My Valonqar Theory That I Just Wont Shut Up About:
It's Young Griff/Aegon VI/Faegon. Let me explain.
Maggy the Frog doesnt say "your Valonqar" just "THE Valonqar", implying that it doesnt have to be HER "little brother" (i.e. Tyrion or Jaime).
Also why does Maggy specifically use the High Valyrian word for "little brother"? She could have just said it in Westerosi if it wasnt important. Yknow who else is a (supposed) little brother who presumably has been taught High Valyrian? Young Griff.
I suspect that the Hands that choke Cersei out might not be literal hands, but Hands of the King (perhaps YG will name both Joncon and Varys as co-hands? Or Joncon's greyscaled hands will infect her, and it will eventually spread to her throat, asphyxiating her).
