I'm seeing a lot of hate for Hild in the comments. I'm not going to bash on Hild's storyline, as I haven't dug up enough there, but the way she reacted to Thorfinn after laying out his ideology about swords is so narrow minded.
No where in his explanation does he excuse himself of what he did in the past, he is just explaining what he wants for his future. What she did is twist his words into "It's not my fault that I killed so many people, it's the sword's whisper," when that's clearly not what he was saying at all.
Her blind pursuit for vengeance is a character flaw that I can appreciate and something that I expect to be worked through and fleshed out. In the chapter before thus, we saw that she was going back to working on her designs and inventions, and she'll probably go back to what she was before her tragedy.
Yeah, her character is currently one dimensional, because she is defined by her goal, and her one goal right now is to prove that Thorfinn's words are empty and to kill him.
So I lied. I wasn't going to talk about Hild's story, but then I did. I'm probably forgetting a bunch of stuff about her.
Tl;dr
Started this comment about how I didn't like how narrow minded her reaction to Thorfinn was, but then started talking about how this narrow mindedness is a character flaw that needs to be addressed, so all y'all need to chill on the bitch.
