Theory: Ŗeżżőcħ manipulated Thrull

So, in book 9, we saw that Thrull used to be an enemy to Ŗeżżőcħ, just like Jack and his friends, but somehow, he turned into one of his servants.

My theory is that, just like he tried to do with Jack, Ŗeżżőcħ manipulated Thrull using the Winged Wretch King (sorry if I wrote the name wrong), showing him a future where he disobeyed him and all his friends were killed off. Heck, maybe he even said that he was Thrull's fan, just like he said the same thing to Jack.

Anyway, this is just a simple theory, a mere possibilty of how Thrull joined Ŗeżżőcħ's side, and also one that would increase the amount of paralels between him and Jack.
