If he’s about to obliterate the kid, he hasn’t the slightest reason to keep up his charade of plotting to set the Headmaster and Defense Professor against one-another.
Did he, though?
Blaise hesitated, but his curiosity was eating him alive. “Can I ask now why you want to cause trouble between Professor Quirrell and Dumbledore?” The Headmaster hadn’t had anything to do with the Gryffindor bullies that Blaise knew about, and besides helping Kimberly, the Headmaster had also offered to make Professor Binns give him excellent marks in History of Magic even if he turned in blank parchments for his homework, though he’d still have to attend class and pretend to hand them in. Actually Blaise would have betrayed all three generals for free, and never mind his cousin either, but he’d seen no need to say that.
The broad black hat cocked to one side, as if to convey a quizzical stare. “Tell me, friend Blaise, did it occur to you that traitors who betray so many times over often meet with ill ends?”
Zabini.
Obliviate.
Did he, though?
Fair enough. But nonetheless, H&C wouldn’t need a report if he’d been in the conversation Blaise was reporting on.

Unless H&C needs to figure out (through legilimancy) who else Zabini might have told about his existence, so that he can go and obliviate them too.
