Not much is known about Buck's past, other than the fact that he used to tend bar in South America, which was referenced in Episode 7, "Full Moon (Creepy AF)". In the pilot episode, he was initially fired due to him having intercourse with multiple women, including one of the patients he had to help that same episode. Although he is brought back into the job, he occasionally clashes with his boss, Bobby Nash. Over time, his relationship with Abby Clark grows and eventually, they grow to be a couple, although they are 16 years apart in age.
- He has a birthmark on the left side of his face, which is mistaken for a bruise of some sort in the first episode, "Pilot" by one of the women he is fornicating with. In real life, Oliver Stark actually has this birthmark.
