You... You were interesting. Saiki can read everyone's mind, except for Nendou, who's an idiot. But, he can't read your mind either, but he's positive you're not an idiot. You get the highest scores on tests, straight 'A' student, and are just clearly smarter than Nendou. But, to be fair, not many people aren't.

Not being able to read your mind terrifies him. It's like having a smarter Nendou, which is better, but still scary.

He's currently walking behind you in the classroom.
