Paul burning the manuscript in front of Annie while taunting her about how good it is. Of course, he was bluffing, but after spending the entire book at her mercy, the poor guy deserved to defeat the goddess.
Paul::*tauntingly shows her the burnt pages* "You want this? Then EAT IT! *shoves the paper down her throat* Eat it till you choke you sick, twisted fuck!"
To say nothing of the ensuing struggle, after getting beat on the head with a typewriter twice over, her arm set alight, her nose broken and eyes almost gouged out and choked with the charred remains of her dream novel, it's safe to say Annie got a good idea of the horror she'd put Paul through.
