Ms. Boudreaux is a teacher from Truman High.
Ms. Boudreaux is the gym teacher at the school. She has a preference never to teach dodge ball because it is too dangerous for the students. In 2009, she goes in a leave in order to get married in Massachusetts. Dean Winchester, a former student, returns to the school to investigate a mysterious death, and decides to substitute for Ms. Boudreaux, whom he refers to as "Ms. B".
A student named Colby becomes nervous when Dean chooses to teach dodge ball despite Ms. Boudreaux's warning. Dean ignores Colby and teaches them anyway.
- The fact that Ms. Boudreaux is getting married in Massachusetts may imply that she is a lesbian, since Massachusetts was the first state to legalize gay marriage.
