In "The Blue Sword" by Robin McKinley, the character Gonturan represents the complex nature of friendship, embodying both loyalty and independence. While she is a true friend to the protagonist, her own thoughts and beliefs can sometimes diverge from those of others, highlighting the intricate dynamics of personal relationships. This dynamic suggests that true friendship does not mean complete agreement or uniformity in thinking.

The quote underscores a caution about the influence of external thoughts and opinions in one's life. It suggests that while having supportive friends is valuable, it is also essential to navigate the challenges that come with differing perspectives. Gonturan's complexity serves as a reminder that friendships can be both enriching and, at times, potentially hazardous due to conflicting beliefs.
