A/N: For the There's a First Time for Everything Challenge (George Weasley, first lost tooth)
"Trust me," Fred says.
George hesitates. It's the first time he's ever really doubted one of his twin's plans. Of course, it's also the first time Fred has ever come up with something that sounds so painful. "I dunno, Fred," he says nervously, shuffling his feet. "I don't think it's a good idea."
"Trust me," Fred says again. "I won't do it if you don't."
With a sigh, George nods, closing his eyes. "All right," he mutters. "Make it quick."
"On the count of three. One..."
George tenses, trying to brace himself.
"Two..."
George pokes his tongue against his tooth, feeling it wiggle for what will be the last time. Maybe it won't be so bad.
"Three!"
Even with the warning, the pain of his brother's fist crashing into his mouth is too much of a shock. George screams, his eyes opening again.
Fred looks hysterical, his knuckles covered in a thin layer of blood. George's blood.
George touches a hand to his lip. Sure enough, his fingers brush over something warm and slick. But in spite of his panic, he laughs as he opens his mouth, spitting out the once loose tooth. "It worked!"
Fred seems to calm down at once, his stressed features relaxing, his lips twisting into a triumphant grin. "I told you it would!" he laughs.
"Boys, what on earth is going on in- Georgie, what happened?" their mother demands, rushing to the bleeding boy and cradling him in her arms. "You're hurt!"
"Fred punched my tooth out!" George explains gleefully, pulling back and offering his mother a wide smile so that she can see the new gap in his mouth.
Their mother is not as amused as they are. She fixes Fred with a stern glare, releasing George so that she can rest her hands on her hips as she often does whenever one of the boys is in trouble. "Why in Merlin's name would you do something like that?" she demands.
Fred smiles, unabashed. "So you can tell us apart," he answers, as though it's the most obvious thing in the world.
