I'm surprised Quirrell couldn't do a better job with the note. He could have given Harry the memory of making a new self-recognition policy, which would be a sensible thing for Harry to do after his occlumency training.

1) It's not clear how easy it is to Memory-charm an Occlumens. 2) As far as we know, Quirrel & Harry can't directly use magic on each other.

Your point 2 is another thing I'm getting pretty suspicious of. Quirrell has set up a very long plan, and could easily have faked this effect with wandless magic, or an enchantment he could later dispel, all along.

I find it highly unlikely that he faked the Avada Kedavra/Patronus effect in Azkaban...

That could just be a feature of the True Patronus, which is pretty anti-death and especially anti-indifference-to-other-people's-lives.

But that's the first time Potter sees their magic interact, so what effect did Quirrell fake?

The sense of doom. I thought the magic-can't-interact was mostly just the strongest edge of that--e.g. (maybe "i.e." too) their magic could interact but it would hurt them enough that they don't try.

Memory Charms on students set off the wards, so he'd be drawing attention to himself (plus he'd need to have Sprout do it, which may have various complications of its own).

Why is this comment retracted?

Apparently Professors can cast memory charms without setting off the wards.
