I hope son of the noble didn't become dickhead no.2 after his father beCome a better man
"I can use this!

Nah, too obvious, and spanning 2 entire chapters. It will turn out to be a ruse where its subverted and he is actually a super good guy. And he was described as intelligent before, so he will have some super good welfare plan!
...I wish. Not like author proved to be competent enough for that, he even ended a prior chapter on a "cliffhanger", only to then retcon it and say a random dragon did it.
