The members of the Flying Squad assembled on the pitch for a so called Quidditch practice lesson. Ginny had a bunch of colored balls in two net bags, all moving about.
“Okay, pay attention.” She started. “These small colored balls, about the size of an apple, are your targets. They are charmed similar to Golden Snitches. Your job is to catch them. They will try to avoid you. Once you catch one, release it and go after another one of a different color.” With that statement, she released the hold on the bag and they all flew off.
“Now, here’s your problem. These colored balls, similar in size and mission to Bludgers, are charmed to distract and hit you. You have to fire at them to avoid getting hit while you try to grab a snitch. You can use any hex or curse as long as you hit them. Think of them as Death Eaters. This will strengthen your flying skills of shooting your wand at a moving opponent while you’re flying. Got it? I will release them as soon as you’re in the air.”
“You will be scored on how many Golden Snitches you catch and how many Bludgers you hit. Ok, up you go!”
There are many things Ginny can do to help the war effort. Teaching shooters on brooms is one way. What’s yours?
