Mysti supplied a name for the first year and Sasha nodded his head, ignoring Josh's comments about pro-players coming back from injuries. Considering the context clues, Sasha suspected that wasn't what Casey wanted to hear. But, the pot-wearing elf scurried off to fetch the crate of balls and Sasha pointed his broom upward and gained altitude.
Casey elected to practice chaser. Mysti herself was a chaser and Josh played beater. Before this year, Sasha played chaser for Ravenclaw so he was familiar with the position. "So, why don't you and Mysti be Chasers - you can work on passing back and forth to each other and trying to score." Sasha gestured down towards the quaffle in the crate, hoping the elf would understand his unspoken request to have the ball passed to his person. Or, master. Or whatever elves called their people. "I'll play keeper and Josh can be beater with just one bludger."
"Why don't you and Mysti practice passing the quaffle to one another. Just basic passes."
