She educated him alright, when he spoke out against Winter, he found his back broken again. Or at least he thought that it was, Mab proved her point as to who was in charge.
Yeah, I think it was all Mab; and essentially, an illusion.
She nailed him right in his expectations, played on his prior despair at being helpless, hopeless.
He didn't try to fight it.
It echoed the time when Harry unmasked "Shiela," and Lasciel's Shadow created the illusion of fire: Harry was out the window and about to throw himself over, not trying to fight the unexpected potency of the illusion. Later, Harry realized he was in charge of his own head, and could *always* bring the illusions under control.
I don't know if he has realized that about Mab's ability to mess with his sensations, yet (he can control those, too). Note -- she is carefully not messing with his
mind (as per his prior threat to become a "mediocre knight" if she did): she messes with the sensations, and he freely chooses to react as she wants.
Very Mab.
Harry will realize... eventually.
He'll be intensely annoyed... but at least 50% of it will be annoyance at himself.
