Tropes associated with her work:
- Dawson Casting:
- Dyeing for Your Art: She had brownish hair with blonde highlights when she was cast as Cordelia - the same colour as her female co-stars Sarah Michelle Gellar and Alyson Hannigan. Hannigan went redhead while Carpenter went dark brown.
- Hide Your Pregnancy: Initially on Angel - with long coats and lots of black helping it along. Eventually her character's secret pregnancy became a plot point. But notably after giving birth, Cordelia only appeared unconscious and from the shoulders up (as Charisma hadn't given birth yet).
- The Red Stapler: She's been told numerous times by fans that they named their daughters Cordelia in honour of her character.
- Separated-at-Birth Casting: Her role as Sutton and Emma's birth mother on The Lying Game was supposed to be a secret but everyone figured it out due to Carpenter's uncanny resemblance to Alexandra Chando.
