Episode 6 of "The Last Night at Tremore Beach" kicks off with the vibrancy of Tremore's carnival, where masked parades flood the streets as the community converges in festive spirits. Amidst this, Alex gears up for his eagerly anticipated solo concert. He reaches out to Leo and Maria, but they remain aloof, their wounds from the past still fresh.
Alex's eyes catch a glimpse of a red van—the same one that has haunted his visions—and he bolts after it, his heart pounding. However, his chase leads him to a troupe of performers, and the van's true identity is revealed. Later, Alex seeks Maria out once more, and she lays bare the hurt he's inflicted upon them. Yet, she whispers a poignant reminder that everyone deserves the chance to start anew. They part on more amicable terms, with Alex once again inviting the couple to his concert.
Meanwhile, Bruno grapples with visions of the "monster" he once encountered in a cave. His nightmare materializes during the carnival, as he spots one of the masked performers wearing a devil's mask.
As Alex's concert kicks into gear, he dedicates his performance to Leo and Maria, referring to them as his "angels of Tremore." Touched by his gesture, they forgive him and attend the concert. Alex plays a song he composed for Judy, and the audience erupts in thunderous applause. Judy, moved, names the piece "Tremore Beach."
During the torch-lit parade that evening, Alex spots the enigmatic man from his visions again and dashes after him. As the man flees in a red van, Alex manages to snap a photo. Alex's father trails him and later unearths a stunning secret about Alex's mother.
After Alex's concert, his mother had somehow obtained Estrella's car keys and coerced her into driving her home. During the ride, she pressured Estrella to relinquish her scholarship to Alex. Estrella, out of respect for Alex's wishes, refused. Enraged, Alex's mother caused the fatal accident that claimed Estrella's life, leaving her to perish on the roadside. Following the tragedy, Alex's parents agreed that his mother should be confined to a sanatorium for the remainder of her days.
The episode draws to a close with Alex, utterly shattered by the chilling revelation of his mother's involvement in Estrella's tragic demise.
