Nate most recently called the police on Fez, after Fez told him to stop messing with Rue and Jules. Fez is, of course, a drug dealer—so last we saw, he was scrambling. Nate is clearly the series villain, and common thinking would have to see him receive some comeuppance in the finale.
It's possible Nate actually does have genuine feelings for Jules, but as of right now, he's unable to separate loving women from controlling them; to him, these concepts are one and the same. It's not the kind of love that Jules, or Maddy, needs. In contrast to Jules, Rue sees Nate exactly for what he is.
What follows is a sequence so experimental and hazy that many fans have speculated Rue might actually be dead. Euphoria creator Sam Levinson quickly clarified that she's very much alive — and although she's still struggling, she isn't dying anytime soon.
It's teenage Daniel (Keean Johnson), a grown-up version of Kat's (Barbie Ferreira) middle school boyfriend from “Made You Look.” The pair jumps on the carousel and Cassie simulates cowgirl-style sex on her inanimate horse as Daniel looks on, slack jawed.
Lexi is Cassie's younger sister and Rue's level-headed childhood friend who tries her best to support Rue through her struggles.
That's pretty clear when Rue describes feeling hurt that Jules cheated on her when she went to Los Angeles, but then proceeds to gloss over the fact, or not acknowledge, that the two of them never said they were dating. “Jules feels the pressure of Rue's sobriety resting on her,” Hunter Schafer noted in the featurette.
Cassie makes a comment in the finale about this being the first time in years that she's not in love with anyone, so it might be safe to assume that after her abortion, she and McKay broke up.
Jules is still on a high from her encounter with Anna, and Rue seems not jealous in the least. And later we get a fantasy scene from Rue imagining herself killing Nate and setting him on fire, about 10 minutes into the episode. So Nate died in a fantasy, but no one has died in the episode yet as of 10 minutes in.
Unlike other TV jocks, Nate's power trips come with layers of unresolved trauma. His calculating nature also sets him apart from the average 'roidy football player. He's not just aggressive; he's psychopathic. The first episode showed Nate flipping out in a fit of anger after seeing his ex-girlfriend with another man.
Though Jules hates Nate for blackmailing and threatening her, she has an attraction to him, as she is still in love with his "Tyler" persona. Nate seems to continue to have feelings for Jules as well, following her, watching her house at night, staring at her and complimenting her to Rue.
The installment, which also revealed Nate and Maddy's history, ended with the two embracing at a motel, apparently putting the dramatic ordeal behind them and attempting to be together in secret. Despite their incredibly dysfunctional relationship, Elordi tells TheWrap he thinks “Nate really loves Maddy — 100%.”
From everything in the show, I can say that Nate shows narcissistic traits that people without experience with mental illness may deem to be a Personality Disorder, but there is a stark difference is having narcissistic tendencies and a full-blown personality disorder.
So, Nate takes matters into his own hands, and beats Tyler to a pulp, nearly murdering him.
