After the murder of Moss in the El Paso hotel room in No Country for Old Men, we see Sheriff Bell (TL Jones) get into his car talking with the local Sheriff. They talk about Chigurh. The scene cuts to Sheriff Bell returning to the crime scene and going inside the hotel room where Moss was killed.
Why did he go back to the room? Was he anticipating Chigurh to also be there, as the conversation with the local sheriff hinted at it?
