"We are going to Queen Melanie's house!" said Paul to the coachman when he realized he could talk.
When he could talk, at that very moment the horse-drawn carriage was already really far from Voxprime. Paul must have been furious with Melanie's actions. So he couldn't say what he wanted to tell Ivy and all.
How could he not be angry if he wasn't told that Ivy had given birth? He even only knew from the invitation about the thanksgiving party that would be held for the birth of the son of Princess Ivy and Prince Theodoric.
Whereas in the past the agreement was that Ivy gave birth in his palace accompanied by him. But in reality, everything is the other way around.
His trust in Melanie was dashed. The woman he considered his mother made him hate her. In fact, Melanie herself said that she already considered him as a child.
While he was lamenting his annoyance, the carriage suddenly stopped. Make it bounce forward.
