"Dammit, Ron!" Harry shouted, "You have no idea what you're talking about."
"I have no idea, me?" Ron asked incredulously. "I think you're the one confused, Harry."
"Brains over brawn, Ron. That's how it works." Harry rebutted, getting in Ron's face.
"Survival depends on instinct." Ron burst. "Its survival of the fittest, Harry. Not the nerdiest!"
"You're mad!" Harry shouted.
Downstairs in the common room, Griffindor's members had gathered and were listening in on the argument in the Boy's Dormitory. With Harry's shout, paintings shook and bets changed hands, people rethinking their decisions. It was then that Hermione walked in, to see a large crowd at the bottom of the boy's staircase with shouting floating down.
Hermione walked up and tapped the nearest person on the shoulder. "Collin? What's going on?"
"Harry and Ron are having this huge fight," the younger boy breathed out excitedly. "It's been going on for almost an hour now. It's brilliant."
Hermione frowned disapprovingly as the boy turned back to the staircase. "This is ridiculous," she muttered, pushing her way through the crowd.
She slowly made her way up the winding staircase and paused before the door when she heard a crash followed by a loud thump that sounded like a falling body. She threw the door open to see Ron sprawled on the floor with Harry, breathing heavily, standing above him.
"What is going on in here?" she demanded shrilly, causing them to leap apart.
"Er…" "Well,"
Hermione crossed her arms and tapped her foot in clear annoyance. "Well? I'm waiting."
As the boys stumbled for something to say, she noticed that Ron was holding his side painfully as he stood up while Harry had an already-swelling eye.
"You see–""
Ron cut Harry off, demanding of Hermione, "If cavemen and astronauts got in a fight, who would win?"
Hermione felt her jaw slacken in disbelief. "That's what you've been fighting about?"
When they nodded, she shook her head and gestured to their injuries. "And the hitting?"
Harry looked down and shuffled his foot awkwardly on the floor. "We were trying a physical demonstration, Astronaut vs. Caveman.
Hermione broke out into a huge smile. "You two are such idiots," she laughed, as she pulled them together for a group hug.
"We're sorry, Hermione." Harry mumbled into her shoulder.
"Yeah," Ron reiterated from her other side. "Sorry."
"Promise you won't fight about something so stupid again?"
The two boys nodded to her, fingers crossed behind their backs.
Downstairs, Neville collected everyone's money, being the only one to predict that Hermione would win the argument.
