She knew the child going to be poisoned but sait nothing about it
The original "book" the child was claimed to be sick, not poisoned. The cheating queen was the heroine of the novel, so if she was poisoning the prince, that wouldn't be very heroinely. Think of it like a novel written with an unreliable narrator. So the FL doesn't know that the prince is being poisoned, she just suspects it because of the timing.









I wonder if I'm reading the same thing as I don't understand the hype about Jainer. He knew Deyeve was bullied but didn't lift a finger. WHY ? too tired to repeat the same things ? His baby brother is still an innocent child. He wasn't too tired to rebuilt his assassin guild though. He is worst than the father.
