- Act One
- Act Two
Chandler and Duke's relationship is complicated and they don't get along. Whenever Duke speaks, Chandler always tells her to shut up harshly. In the song "Beautiful", Chandler said "Grow up Heather, bulimia is so '87." Chandler was implying that Heather Duke should "grow up" from this "eating disorder trend" showing she doesn't care for Duke's eating disorder and just calling it a "trend". In Blue (reprise) (or "Never Shut Up Again") after Chandler's death, Duke took Chandler's red scrunchie (In some productions, Duke also changed her clothes from green to red) showing she is now the new leader of The Heathers and it is clear she isn't showing any respect to Chandler.
McNamara and Duke's relationship is complicated. In the song "Beautiful", McNamara said "Maybe you should see a doctor, Heather." (In West End, she says "What you need, Heather, is to see a doctor.") showing she has a little more sympathy for Heather Duke. However, throughout the rest of the play, Heather McNamara continues to ignore Heather Duke and disregard Heather Chandler's abuse against her. In Act 2, "Shine a Light (Reprise)" Heather McNamara's suicidal thoughts take form as Heather Duke and her other classmates, signifying that Heather McNamara is scared of Heather Duke and the power she now has.
