The meeting ended quite abruptly when what looked like a herd of masked men burst through the door. "W-What?" Slughorn gasped. Why did it have to be something he was completely scared of? Men in masks usually meant they were hiding some evil intent, and he hated anything having to do with evil.

He shuddered. Terrifying.

When spells and jinxes started flying through the air, though, he knew that this was a serious matter. He couldn't very well run away. He'd try and defend his friends and himself as best as he possibly could.

"Expelliarmus!" One person pointed a wand at him. "Praemo!" Being as he was not the fastest person in the world, he quickly pulled out his wand and shouted, "Protego!" A simple, shielding charm that effectively blocked what was thrown at him.

"That is something you'll regret. Instabilis!" Pointing the wand directly at his legs, he hoped to catch him off guard and effectively perform the Jelly-Jegs Jinx.
