Nick's letter to Olivia after he was sent to jail.
Keith, in general, is a sweetheart to diabetes-inducing levels. He's a dopey Man Child obsessed with rock 'n' roll and who vocally hates green peppers... Who also loves his wifeand children more than anything in the world, puts them before everything else in his life (yes, even his precious guitar), and who has no trouble at all treating the bizarre York like they're the oldest of friends. His sheer niceness is remarkably refreshing.
The entire ending for the Director's Cut. From the reveal of Zach having a family and living happily throughout his life, to finally being reunited with York and the Goddesses.
Despite everyone's wariness, York is surprisingly gentle and considerate when he questions the Ingram boys - one of the first signs that there is a softer side to him. Of course, it makes sense that he's decent with kids, given that York's been guarding a traumatized boy's psyche for the past couple decades.
