Nya's anger fascinates me. Kai is labeled the hothead of the group from the get-go but after gaining some confidence and closure he really mellows out and becomes much chiller. But Nya's anger never gets to burn out. She doesn't get closure on the things she's angry about, she's forced to push the feeling down to focus on whatever task she needs to complete and then it sits in her stomach and simmers until it boils over again. When her brother got character development and growth, she got fridged and traumatized. After being resurrected for the second time, how do you think she feels, seeing Kai smiling and careless? After all, he's the one who showed her how to feel about unfair situations. He's the one who taught her anger in the first place. So how come he got to snuff it out like it was nothing, while she still has to fight the raging storm inside her? It just isn't fair.
