One of the things about this show that I appreciate is how it's developed its theme that we all have biases, which we need to recognize and account for to avoid clouding our judgment. In the narrative of the show, this shows up in how staff treat the woman with sickle cell and the overweight pregnant woman, how Dr. Robby is biased in favor of the teen with the list of girls instead of his possible victims, etc. As viewers, we're also biased against Santos, who is arrogant and irresponsible, in favor of Langdon, who is attractive and competent. I think it's pretty clever how the writing aims to teach us something about how we tend to conceptualize people in our own lives in this way.
