Prompt 1. Finger.

AN: This is my first ever IANF fanfiction! This is one of those that is more Sam x Six then it is general friendship. It's one of the shorter ones, so I'm working on the length. Hope you like it anyway.

"No, Sam that doesn't look right."
"Come on, are we really getting into a genetics argument right now?" Sam, Six and Four had been driving for three days straight, putting as much distance between the town they'd been in for the past few days and where they were now. Somehow, they had gotten onto the topic of genetics of finger and thumb straightness.
"Yes. Yes we are."
"Fine then. Technically, the gene for straight thumbs is dominant over the "hitchhikers" thumb, and so it's your thumb that doesn't look right."
"It may be the dominant gene, Sam, but it doesn't mean it's what most people have. If both your parents have the hitchhikers thumb, you'll get it. Apparently, more people have the hitchhikers thumb then they do straight thumb, and so, by logic, your thumb is weird. "
From behind the wheel of the car, Four sighed.
"I liked it better when you were both asleep."
"Shut up, Four." Sam and Six spoke at the same time. Four rolled his eyes, and turned back to the road. Sam turned back to Six, his next point in his argument forming in his mind. Six, however, had different ideas, and ambushed Sam as he started speaking.
"But - " Six didn't give him a chance to start arguing before poking a finger to his side. "Hey! That wasn't fair." Six winked.
"Shut up. Why are we arguing about genetics, anyways?" Six rested her head on Sam's shoulder. Sam automatically rested his cheek on her head, and placed an arm over her shoulders.
"You tell me, Six. You started it." Six smiled, and picked up her head, kissing Sam gently on the cheek.
"You keep thinking that, Sam." Sam smiled, and Six closed her eyes, snuggling closer to Sam's warmth. Soon, she was asleep.
"Happy now, Four?" Sam said, watching John.
"Not really. I wanted to know who'd win the argument."
"Shut up."
