The supporting characters in The Bell Jar are not there just to fill out the cast. Doreen and Betsy, two fellow interns in New York, offer Esther very different models of how to be a young woman, and Joan Gilling, whom Esther meets later, becomes a strange kind of mirror. Students who write about these characters have plenty to work with.

A foil is a character who contrasts with another in order to highlight particular qualities. Doreen's wit and rebelliousness contrast with Betsy's wholesome conformity, and both throw Esther's own uncertainty into relief. Character foil essays are a good way to practice analysis, since they ask students to compare and to interpret.

The most common problem in these essays is that they become character sketches. The student describes each woman in turn and says they are different, which is an observation and not an argument.

Grading well means asking whether the essay explains what the contrast does for the novel, not just what the contrast is.

From Description to Purpose

The strongest essays ask why Plath placed these characters in Esther's path. They might argue that Doreen tempts Esther toward a freedom that turns out to be hollow, while Betsy offers a safety that Esther cannot accept. The essay then shows how Esther's reactions to each reveal something about what she wants and fears.

• The thesis makes a claim about what the contrast reveals, not just that it exists
• Each character is supported with specific scenes or lines instead of general impressions
• The essay explains how each foil affects Esther's thinking or decisions
• The student notices complexity, such as moments when Doreen and Betsy are not what they first seem
• The essay connects the character contrast to a larger idea in the novel

Scoring Complexity and Balance

Watch for essays that flatten characters into types. Doreen is not simply the bad influence, and Betsy is not simply the naive good girl. Students who notice the moments that complicate these labels are reading more closely and should be credited for it.

Also check for balance. If the essay spends three pages on Doreen and a paragraph on Betsy, the contrast is not really being explored. The rubric can include a line on integration to encourage students to keep the characters in dialogue.

Handling Joan as a Third Figure

Joan is a more delicate topic, since her role in the later part of the novel is tied to some of its darkest moments. If students write about her, remind them to focus on her function in the narrative and Esther's response to her, and to treat the subject with care in their language.

Comments on these essays should stay close to the text. Ask what Joan's presence changes for Esther, and how the reader is meant to understand the connection between them.

Efficient Feedback for Character Essays

The recurring comments on these essays are easy to name: move from description to purpose, add evidence for each character, and connect the contrast to the theme. Putting them in a rubric or comment bank speeds grading and gives students consistent guidance.

AI-assisted tools can flag the character-sketch pattern, and you can then focus your attention on the essays making original claims about what these women mean to Esther.
