Dumbledore: "Kate is a legendary genius, his magic has subverted the whole world."
Snape: "He's a super genius, and his potions are a miracle."
Malfoy: "Harry Potter, I am tempered in hell, I will let you taste the taste of thunder and purgatory!"
Voldemort: "His strength makes me unable to breathe. His students have destroyed my plans again and again."
Harry Potter: "Kate is a legendary professor. I am honored to be his student. I defeated Voldemort again and again, hehe!"
Kate is too dangerous, he is destroying the world...
