How we cite our quotes:
The laughter had disappeared from his face and eyes the moment his laughing voice ceased. (33)
Here's a rather shocking transition. A charming, amiable stranger turns dark and brooding as he lets his forced laughter die away. He's clearly not what he seems.
"Oh, no," she said quickly. "Nothing like that." Her eyes hardened with resistance. (43)
This small transformation in Elisa introduces a stubbornness we haven't seen before. And it marks a change in her relationship with the tinker, which, though brief, has been totally friendly so far.
"What's them plants, ma'am?"
The irritation and resistance melted from Elisa's face. (50-51)
Here's another small change Elisa undergoes as she talks to the tinker. Their relationship certainly has its ups and downs. Why do you think it's so volatile?
