Filch Was Petrified

Unlike the three professors, the moment Filch, clutching Mrs Norris, saw the words on the wall, he let out a shriek and immediately ducked behind Dumbledore and Professor McGonagall, with only his head showing.

"Dumbledore, did you see it? The Heir—the Heir of Slytherin!" Filch stared at the words on the wall in panic, then his murky eyes inevitably slid toward Kane.

After all, in the era of the Four Founders of Hogwarts, there had been no barriers between the four houses. So there was nothing strange about the Heir of Slytherin being a Gryffindor.

"Please calm down. Right now, you are giving me the impression that, because you cannot find the real culprit who harmed Mrs Norris, you are angrily and cowardly directing your suspicions at Kane, an innocent child," Dumbledore said with a frown.

"Exactly. I don't have any grudge against you," Kane said, rolling his eyes. If anyone held a grudge, it should have been Filch hating him, since Kane had nearly gotten Filch fed to the Three-Headed Dog last year.

Although Kane had ultimately rescued Filch from danger, if it had not been for Kane, Filch would never have faced that danger in the first place. So rather than Kane hating Filch, it should have been Filch who hated him...

Wait, could Filch have kept treating him like an imaginary enemy because of that?

"I can't help it, Professor Dumbledore. From the first moment I saw him, I felt that this little wizard... he... he was no good!" Filch said with difficulty.

"Yeah, yeah, yeah. I'm no good. If I really were the Heir of Slytherin, I wouldn't have harmed Mrs Norris. The magic on that cat is more active than the magic on you. If I wanted to hurt someone, I should have hurt you."
