Good character development on Evie went from trying to get Elsa to finding love from one of the main male characters in the original story to being perfectly fine with killing a kid if it means to keep Elsa safe.
and knows said kid was meant to be one of the love interests for elsa but is willing to anyways.
No, the adult male version is the love interest and here it's just a young girl and tbf she want tostealher magic so she is right to keep an eye on her.
