I do believe her story is about discovering who Thor is. But it is a self discovery for Jane and an exploration for the reader. Aaron is asking questions about Thor, Jane is answering some of them for us through her actions. The point of the story is to get to the heart of what it means to be Thor partly by removing elements that allow us to take those ideas for granted. This is why complaining about Thor being a name not a title totally misses the point, Aaron is removing that simple answer. Being Thor is not just about being born Odin’s son or being the Prince of Asgard.
If the lesson was primarily aimed at Thor then why have him kidnapped and moved entirely out of range of the message for most of her story?
