Went ahead a lil bit in the raws and from my understanding.. it's the hate coming from his mother's death. The trigger was the necklace that was given to him by Joffrey.
My guess is that the queen learn about the necklace and got the mom killed cuz one of the condition both woman made is that the mom can't meet Edward. Thus, seeing the necklace made the queen think they met somewhere.
And tbh.. Edward hate the queen more than Joffrey.. like- Bich even tried to win him over in this Academia arc lol

Why does Edward hate joffrey??
