SPOILER!!: Helping out!
“Oh, thanks mate, that’s right decent of you” Sabbath said as he looked up at the tall boy who’d offered to help. “It seems I haven’t grown quite enough yet… First year problems, hey” he smirked feebly at his lame joke. He pointed upward “You see, I’ve managed to stop it, but now I can’t reach it to put in the basket. Would you mind?” Sabbath thought the tall boy seemed nice enough, albeit a little shy.
Sabbath waved his wand stopping another ball, closer to the floor this time “Arresto momentum” - snitch -plonk. Another for Ravenclaw.
Sabbath turned to the tall boy, “Hey, you really look like you know what you’re doing there with that banishing spell. How does the incantation go, and how to you move your wand??? he enquired boldly wondering if the boy would be daring enough to offer a quick tute.
Rory looked down at the first year and back up at the motionless ball hovering in midair. If he remembered correctly, even as a first year he was unnaturally tall... he was always tall...Ughhh... not as fun as it seems.
"Yeah no problem," he mumbled not laying his eyes off the blue foam ball. He would gladly help.
The Ravenclaw stretched his arm towards the ball and with a small hop he caught it with ease.
"Here you go," he said looking down at the boy, with a weak shy smile, passing the ball to him. "
Why are you SO nervous!" he thought to himself, keeping an indifferent expression. He needed to feel more comfortable socialising with others, lately this small issue was getting on his nerves. He still enjoyed being alone, probably still preferred it... but STILL!
The boy, continued talking. Rory stared down at him. He felt pleased from the compliment, causing him to release another smile, this time bigger.
"Th-Thanks," he replied feebly - still smiling. On the other hand, this boy was asking him for... as if an... explanation about this spell.
"But Professor Baxter clearly said only fourth and fifth years to practice Depulso," -but-
"Rory come on! You as a first year always wanted to know what the big kids were doing. This guy is just like you! A typical Ravenclaw!" Ughhh... dilemma. The fourth year despised dilemmas.
"Well," Rory began,
"the incantation is Depulso." The professor wouldn't mind him explaining the spell to a younger student, it couldn't harm anyone, not even a fly.
"And the wand movement is a simple sweep." He demonstrated the wand movement precisely as the professor did.
"So together," he continued targeting his wand at a blue foam ball, he preformed the sweeping wand movement and said,
"Depulso." The ball was banished straight into the bin.
Yep this charm, undoubtedly, was awesome.
