there, and Gordon could well imagine the look on Scott's face as he called an apology back down.

He suspected Scott was already sick of soap. The washing machine had been a stroke of genius, even if he did say so himself. A little bit of toffee in Scott's jean pockets wasn't even suspicious, not when toffee in his pocket had been the start of it all. Add in an unaware Alan proving him the perfect alibi, and there was nothing to even suggest it wasn't an accident. Still, there was revenge and there was cruelty, and even Gordon had limits. Virgil would get the machine repaired by the end of the day, as long as no more rescues cropped up, and Gordon wasn't about to keep crippling it.

Scott wouldn't be the only one getting suspicious if it kept breaking, and he had no plans to get Virgil on his back, especially as his older brother was clearly annoyed about having to fix it the first time. If he realised it was intentional rather than accidental, well, that would probably be the end of a squid. No, Gordon had to keep things fluid, unsuspicious. Neither John nor Grandma were providing ideas, but as long as they kept providing the means and alibis (when an innocent Alan didn't do the job for him), he had a week to prank with his brother with no fear of retribution.

Scott's toffee stash would last a week, easily. Even if he turned to it as comfort food. Gordon hoped he did; it would be much easier to pull off his plan if Scott continued to eat the stuff. He had John on Scott-watch for that exact reason. True to form, John hadn't told him where the stash was, but he had suggested where a really good hiding place away from younger brothers might be, and sure enough, Gordon had found a whole mountain of the stuff there.

It was a literal mountain. Gordon had no idea how Scott's teeth hadn't all rotted yet. His ached just looking at it.

Above him, it sounded as though Grandma had gone to investigate the cause of Scott's language, because she was still berating him for it. As tempting as it was to go up and see the scene with his own eyes, Gordon had been a prankster long enough to know that returning to the scene of the crime automatically made him suspicious. Content that Grandma had it all in hand, he rolled over onto his front and continued his laps.

He eventually left his beloved water at a call for dinner. Reluctantly, of course – the call had come from Grandma, and just because she was helping him prank Scott didn't mean she'd suddenly become a competent cook. Unfortunately, the pool was right by the kitchen, and with his grandmother standing just under the eaves, there was no way for him to pretend he hadn't heard the call.

At least none of his other Earthbound brothers were escaping, either. John was invariably munching on some dehydrated just-add-water feast above their heads, and not for the first time Gordon thought it thoroughly unfair that he had the better deal. Dehydrated food was not supposed to be better than good old fashioned home cooking.

Maybe that was why Dad had spent so much time in space. Gordon could hardly blame him.

None of them even dared to hazard a guess at the name of the concoction on their plates, but with Grandma seated firmly at the foot of the table and watching them all closely, they had no choice but to tentatively take their first bites before simultaneously reaching for large mugs of their preferred drink.

Alan mumbled something uncomplimentary into his juice, and Grandma sent him a sharp look. Virgil chose that moment to speak, and Gordon knew the timing wasn't coincidental.

"I've got the washing machine fixed," he said, sending Scott a glare. "Don't break it again."

"I don't plan to," Scott groaned in response, throwing back his squash to get rid of the taste from his latest mouthful. "I'd like to see something other than laundry this week."

"Speaking of the laundry," Grandma interrupted. "I want that chair spotless, young man."

"What chair?" Alan asked, fixing their eldest brother with a suspicious stare when he groaned. "Is one of the chairs dirty again?"

"Some toffee appears to have found its way onto the desk chair," Grandma explained. "Your brother found it by sitting in it." Virgil stiffened.

"If that washing machine experiences another death by toffee, I am not fixing it," he threatened. Scott sighed, running a hand through his hair. He looked tired, not that Gordon blamed him after that hell of a rescue. They were all tired from trudging through mud and then cleaning it off of Thunderbird Two once they got home.

"I'll handwash them," he promised. "I have no idea how toffee even got there."

"You mean it didn't fall out of your pocket this time?" Alan chipped in.

"I didn't have any in my pocket for it to fall out, Alan," Scott defended himself. Alan shrugged as though that wasn't a factor that needed considering.

"You had some in your pocket yesterday, maybe it fell out then?"

Gordon watched a look of uncertainty flicker across Scott's face, before his shoulders slumped.

"I guess that's possible," he admitted.

"You're quiet, Gordo," Virgil commented, and he looked at him.

"Huh?"

"Something wrong?" Toffee incident(s) forgotten, Scott was straight into smothering older brother mode. Annoying, except when it was useful. He poked at the concoction on his plate dubiously.

"I don't think I feel too good." It was hardly a lie; he loved his grandmother but he could also really do without her cooking.

"Try a few more mouthfuls, dear," the wicked witch of the kitchen said. "Some good food should help."

"I don't see that here," Alan muttered under his breath, but Gordon gave her a patented Believable Fake Smile and prodded at his plate some more, reluctantly forcing himself to eat a few more bites. She beamed at him, and he gave her a polite smile back, all too aware that his alliance with her was just as tentative as his alliance with John, and therefore relied on keeping her sweet.

Which, right now, meant consuming as much of her latest cooking disaster as he could stomach.

