Kaden is high on his emotions and thinking with tunnel vision. He might think getting rid of Everett and Atlantis will bring stability but that is not the case. Still have to worry about her second uncle and then also Elias’ purpose for looking for them (immortals). And we know Lina does not want anyone to die because of her. Lina and Kaden, please please just work together 😔
I think the worst part of their relationship is a lack of communication, followed by their expecting the worst of each other. Their lack of trust is what druves them to do very destructive things. For Kade, this manifests in him trying to hurt those that threaten his happiness with her. While for her, it translates to doing things to hurt him in spite.
