Sisterhood, Loyalty, White Cop
In both Thelma and Louise and Set It off, sisterhood and loyalty are established through surviving hard times together. Thelma and Louise fight to break free from an unhappy marriage and fight to get through the attempted rape. The women of Set It Off make it through Frankie's robbery accusation and financial downfall, Stevie's death, and Tisean's battle with child services. Thelma, Louise, Frankie, Cleo, Tisean, and Stoney all set out on an adventure in search of a better life.
The white cop functions as a "good cop" in both films. In Thelma and Louise, the while cop tried to save Thelma and Louise and get them out of trouble. In Set It Off, the white cop pursues the women, but he also tries to stop them from harming themselves and tries to help them find a way out. He lets Stoney go at the end of the film, knowing that she is on the bus. I think he felt guilty that her friends had all been killed and felt he owed it to her to let her free.