Scott – oldest, bravest, sacrificial lamb on behalf of his brothers – was the first to cave, begging off on a full stomach and a reminder of the jeans he now had to handwash. His plate was mostly empty, although when he'd managed to stuff that much in his mouth Gordon had no idea, and after a moment of silent contemplation on Grandma's side he was given permission to wash his plate up and leave.

Gordon loved it when his brothers made things so easy for him. He shoved the concoction on his plate around for another few minutes, occasionally taking mouthfuls, before putting his cutlery down with a groan.

"Sorry, Grandma, I don't think I'm going to eat any more." She peered at him closely before standing up and walking around the table to get to him. He wasn't expecting her to press a hand to his forehead, and jumped when she made contact.

"Well your temperature's normal," she mused, and inwardly he groaned. Please let me leave the table, Grandma! "But if you're really not up to eating, off to bed with you." Yes! Grandma you are The Best!

"Sorry," he said out loud, standing up slowly and picking his plate up. "I'll just get this cleared up-"

She whisked it out of his hands.

"I said bed, young man," she scolded. "I can do your dishes for one evening, but I'll be up to check on you once I'm done and I don't want to see you out of bed." She steered him towards the stairs and, once out of sight of his brothers, gave him a wink. He grinned back, before starting the climb to the bedrooms – and, more importantly right now – Scott's toffee stash.

Having Grandma for an ally made a real difference to pranking.

He kept up the pretence all the way to his room, just in case he met Scott. He didn't, but Gordon had long since learnt not to take that for granted. Shutting himself in his bathroom, he called John.

As predicted, the ginger was munching away on cardboard-flavoured food that Gordon would do a lot to have instead of his grandmother's cooking.

"Scott's in the laundry room," his brother told him without preamble. "Brains and MAX are in their lab, and Grandma has Virgil and Alan pinned in the kitchen." Not for the first time, Gordon was pleased Kayo was off doing agent-y things with Lady Penelope for the week. Her allegiance was harder to secure than John's, and even when he had it she was liable to tell on him to Scott or Virgil at any time. Sneaking past her was also much harder. "I'd estimate you have five minutes before any of them move from their current locations."

"Roger that," he grinned. "It'll take me two."

Scott's hiding place was brilliant in its simplicity. It was both somewhere no-one, not even Gordon, would think to look, but so easily accessible that the chances of being caught in the act of retrieving some were close enough to nil – barring John and his All-Seeing Eyeness. Unfortunately for Scott, now that John had Not-Shared it with Gordon, those same factors made it child's play to steal from.

Gordon was careful not to take too much – Scott was the sort of person to know exactly how much toffee he had, and would very quickly put two and two together if toffee kept appearing in places he didn't remember having any and he noticed it vanishing from his stash. Besides, too much and the game would be up before it even began. He took a couple of small pieces from near the back, ones with identical wrappers to many others. Scott would have to be particularly observant and calculating to notice the disappearance of those.

Prizes obtained, he found his way back to his room and connected with John again.

"Grandma's on her way up," his brother warned, and despite having Grandma as an ally, Gordon figured it would be best to throw on some pyjamas and slink into bed regardless – after depositing the toffee in his bathroom cabinet inside one of his boxes of tablets.

Empty tablet boxes that had not yet reached their expiry date made fantastic hiding places for small objects. With the prescription declaring them for the sole use of one Gordon Cooper Tracy, none of his brothers had any cause to ever touch them. Not even John knew about that hiding place. Probably. You could never be too careful with the Eye in the Sky.

"You decent, kid?" Grandma asked, knocking on the door. John flickered out of sight, and Gordon made a noise that was probably an affirmative from under the covers. She took it as such and his door hissed open. Footsteps crossed his floor, and the bed dipped near his head. He looked up to see her grinning back down at him. "As you're in bed, I assume you've done what you needed to?"

He grinned back at her.

"Yup," he admitted.

"Good, good," she said. "I must say, it's a nice change to see your brother away from that desk more. Toffee or not, he was starting to stick to it."

Gordon laughed and she ruffled his hair.

"Now get some shut eye. Your brothers will have questions if you're out and about after I sent you to bed, and with you boys' job, it's something you're all lacking anyway. If I catch you out of bed again, I'll be dragging you back in here by your ear, got it?"

"Yes, Grandma," he agreed; sleep was nice, even if he'd rather be doing a few more laps in the pool. Ah well, sometimes sacrifices needed to be made in the name of pranking.

"I'll see you later," she told him, kissing his forehead – he made a face – before leaving the room.

So, Grandma didn't want to see him out and about? Well, that was what John was for.

"Hey, John?" he called once the door was shut. His brother appeared immediately, and Gordon suspected he'd never actually left, just culled visual. "Let me know when I have another five minutes free on this floor?"

"Sure thing," his brother agreed. "What's your next plan?"

Gordon grinned at him.

"You know the story of the Princess and the Pea?"

Those of you who follow me on tumblr might be aware that I've just returned to uni to start a new degree - preparation for that was a large reason for the lack of fics, but as I'm doing a Master's degree my studies are going to be rather intensive so I can't promise any regularity with updates for any of my fics for the time being (I have some unposted backlog but I'm trying to space it so we have slow updates for a while rather than many now then none for a year!). That said, I'm still around, my PMs and tumblr are still open and I'm always up for a chat.

Thanks for reading!
