"Holy shit! Wait, that's not right!"
Tris had been lying in bed, about to start meditating, when he suddenly sprang upright. He startled Ron, who was reading a book for fun beside him.
"What are you doing?"
"Nothing, nothing. Keep reading." Tris waved for Ron to ignore him, but his mind was racing.
He had just gone over his abduction that day and suddenly noticed something wrong.
When he had caught his opponent through the shadow mirror world, his first instinct had been to use Legilimency to obtain the knowledge in the man's head. Yet after those Dark Wizards captured him, they hadn't used the same method to find out where the Philosopher's Stone was.
It certainly wasn't because they were law-abiding citizens.
The fellow who had later used undead bone magic had sworn he would use the Cruciatus Curse on him. Tris was certain he hadn't been making an empty threat.
So why hadn't they used Legilimency or the Imperius Curse?
The most likely reason was that they knew those spells wouldn't work on him.
But why? How had they known? They couldn't have tried before. He would have known immediately if anyone attempted to use mental magic on him.
So had they learned it from someone else? Who could it have been?
The professors at Hogwarts?
It was possible.
The Sorting Hat knew that his mind couldn't be probed from the outside and might have told Dumbledore. It would make sense for Dumbledore to tell the professors, too.
But would the Hogwarts professors betray him?
Tris didn't think so.
Well, Lockhart might be an exception, but would Dumbledore and the others tell Lockhart about this? Probably not.
Besides, if that was all these wizards knew, they might still have given it a try.
Unless they knew for certain
