Harry joins a class for enchantment and does so for a reason:
"What's your understanding of Enchanting?"
"I have none."
"Then why are you taking this course?"
"I...I'm not sure. I saw something that piqued my curiousity."
"What did you see? Maybe I can help."
"Yes, I mean, I thank you. Uhm, I mean you kinda already are."
"Pardon? I don't follow? I haven't done anything yet."
"No worries, you've done plenty."
"...oh"
"I'm sorry, it came out different than I had imagined."
"Non, don't apologize. It's...something else for a change."
"What do you mean?"
"You're the first to sign up to a course on a mere whim. Not a keen interest per se."
"Wait...what?"
"Yes, you said you didn't quite know why you're here."
"That's no-"
"And usually it's those that have a strict goal in mind who join."
"Ugh, no, I-"
"So I'm happy to show you the magic of enchantment."
Sigh "Thank you, that would be great."
