Ohh interesting i really hope this is a theory not u spilling a spoiler from a novel(not sure if this has it ) but so many ppl dont know that there is a spoiler button and u CAN use if. But i Love Theories and if this is genuine omg now this is gonna be a crazy ride and im fully on board very curious i felt he might have done that shit on purpose too .
I have never read the novel, so this isn't a spoiler, just my theory!
What..A ..great theory if it turns out like this boy is this one thick plot am here for it
