After reading countless posts (and continue to do so, I have a lot of catching up to do), I have noticed a few "symbols" or maybe foreshadows that I haven't seen discussed.
1). When J complains to E that Aguirre doesn't have right to get them do something against the rules. Sounds like foreshadowing the FNIT, where sex between men is against "conventional" rules. It was J that initiated the FNIT by placing E's hand on his erection.
2). During the campfire discussion between J and E about the value of bull riding, E makes a comment about what's the sense of riding stock for 8 seconds. When one looks at E during the FNIT, E mounts J and grabs onto his shirt with his left hand (with right hand free) and rides J for just about 8 seconds mirroring a "winning" ride. (noted in rodeo scene where Lureen is watching J's winning ride of 8 seconds).
3). Also now understand how J and L got married (or had to). Apparently, L became pregnant with Bobby in the back seat of her daddy's car (August 1966) and Bobby was born February 1967 (8 months prior to J/E reunion). Never quite understood why L would marry J unless she had to, and explains why LD Newsume hated J for not only being a rodeo cowboy but getting his darlin daughter pregnant (of course LD would NEVER think L was the aggressor and that he helped create the situation by wanting the car back by midnight forcing E L to have sex without protection, no time to go to the drugstore)
4) Finally dawned on me what E was doing with half opened bottle of white wine in his fridge, must have been left over from Cassie's visit, but damn it must be old and stale since it was at least a year between ghosting Cassie/bus depot and that scene with AJ. Hardly the drink to celebrate "my lil girl's getting married", but then again it's E, so what can one expect. I guess white wine (which is all she seems to drink) is her way of rising above the tiresome beer/whiskey drinking crowd she has to deal with every workday.
