Three Times Alan and Tron Flaunted Their Twincest (and Two Times They Didn't)

ONE

"So, what do you think, Tron?" Kevin Flynn stood with a proud grin, hands on his hips, surveying the landscape.

Yeah, he finally brought Tron into the new Grid.

Truthfully there wasn't that much to see yet. Just a few buildings, that were the beginnings of a city, and several diagnostic programs going about their business.

"Why is it so dark?"

"Huh?" That wasn't quite what Kevin had expected.

"It's dark." Tron glanced at Flynn with a half-accusing eye and reached for a short stick attached to his thigh. It wasn't quite as long as the lightcycle baton and for a moment Kevin was puzzled as to its use. Then Tron clicked the thing on and Kevin realised with surprise that it was a flashlight.

"Oh come on, man," he moaned. "It's not that dark."

Tron didn't look convinced. He swept the flashlight beam over their surroundings and then shone it into Flynn's face.

"If you say so."

Kevin shielded his eyes. "Come on, turn that off."

Tron clipped the flashlight back to his thigh, while Kevin blinked away the afterimages. The expression on the program's face spoke volumes. And most of it was along the lines of 'Sure, whatever, Flynn'.

In fact it was the exact same expression Alan gave Kevin just yesterday when Flynn was trying to explain why he was late for their business meeting again.

Huh, that had the potential of becoming just a little bit creepy.

"Okay, man." Kevin raised his hands in a placating gesture. Then he crouched and put his fingers to the dark, polished surface of the Grid. "How about now?"

The luminance levels went up a fraction as the lines of the Grid glowed just a little brighter.

Tron's mouth quirked in a smile. "Much better, thank you."

"Yeah, just don't say I never do anything for you." Kevin stood up and grinned at the program.

Tron frowned. "Why would I say that?" he asked, honestly confused.

"Ah, never mind." Flynn took his lighcycle baton. "Ready to visit the City?"

"Of course, Flynn."

Several hours later, in the real world...

Alan stood at the front door of Flynn's Arcade, watching the crowd of teenagers leave the place. It was closing time, but fortunately the no-nonsense-looking girl in charge of the Arcade for tonight recognised him before Alan had to whip out his Encom badge to prove he worked with Flynn and actually had a valid reason to be here at this hour.

Alan doubted he'd have much success anyway, even if he did wave his Encom credentials, along with a ten-dollar-note in her face.

"Hello, Mr Bradley. If you're looking for Mr Flynn, he's not in. I'm sorry, but I don't really know when he'll be back and I need to close for tonight so maybe you could come back tomorrow?"

"That's all right. I can wait for him and close the Arcade myself." Alan tried to project his trustworthiness because, damn, he didn't come here all the way just to have the door closed in his face.

"Really?"

Alan nodded. The girl looked at him sceptically, but apparently came to the conclusion he could be trusted with the keys.

"Uh, thank you." She flipped back her long hair and handed Alan the keys. "You'll tell Mr Flynn it was your idea, though? I don't want him to think I'm slacking off." The girl threw the strap of her bag over her shoulder.

"Sure." Alan nodded again. He liked her responsibility. It gave him certain hope for the younger generation - a hope that was severely tested each time he saw all those kids hanging around the Arcade and spending hours playing video games.

"Okay. Bye then."

She stepped out onto the pavement, and Alan went inside the Arcade, locking the door behind him.

He looked around. The Arcade was actually a pretty big place when it wasn't crowded and when he didn't have to squeeze through the mass of people to get anywhere further than ten feet from the door.

Flynn's room above the Arcade floor was dark, but Alan called anyway. "Kevin, are you there?"

Nobody responded so Alan resigned himself to waiting. He wandered slowly in the general direction of the upstairs flat, thinking of the undeniable comforts of Flynn's couch - if he had to wait, he might as well get comfortable - when he spotted one of the machines.

It was the TRON game. Alan was vaguely aware that Kevin gave one of his games the name of Alan's security program, but he could never quite understand what a firewall had to do with throwing frisbees.

He stopped and looked around. He knew there was no one here, but he still felt the silly need to make sure. Silly because it wasn't as if he was about to do something illegal or even particularly embarrassing. He just wanted to see...

