Scent in Rituals

Another aspect of  sacrifices may be the smell that Rust notes in some scenes related to the sacrifice. In the Navajo religion, scent and odour can also be important components as these are used in ritual lotions. However, Rust makes a note before finding Dora Lang's body and also arriving at Earl's location (these take place in the first and final episode, respectively). Rust says that he can taste ash and aluminum both times. As the Tuttle cult may follow a mix of religions, they may use a special lotion for these ritual killings, which Rust can smell. This is still just speculation as viewers cannot smell through the screen (10).
