So, I was reading my best friend's fanfictions and I came across a particularly brilliant one! It's called 20 Fluffy Jagoras headcanons by Emerald Has Been Cumberbatched, who, by now, is surely famous in at least this fandom. She allowed me to do a series of oneshots on her headcanons, so here they are!

1. Jason is always the one to make sure Pythagoras is sleeping properly. If he notices Pythagoras still awake and that he hasn't slept in days he will go over to him and manhandle him into his bed and then get in with him and pull him towards him until Pythagoras is asleep.

Pythagoras truly was in his own little triangle-shaped world when he was working on his theorem. Jason didn't mind, in fact he thought that Pythagoras' driven mind and enthusiasm was one of his sexiest qualities. But it had been causing problems. He wasn't sleeping, the search for an answer devouring his life. He was beginning to grow dark bags under his eyes, and a little crease appeared in his forehead. In addition, he wasn't sleeping as much or as well as Jason would have liked.
He looked over at the blonde who was muttering under his breath and biting his lip. He looked so worried, so anxious that it tore at Jason's heart. He hated seeing his genius like this.

"Pyth?"

No answer. Pythagoras kept whispering and began biting his lip even harder.

"Pyth!"

Still no answer. Jason swung his legs out of their bed and marched over to him. He lightly tapped his shoulder, remembering to keep out of punching distance. The mathematician could get a surprisingly hard punch going when startled. Pythagoras jumped and whipped round, his features slightly relaxing when he was his lover.

"Jason."

"Come on, you. You're making yourself ill."

"No, I'm not." Pythagoras argued. "Stop fussing. I'll go to bed when I've finished this."

"Pythagoras, you'll never finish it if you don't rest."

"How can I rest? It's plaguing my mind."

"Relax." Jason pressed a kiss to his head. "Just come to bed and sleep.."

While the prospect of a comfortable bed and Jason laying with him sounded wonderful, his work was calling to him. "I will. Give me 20 minutes and I'll..."

"Pythagoras."

Pythagoras recognised that voice as Jason's tone before he started grabbing people. "For Poseidon's sake, Jason. Please let me just..."

"I know you. You'll say '20 minutes'. Then you'll still be hunched over it by this time tomorrow."

Pythagoras felt Jason's hands grip under his armpits. Stubbornly, he gripped the table, determined not to move. What he didn't take into account was the fact that Jason was stronger than he was and the next thing he knew, he was literally being lifted off his feet, the chair being ppushed away by Jason's foot, and placed away from the table. Determined to not let Jason win, he began struggling, despite the fact Jason was still holding onto him. The dark-haired man moved his arms to Pythagoras' middle and began dragging him to their quarters.

"Let me go!" Pythagoras ordered, indignantly poking at Jason's arm.

"You need rest. I'll let you get back to it tomorrow."

"No!"

Pythagoras snatched at the doorframe, much to Jason's annoyance. Why didn't the man just let him take care of him for once? He gave a hearty yank and Pythagoras lost his grip. He managed to get him to the bed and looked at him expectantly. Pythagoras stared back, defiance in his light blue eyes.

"Are you going to get in the bed?"

"Yes."

Jason looked surprised and pleased. "Great!"

"Tomorrow."

He tried to run past Jason and got as far as the abandoned chair, when he heard footsteps and found himself being picked up like a bride and getting taken back from where he'd just tried to escape. He galred at Jason with all his might when the man finally set him down.

"I'm not happy with you." Pythagoras told him, crossly.

"I just want you to rest. You're hurting yourself . And me. I worry about you."

Pythagoras felt any anger leave his body. Why did Jason have to have those unfairly sad, beautiful eyes? "Alright." He touched Jason's face, runnin his thumb over his stubble. "I'll rest, if it makes you happy."

Jason grinned and kissed him. He, too, entered the bed and wrapped his arms around his boyfriend. "I love you, Pyth."

Pythagoras smiled. He never tired of hearing that. "I love you too."

He couldn't sleep. Not for a while, his mind kept taunting him with ideas about his work. He tried to concentrate on Jason. He could feel his breathing, from where the man's chest was pressed up against his face. He could hear his heart thumping. The movement and sound lulled him and before he knew it, he was sleeping like a baby.
