Tear Jerker / East of Eden

• Pretty much the third act of the film, but the scene where Cal hugs Adam in a sobbing mess is hard to watch. Bonus points for it being unscripted.
• There's something very sad about the fist fight between Aron and Cal. Mostly because Cal jumped into the mob fight to help his brother but, when Aron puts two and two together and realizes he and Abra were at the fair together, he attacks Cal violently. Fridge Horror says that Cal did have affection for his brother, and this is yet another moment where someone rejects his love.
• When Cal shows Kate's house to Aron. Kate looks up and sees her son there, she says "Cal" in a way that makes it sound like she's happy her son came back. But he's just there to hurt his brother, acting as a Heel–Face Door-Slam to both of them.
• The narrator making it clear from the beginning that Cathy never could have lived a normal life, having been born without a conscience or the ability to love. Throughout her life she finds no real joy in anything and expends all of her energy manipulating, hurting, and killing other people for personal gain, yet none of it makes her truly happy. In her later years, she comes to realize that everyone around her has something she doesn't—she never figures out what it is, but she knows it's the only thing that really matters. For all of her wealth, beauty, and (eventual) power, she can never change who she is and always will be: an Empty Shell of a human being who has nothing worth living for and no one who matters to her. As she prepares to die alone by taking a lethal dose of morphine, she imagines shrinking smaller and smaller with her Imaginary Friend, Alice from Alice's Adventures in Wonderland—the closest thing to a real friend she's ever had.
