In "A Breath of Snow and Ashes" by Diana Gabaldon, the character's emotional turmoil and fragility are vividly illustrated through a powerful metaphor. The quote suggests that if she is damaged or hurt, her pain could manifest in harmful ways, akin to the reckless nature of a drunkard wielding a broken bottle. This imagery highlights the potential for destruction that can arise from deep-seated emotional wounds.

The metaphor captures the idea that one's inner struggles can lead to unpredictable and dangerous behavior. Just as a jagged edge can cut, the character's unresolved issues could impact those around her, serving as a warning about the dangers of unresolved trauma. This theme resonates throughout the narrative, emphasizing the complexities of human relationships and the impact of personal pain on interactions with others.
