I think so too. Since all the victims of the serial killer is the same as Louis who has fair complexion, tall and black hair. Not to mention that the Duke likes him so much.
Exactly. It would be disappointing though if the child is duke's. Since the drug apparently works like some mind control it would mean the duke raped him. That is making my skin crawl. All those sex scenes would all be under the influence of the drug hence no consent.
Please, no. It better not be the Duke's child or I'll lit his dick on fire.
My theory is that the same drug was used on Louis. The reason he can't remember what happened and got pregnant. Then there is the fact that all the victims look like him and also the killing started four months ago in the story. Which is the same time Louis slept with an imperial. I am suspecting the prince or the duke who likes him.
