At first, Doris seems like a teenager at Ruby's school, however, she is soon revealed to be another extension of the devil and any time she appears on screen, Ruby is actually alone. Much like Miss Vera and Da Tap Dance Man, Doris preys on her target's insecurities. For Ruby, her worst fear is to end up like her mother and all she wants to do is fit in with her white classmates.
It's heartbreaking to see Ruby all alone as she thinks she's gaining acceptance from her peers during a cheerleading tryout. It isn't until she covers herself in white paint that she realizes there is something wrong with her "new friend." Much like Gracie and Henry, Ruby needs Lucky's help to defeat her devil. Doris tries convincing Ruby that it was actually Lucky that killed her brother and that she will hurt her too, but together, Lucky and Ruby reconcile and Doris ceases to exist.
