It seemed that a snowball fight was something that both Weasley brothers needed. Fred had only just gotten here; he'd been separated from the world that he had known, torn into this mess of a bleeding apocalypse instead. Ron, on his part, had been here nearly two years on his own. He'd had a few friends pop in and out, sure, but it was the idea of his own actual family being there with him, blood and all, that made the world a bit brighter than it had once been before. Fred might well have been the biggest prat that Ronald Weasley knew, but he was a prat that Ron cared about and trusted with his life. Not that he'd openly admit that out loud or anything, but there it was.
"What's this, Fred? You can't fight your battles without your wand?" Ron grinned, even in spite of the snowball that nailed in him in the shoulder. He rolled out of the way and back behind his tree, already dropping down onto the ground to scoop together a few more balls of snow. "I suppose I could expect as much from you," Ron continued, hurriedly building his own steady pile before himself, "you're not wizard enough to take me on without magic."
It was a challenge. One that Ron fully expected for Fred to fail on. Even if Fred could defeat him without magic, he still had the disadvantage of being far from innocent in the heat of battle. He'd resort to magic. Cheat, somehow. It was in his nature to pull up a nasty trick at the most unexpected of moments, which was why Ron planned on going into this battle with his guard held up high and a few tricks of his own up his sleeve. If living with the twins had taught Ron anything throughout his childhood, it was that he had to play with their rules in mind. If he didn't, they'd one up him. It was how they worked and they did it very, very well.
Peering out cautiously from behind his tree, Ron scanned the area for Fred's familiar mop of red hair. Once spotted, Ron hurled a snowball in Fred's direction and threw himself back behind the tree for cover.
