The fortune teller referred to Suu as the missing piece. And Sahara keeps trying to eat him. So my guess is that Suu has some variation of the regeneration power. That would explain why Sahara only turns into an adult around Suu.
So the crown prince would need to use Suu to evolve and control Sahara, but that's too dangerous. As Sahara said before, he hates the crown prince. I wonder if he'll be able to kill the dragon.

My guess is that he killed that person Clark saw on the news. And is going to give him the missing wedding ring. Hopefully not with the victim's finger attached LOL
Here is why I think so:
The psychologist told him that in order to become best friends with the cat (that looks like Clark LOL), he needs to "feed" it. What does Clark likes? Crime! He collects info on crimes that no one else knows. So Alex decided to kill more people and give evidence of the crimes to Clark.
Things are getting dark really fast. I feel sorry for the innocent people about to get killed just because a crazy guy didn't get enough attention from his crush.

The dragon's name is "Desert"*, he is highly poisonous, eats humans and has already said that their kingdom will get no rain whatsoever.
Wasn't the point of raising Saharah solidifying the Prince's position as the heir to the throne by bringing rain? The Prince shoud just get rid of the dragon. And add Suu to his harem LOL

Ok, so Suu and Nadan did have a romantic relationship at some point. Or a purely physical one. But judging by how Nadan acts now he is either in a relationship with someone else or the fact that Suu is a freeman while he is still a slave bothers him.
And I don't get him. Think about it! If you were a slave and your ex was working his ass of to buy your freedom wouldn't the logical action be to at least be nice to him? Even if you don't care about him at all, that's an opportunity too good to pass! Especially considering that the most you need to do is give him a feel smiles! Is that too much to ask?! WTF Nadan.
Something is off about that guy.
THE DOCTOR IS NOT DEAD! Alex killed a random person:
