So let's talk about Mertyl... again
So... this guy is not escaping the adoption allegations until it's proven. Good lord. Like, this is not even close to the Chion situation back then cause at least Chion looks like his parents. But Mertyl, not even close.
One thing I wanna point out though is this.
I mentioned it before that his issues with Humans makes no sense and I still stand by it.
In this panel he talked about the strife between the Humans, Fairies and Giants and how King and Diane lost some of their close best friends in the process and the panel shows Helbram and Matrona.
One, Matrona is still alive, yes that severe injury is caused by humans but it is also a human who healed her and took care of her, that is same human she ended up living with her together with his two kids who are now currently residing in the Fairy King's Forest with her. She's living her best life.
Two, Uncle Ban is human and Lancelot is half-human and it's canon and pretty obvious that King adores Lancelot.
In this panel, Mertyl threatens the fairy that is responsible for the changeling and said that King already told them to stop and told them not to wreck the relationship between the humans. If Mertyl is not so fond of humans, why would he care.
Now, here's the deal. The Nasiens-is-Kiane's-kid theory is growing strong and I think I found the reason why Mertyl acts the way he does here.
I think Mertyl knows that he's not their real kid and he's trying the best he could to be useful enough for them so he couldn't be disposed of. I don't think he has any particular strife with Humans, he just has issues with Nasiens being there because Nasiens does look like their kid and what he said about his health becoming a lot better during his stay in the fairy realm indicates that he may just be a fairy and Mertyl feels threatened by this, he wants Nasiens out of there before anything can be confirmed so Mertyl could stay there and be their kid still especially now that King and Diane already know something or suspect something about Nasiens.
