Ok for once I totally get Atlas anger, this isn't just "teen drama" even if they are really young, we are talking again about politics, alliances, trust, especially trust, I know it's a arranged marriage but how would feel if the person you are handling the hand of your child, that you wish they at least like each other so a nice future relationship, betrays the trust even before marriage with not less that a sibling, your other child, I would be freaking furious, people's lives and kingdoms have been ruined for less. He said what I thought before Emin could totally use this as means to ruing everything, even if he seems like a bratty teens, I'm very sure he have his own agenda to mess with this, cuz again it makes no sense, this marriage could help without the need of blood, and actually his sister would be with a flaw but kind man, I'm so sure that is a power thing, the jerk doesn't want her sister having power via marriage oooor maybe is something more complicated.
And yet I must say Atlas is stepping into dangerous territory now, he's letting aside his coolness, going head first against the storm, even if it sounds ugly, the truth is that he's still a servant, this "relationship" of "work" where they aren't in equal rights or even "trusted second hand" to be talking like that, I'm not saying his anger isn't right or anything, but you must be aware of your situation, if the prince weren't so shelter, naive and honestly no self aware privilege soft royal ufff I can't imagine what he do to Atlas for speaking like that 😬
I hope things don't escalate because the one with actual power in the balance in the prince, and angry soft ignorant people are freaking terrified when they are corner and they have the means to make your life hell.
