Based on the last sentence that the heroine uttered, I think it's just about giving the prince emotions(which he already has but Tia is too oblivious to realize that) so that he will be happy in the end and not be emotionless, waiting for death. But the thing about gunpowder confused me so maybe there's still something left unsaid?
I really just want to know what Bertia is trying to avoid in the long run. She's so adamant about avoiding this "bad end" and I just want to know how bad it is. As much as I dislike her for her assumptions if the "bad end" puts the people she cares about at risk imma be big sad.
