The Bear Enjoyer

“Fallen prey to his own beliefs [...] He’s a guy who’s resigned to his indentured servitude of being alive. But he despises the sentence and the penance. He will not accept defeat. He’s not going become a madman, he’s not going to kill himself. He wrestles the devil every day, and he realizes that this may last a lot longer than he ever hoped for.”

Because surface level Marty does in fact come across as an idiot, not to mention the fact that he is indeed a misogynist- but he is actually perceptive and intuitive. He knows when people are lying to him or when something does not add up. He knows how to connect the dots on case details. He knows how to manage people. When he puts interest into it, he can actually debate back at Rust very effectively. Those things take smarts.

Rust was Childress' bride. “Our death is our wedding with eternity” [X] I've seen the post obviously about Rust and Marty getting married in Carcosa, but the way that Childress is speaking to him. The way Childress spoke at the beginning of the episode.

"I'm busy. I have very important work to do. My ascension removes me from the disk and the loop. I am near final stage. Some mornings, I can see the infernal plane"

I take this to mean that Childress knows that he's about to die. And he's offering Rust to join him, both as a priest and as his bride. He refers to Reggie and Dewald as his lovers. He knows that Rust can "see" the circle. He plans for them to kill one another, thus joining them in matrimony to death, with Carcosa as the alter before the yellow king. "Take off your mask." Remove your veil? Anyone?

Rust's appearance is important here too. In a bright white shirt amongst the filth and despair of Carcosa's caging branches and desecration. It's both a bridal white and a Messianic figure, given the state of his hair and mustache. It's especially prevalent afterward when he's in the hospital.
