They haven't told her how long it's been. It feels like it's been days. So - probably it's been fewer days. They'll still probably raise her. They'll still probably raise her.
She's not ahead of schedule on her scribing. Being good at math isn't the same as being fast at writing. She would obviously go feed the potion-tops to the petrified angels if she had time, to show what a good soul she is.
But Asmodia doesn't have time, so right now she's feeding the potion-top to a less useful apprentice, one very close to her own desk, but not the closest one in case that was some sort of trap for lazy girls. She has no idea who this boy was in life, he looks young but could easily have been here for a hundred years for all she knows, his tongue is burned away and reburned by the line of potions he regularly drinks. What happens to him if he doesn't drink the potions, Asmodia doesn't know. He's chained to his desk and can't stop her, doesn't try to stop her, each time she pours one of the potion-tops into his mouth. Maybe he thinks Asmodia is authorized to do whatever she wants to him, maybe he doesn't realize he could fight back, maybe he isn't in fact allowed to fight back at anything done to him, Asmodia doesn't know.
Asmodia wouldn't waste any time on pitying him even if there was any pity left in her nature. There's very little doubt that copying spell diagrams for distribution in Cheliax is one of the best jobs in Hell, optimized mostly around maximum production for Cheliax and hence unable to distract the petitioners too much from relatively delicate work. Asmodia's going to be retrained into a contract devil when she dies and that will be much much worse. If she could get this boy's position for herself, when she dies, by throwing him into a lake of fire to burn there forever, there's no doubt she'd do that too. Maybe that's how the boy got his position, by being extra good and doing horrible things to somebody like her.
She hates him. He's so much better off than she'll be. The passive way he accepts her punishments feels like he's mocking her, like he's suppressing a smile knowing how much worse she'll get hers, in time.
Asmodia asks her contract devil if she's allowed to hurt that boy more for any kind of extra credit, if she has only a little extra time in her schedule but not enough to go feed petrified angels. She doesn't want to waste potions by feeding him extra potion-tops.
They'll still probably raise her. They'll still probably raise her.
