Hogwarts: What bad intentions could a little Hufflepuff have?

"My magic will fulfill my wish the same way, compressing it..."

"This is what I've figured out recently—the essence of magic..."

"If you still don't understand... there's an even simpler way to put it."

"Which is... all you have to do is make your wish properly, then leave everything else to wonderful magic..."

Snape and Agatha both sank into thought.

Black's words gave their understanding of magic a violent shock.

If magic really was as Black believed...

Then did that not mean there was no need for spells at all?

Whatever magic you wanted to use, you could simply think about it and it would come out?

"No... no..." The first to object was Snape.

He said in a low voice, "If it's as you say... then what meaning do incantations and casting gestures still have?"

"You should know how important incantations and casting gestures are..."

Black asked with a smile, "Oh... Severus, you've seen Voldemort and Professor Dumbledore cast spells. Do they make any unnecessary movements?"

Snape was momentarily at a loss for words...

He really had seen Voldemort and Dumbledore act with his own eyes!

Voldemort's Killing Curse had never followed any kind of casting gesture.

He had always simply raised his wand and fired...

Even loudly reciting the incantation for the Killing Curse was only to intimidate others.

Snape would not be naive enough to think that Voldemort could not use the Killing Curse without saying the incantation...

As for Dumbledore...

In Snape's memory, Dumbledore rarely even used a wand when casting spells...

Besides, if incantations and casting gestures were necessary...

Then wouldn't wandless casting and silent spells be impossible?

With no wand at all, what gestures were there to speak of?

Without reciting an incantation, what spell was there to speak of?
