Eilonwy blinks in surprise as the fourth bride is mentioned, and while she's still feeling sad for the three that died this twist is helping to make the entire experience of the story easier to roll with. It's a mix of emotions but not one that she dislikes.

Stories can and do come in different versions. Even if most of the legends back home end in some sort of 'And the hero was remembered for their bravery' final line, or 'With hard work you can achieve anything' note on morality. There were other stories but Eilonwy had been barred from hearing the terrifying ones, which helped feed her ideas of how fairies and the supernatural work. That might be a problem in the future, but she's not focused on that right now. Right now, the supernatural is friendly and normal.

As Li Lianhua continues, she leans forward slightly. The fourth bride found a mirror and a love letter? Eilonwy goes from rubbing her arms to folding them in thought. "Was the letter from a former lover who moved away, maybe? Letters are used to keep in touch, so.. Maybe that was held onto as a memento. Could the mirror be used on the lake itself? Or could the fourth bride look into it and see the other three?" Her mind is whirling with ideas on how this can resolve, and she's fully invested in hearing more.
