"When is your birthday?" Wilbur was smiling at him. He was doing that thing where he leaned into Technoblade's personal space and asked him questions. Apparently, it was a vital part of the human bonding process because Phil would always laugh and tell him to take it easy. That despite Wilbur being excited about finally having a little brother, he should probably give Techno time to adjust to his presence first.
Wilbur wasn't fond of listening to that advice.
"What's a birthday?"
Going by Wilbur's reaction, you'd think Techno had asked him something incredibly dumb. His eyes became impossibly wider, lips pursed into a contemplative frown. Techno didn't like it, but had become used to it. He had lived in this house – Phil's house, he reminded himself – for three weeks since the man had brought him there. And Wilbur always looked at him like that when Techno said something he considered strange.
"The day you were born," Wilbur explained.
Techno shrugged. "Oh... I don't know."
The Nether didn't have days and nights in the same way the Overworld did. That was one of the many things Technoblade had to get accustomed to now. Where he came from you either were tired and needed to sleep, or you were awake and needed to fight for survival. But he had come to know the sun and the way it would move across the sky. Rising high to shed light on the world or disappearing and suddenly casting the land in darkness.
Phil explained to him that when the sun is visible you stay awake and when it's not you're supposed to sleep. Techno still just slept when he was tired.
"What do you mean you don't know?" Wilbur near gasped. Techno glanced at Phil's back desperately, hoping for some kind of escape from the conversation. But Phil was making breakfast and Wilbur was asking him questions.
He looked away. "I don't know what day I was born," he repeated, not grasping why it should matter.
Wilbur hummed lowly, finally accepting that Techno really didn't know. Technoblade thought that'd be where it ended but when Phil turned around to put the pancakes he had made on the table Wilbur turned to his dad with a concerned pout. "Techno doesn't have a birthday," he said solemnly.
Techno picked at the table cloth, growing increasingly self-conscious. He barely knew what a birthday was but with the way Wilbur was talking about it, he felt as if he was lacking something very important.
"In that case, I guess he'll have to pick one," Phil answered easily, using a fork to deposit a pancake on each of their plates. "Any day will do really, so long as we can celebrate." Techno was still getting used to Overworld food, but he liked pancakes. They tasted a lot sweeter than anything he'd had before.
"He can have mine!" Wilbur shouted suddenly, struck by divine inspiration. "I mean, we can share. We can share my birthday." He smiled brightly at Techno.
"I guess," Techno answered lamely between bites. He still didn't get what the big deal was.
"Then we can be twins," Wilbur decided.
Phil chuckled softly. "That's not really how that works, Wil."
"Is too!" As if it would add weight to his argument, Wilbur pounded himself on the chest with one hand. "Twins are brothers who share the same birthday. So if me and Techno share my birthday we'll be twins."
Techno chewed thoughtfully. Phil was very smart, but what Wilbur was saying made sense to him too. "We can be twins," he agreed softly after a short moment, making Wilbur beam brighter still.
"Twins with a two-year age gap," Phil added.
Neither of the children was listening to him, set on their decision.
And even years later - when they both knew better - they could still agree. Despite not being born on the same day or even from the same parents, Technoblade and Wilbur were twins.
I have a prompt list for this but requests are open, if you have any!
