Raina and Amara bonding by making jokes about Nevada, the silver state. "Looks more like the brown state".
Even if they don't really pay much attention to her, Lindsay and Raina's other cousins are pretty decent to her. It's clear that they don't hate her but merely don't know/are unable to connect with her.
Amara's relationship/love for animals. First sign that she has a strong heart of gold underneath all that grumpiness.
The ending. Raina finally realizes that she's been blind to her parents' failing marriage due to her escaping reality with her Walkman. After agreeing to help Mango in exchange for batteries for her Walkman, Raina goes to put her Walkman back on ... but turns to look at her little sister and takes the headphones off. Amara is visibly touched by this. The last few panels show Raina reading from Amara's atlas, laughing at one of Amara's jokes, and the van driving back home. It's a surprisingly sweet and meaningful ending.
