The person responsible for cleaning up the car after Marvin is accidentally shot in "Pulp Fiction" is Winston Wolfe, commonly referred to as "The Wolf". The Wolf is a professional cleaner, meaning he's an expert at solving messy problems, particularly those associated with criminal activities. His character is portrayed by the actor Harvey Keitel. The event of Marvin being shot is critical to the plot as Vince (John Travolta) and Jules (Samuel L.Jackson) were returning from a mission when Vincent accidentally shoots Marvin (Phil LaMarr) in the face. They take the bloody car to Jules' associate Jimmy's (Quentin Tarantino) house. According to him, the car needs to be gone before his wife comes home, to avoid trouble. In comes The Wolf. He is known for his professionalism and efficiency. He lays out a plan for them, instructs both Jules and Vincent on what to do, which includes cleaning the car, disposing of Marvin's body and the clothes. This scene does two main things for the story and themes of "Pulp Fiction". Firstly, it showcases an unexpected element of hazard in the life of the professional criminals. The fact that Vince could accidentally kill Marvin, someone they were supposed to save, also adds a layer of dark humor which Quentin Tarantino is commonly known for. From a thematic perspective, this situation brings home the reality and chaos of the criminal world. It serves as a stark contrast to the otherwise cool demeanor of Jules and Vincent, showcasing that they can also be unprepared and chaotic. The Wolf's precisely handled cleanup helps to display the underlying structure within this chaotic criminal world. Furthermore, while Jules starts questioning his life as a hitman after the "divine intervention" event, Vincent’s carelessness ends up in Marvin's accidental death, underlining the disparity in their character arcs. Lastly, this sequence is a brilliant exhibition of Tarantino's non-linear storytelling, and the interconnectedness of his characters, who seem to run into each other's lives purely serendipitously. This allows for tension and uncertainty in the story, as well as propels the narrative forward in unexpected ways. Therefore, the aftermath of Marvin's shooting plays a crucial role in the comprehensive understanding of "Pulp Fiction".
