((Since Amina hasn't shown up yet I decided to go ahead and start. She can jump in when/if she comes in.))
Keith eyed James distrustfully. "Sure..." He muttered, not bothering to raise his hand to the older boy. Clean, fair duels were for people who didn't really want to win, at least in his opinion. The day he did exactly what the rules aloud him to do was the day muggles put a man on the moon. For real too, not some crap special effects job done in Arizona.
Keith walked to his end of the arena and pulled out his wand. The stiff piece of wood hummed quietly against his fingers, almost itching to be used. Keith grinned.
The bell rang.
Keith immediately rolled to the left, a quick move to push James off balance. As he came up, he snapped his wand towards the older boy, a quick bark sending a burst of blue and white fire spiraling from the end of his wand. It was a standard tactic of Keith. Bluebell fire would't actually hurt James, but it would knock him off balance, at least in theory. It doesn't matter who you are, a giant blast of fire headed at your face is going to make you pause and consider your options, if only for a moment. A moment Keith could use.
As soon as the fire stopped coming, he flicked his wand again, whispering "Expelliarmus". The spell slid quietly into the flames, the distinctive blue and white hiding the brief flash of red.
