Speak louder. Also we shouldn't forget that 1. Sylhan was a player in the political game too and he was the one who "made" Gjord like this and 2. Gjord have went through the trauma of losing him for 2 years, naturally he want to make sure that doesn't happen again and is overprotective of Sylhan.
Everyone is still consistent, if anything this seems more interesting than a perfect boyfriend story.

I could care less how Gjord is acting. He’s very much I’m going to do anything for MC by any means & anyone who stands in his way will be dealt with and that’s not surprising at all. He’s been doing that since the beginning. Like I honestly could care less that he wants to sacrifice other people it’s always like that in stories like this. Like the only minor issue I have is how rude he’s been to Ishmon but even that isn’t something crazy to me cause in this chapter he’s literally just saying make sure your medicine is safe enough for MC to take. Like Idk he was right on the money, especially the part where he said your ethics have gaps in them cause you don’t want to human experiment and yet I got a dragon in my arm so what does I say about you for real? It’s either you’re all in it or you’re not. Boohoo