Alan took a quarter out of his pocket and pushed it into the slot of the machine. He could hear the coin clattering inside, suspiciously long, and after a moment it dropped out of the machine and rolled onto the floor, stopping by his shoe.

Alan frowned. It wasn't like Flynn to leave one of his games in such a state of disrepair. He bent down to pick up the coin and at that moment he noticed the marks beside where it lay: worn grooves that could only be made by something being dragged repeatedly back and forth over the floor. The most probable something being the TRON game itself.

Alan glanced around again. Still nobody there.

Well, what could it hurt?

He pulled and the machine swung outwards, revealing a door.

"Kevin Flynn, what on Earth are you doing there?" Alan murmured to himself and went in.

There was a flight of stairs leading to the basement level of the building, but there was also a light bulb hanging from the ceiling, so Alan at least didn't have to worry about falling down in the dark and breaking his neck. That was always a plus.

"Flynn, you there?"

Alan still didn't hear anything, but as he reached the bottom of the stairs there was - surprise, surprise - another door. Well, he got this far, it would be a total waste of his time to stop now.

Alan turned the handle. "Flynn?"

Kevin turned towards the sound of the door of his little 'office' opening.

"Alan?" Kevin blinked.

"Finally." Alan stepped inside the room. "Why are you-" He stopped abruptly as his eyes found the huge machinery stationed behind the chair Flynn was currently occupying.

"Is this Lora's laser?"

To say that Alan didn't expect that would be a major understatement.

"Uh yeah, but listen, man..." Kevin trailed off as he was fixed with Alan's calculating look.

"Would you care to tell me what exactly you are doing with that laser?" Alan came closer to where Kevin was sitting. "And-" he stopped again as he looked over Kevin's shoulder, "-with Dillinger's desk?" he finished in disbelief.

Kevin ran a hand through his hair.

"It's not Dillinger's desk."

There was a sceptical 'Mhm' to his side and Flynn rolled his eyes.

"I took the spare laser from the other bay for my project."

He stood up and went to close the door. "What are you doing here, anyway? Did anybody upstairs see you come here?"

"No." Alan was still staring at the desk's surface, reading the output it displayed. He dropped the keys onto Kevin's hand when the man came to stand next to him again. "I closed the Arcade."

"Oh. Thanks." Kevin took the keys, puzzlement written all over his face, and looked at them for a moment as if he didn't know what to do with them. Finally he put the keys in his pocket and then he reached to turn off the display on the desk, breaking Alan's mesmerised state.

"Now, what can I do for you?" Kevin propped himself up against the back of his chair. "It must be something important, right? Did something happen?"

Alan grimaced slightly, realising that what he had to say was - looking at it now - spectacularly unimportant.

"No." He took off his glasses and rubbed one eye. "I brought you the updated copy of Tron."

Alan put on his glasses again and glanced at his friend, only to be met with Flynn's uncomprehending stare. He frowned.

"You asked me today about moving it to the new system, but then you disappeared somewhere and I didn't have the chance to give you the upgraded copy." Alan took the floppy disk from the inside pocket of his jacket and placed it on the desk.

"Is this the new system?"

"Uh, yeah."

Nothing else seemed to be forthcoming. Flynn still stared at him, looking as if he was on the verge of zoning out or plotting something. Alan found he did not care much for either and cast a slightly unsure glance around the basement.

"Why is it so dark?"

"Huh?" Kevin blinked.

"It's dark," Alan repeated and reached into his pocket, producing a... flashlight.

Kevin gaped.

"I-it's not that dark," he stuttered just a little, the words falling from his lips almost automatically.

He managed to see that Alan threw him an entirely unconvinced look before the man shone the flashlight straight into Kevin's eyes.

"If you say so."

For a second Kevin only stood there, immobile, with a stunned expression on his face. Then he let out a breathy laugh. "Come on, turn that off."

When Alan did, Kevin was blinking the afterimages and still grinning like a loon. Alan had exactly one second to wonder if he should perhaps start getting nervous now, before Flynn was all over him, arm around his shoulders, clapping Alan's back enthusiastically.

"Alan, man, I just had a great idea. Let me tell you a story about a whole new world."
