After Hobart is shot, Coutelle sends Ray out to surveil Grampa's house. Crow Horse rides by and flips Ray off, as is his wont, then takes off with Grampa, so Ray follows.
At the powwow, Crow Horse is hanging back with Grampa, watching the dancers, when I guess he notices Ray's commandeered truck. Ray's sitting in the cab with Jimmy, but Jimmy, sensing the oncoming snark storm, or maybe just getting hungry, abandons Ray.
CROW HORSE: That's a nice truck, Ray, where'd you steal it? (leans against door) Thought you might want to see this.
LEVOI: What's going on?
CROW HORSE: (surprised) It's a powwow.
I love Crow Horse's tone of voice, here. At the beginning of the movie, when Ray and Coutelle are going over what Ray thinks is the crime scene, Crow Horse asks Ray in Lakota when they can bury Leo, and Ray is like, "Come again?" So even though Crow Horse knows, for real and for true, that Ray is only there as a PR thing and that he doesn't know shit about being Indian, he's still a little surprised, but he's not mean about it.
CROW HORSE: Bet that eagle feather you found gave you a little chub, didn't it? Well, we all have feathers from the same eagle. We share everything (touches the sunglasses) on the rez.
LEVOI: Those are my sunglasses!
CROW HORSE: (shakes his head) I traded Grampa.
Again with the discussing of the state of Ray's dick! In my secret favorite scene, the fraternizing scene where Crow Horse explains about the sign, the tracks Yellow Hawk left when he was ditching Leo's body, Crow Horse insults Coutelle and then does his fancy deduction trick, tells Ray his weight and how he eats and the kind of shoes he wears, and Ray says, "Fuck you," and Crow Horse mutters, "Yeah, you'd love to."
LEVOI: I'll trade with you. (offers Crow Horse the rock he got from Grampa)
CROW HORSE: (laughs) That's a rock. Ya nuts? These are Raybans. (walks away)
LEVOI: Jesus. (follows)
Crow Horse knows a bad trade when he sees one. Ray grabs his suit jacket before he follows after Crow Horse; he's lost the tie, but he's not ready to go completely dressed down.
CROW HORSE: You ain't got nothin' on Jimmy, do you?
LEVOI: You're no cop. Fleeing justice, assault with a deadly weapon, assault with intent to kill is nothing? Sedition! That scum is an enemy of the United States.
CROW HORSE: You know, Ray, when we were kids, we used to play cowboys and Indians? I was always Gary Cooper. I didn't want to be an Indian. Government boarding school made sure of that. Cut off my hair, washed my mouth out with soap when I spoke my own language. My own language, Ray. (Ray meets his eyes) When the A.R.M. warriors came here it was like an awakening. Got the people proud of their heritage, their elders, the language. And you call them enemies. Tough call all the way around, ennit, Ray? You just keep on doing that. Tomorrow morning I'll have Leo's murderer in the Bear Creek tribal jail; screw your jurisdiction.
LEVOI: Listen, if you're withholding evidence, you're in deep shit--
CROW HORSE: So sue me.
This is the most personal information we get on Crow Horse's backstory, but it's really well done, and Graham Greene sells the hell out of it: he's angry, and he's tired of having to explain these things to Ray that Ray as an Indian should already know.
MAGGIE: (picking up Hobart) You're a big boy!
Sheila Tousey does so much in this movie with just the expression on her face. A lot of scripts would have gone for awkward conversation or declarations, Maggie suddenly completely accepting Ray because of the way he helped Hobart, but this quiet moment feels true and unforced. Lovely.
YELLOW HAWK: Nice to run into you, Wash--
LEVOI: Yeah, yeah, the Washington redskin. (fiddles with the stone) How are you, Yellow Hawk?
YELLOW HAWK: Man, you better watch yourself. Round here, I'm the FBI: full-blooded Indian.
CROW HORSE: (beckons)
Poor Val. This bit with the rock is the closest he gets to his trademarked
I need something to do with my hands maneuver.
CROW HORSE: Grampa.
GRAMPA: (touches his wrist)
CROW HORSE: (laughs) Uh, he wants to trade. He likes your watch.
LEVOI: (laughs) Oh, no, impossible, because -- this, uh. . . grandmother gave it to me, when she was dying. Explain that.
CROW HORSE: Yeah. (speaks Lakota) Rolex.
GRAMPA: (offers broken cigarette)
LEVOI: No way.
GRAMPA: (Lakota)
CROW HORSE: He says you need to go on Indian time! White man time will give you stomach cancer.
LEVOI: (smiles) No deal.
BUT SERIOUSLY THEY ARE MARRIED. Another remarkable thing: Ray smiles!
LEVOI: Look, I don't know who you're after, but I'm not looking for a white guy.
CROW HORSE: Good, 'cuz neither am I. It's an old Lakota belief that if you turn a dead man upside down his spirit won't come back. Now that's a Sioux thing a white man wouldn't know.
LEVOI: Look, if you know something you better tell me. I can help you, just tell me what you know!
CROW HORSE: I won't really know anything 'til tonight. They're coming to Grampa's.
LEVOI: Who's "they"?
CROW HORSE: They are.
LEVOI: Who?
CROW HORSE: Well, you can either come to Grampa's and find out for yourself, or, uh, you can go and chase Jimmy! (points behind Ray)
Here are more things Ray doesn't know because he's only Indian enough for government work. He doesn't know about the journey, but he learns, and of course he remembers that when they find Maggie, face down in a shallow grave.
