How many major characters does the story have? Why is the narrator called “Snot” by the other girls? What is Snot’s real name? When do we learn this? In the discussions about how to deal with the girls of Troop 909, what ideas does she present? Why does she not want to accompany the other girls as they go to meet Troop 909?

The major characters in the story are Arnetta, Octavia, Laurel (the narrator), Drema, Elise, Janice, and Daphne, members of an African American Brownie troop. These girls figure prominently in the story.
Snot's real name is Laurel. The text tells us that Laurel has been called Snot ever since first grade. She earned the embarrassing nickname unintentionally. Accordingly, after an especially violent sneeze, Laurel had splattered a nearby girl with mucus. In the story, it is Arnetta who first addresses Laurel as Snot. After suggesting that their Brownie troop beat up the white members of Troop 909, Arnetta warns Laurel (Snot) against telling Mrs. Margolin (one of the troop leaders) about the plan.
Initially, Snot does not approve of Arnetta's plan. When Arnetta suggests that their troop must catch the white girls alone, Snot argues that it will be difficult to do this. She maintains that the white girls will only be unsupervised during bathroom breaks.
We can see that Snot is reluctant to participate in Arnetta's plan to beat up the white girls. She tells Arnetta that she prefers to stay behind. However, Arnetta's answer is an unfeeling "No, Snot. If we get in trouble, you're going to get in trouble with the rest of us." At every step of the way, however, Snot tries to get her fellow troop members to pull back from their foolhardy mission. Despite her efforts, however, the plan moves forward. In Snot's mind, none of her fellow Brownies have considered the possibility of the white girls fighting back.
So, Snot is reluctant to accompany her peers to meet Troop 909 for a few reasons. First, the textual evidence indicates that she is not convinced any of the white girls used a racial epithet to address Daphne. Second, Snot does not think that beating up the white girls will accomplish much of anything. She thinks that it may even get their whole troop in trouble. Third, Snot feels uncomfortable at the idea of fighting, even though she believes that she should remain loyal to her troop.
So, as a first-person narrator, Snot provides us an intimate view of how racism is processed from a young adult perspective.
