The focus in this chapter is on Adam's misunderstanding of Hetty. While they pick currants together, Hetty's thoughts are almost entirely on Arthur, but Adam takes her softened manner as indicating that she has begun to love him. Adam is so blindly in love with Hetty that he cannot really see her faults; when she puts the rose in her hair, he disapproves of her "love of finery" but almost immediately dismisses the matter. Because he believes Hetty to be a sweet young girl, he cannot recognize her extreme vanity.
Adam's situation is ironic because while he is lost in admiration of Hetty's beauty, the reader can see what a complete mismatch the two are. Once again Eliot is working with the appearance-reality motif, and she returns to it again later in the chapter when Hetty appears in the dark dress that makes her resemble Dinah. The identity switch is dramatic in that it points up how far from the truth Adam's vision of Hetty is. No one could be less like Dinah than Hetty; Mrs. Poyser knows this, and her reaction to the sudden apparition is violent. But Adam is not disturbed; because he sees Hetty in a false light, the contrast does not strike him. Eliot here, in one symbolic scene, gives us a vivid representation of how confused the normally clear-sighted Adam is.
The scene also serves to remind us of Dinah, of course. Dinah is out of the way through a good part of the novel, but the author does not allow us to forget her. Here, by referring to her in a situation in which Adam is pursuing a wrong romantic interest, and setting up a contrast between her and Hetty, she indicates where Adam's romantic interest should really tend.
