Macy Matlock is Claire's best friend. She's popular, arrogant, and outrageously nosy. Macy has a habit of pinpointing the worst characteristic of a person - whether real or imagined - and highlighting that flaw whenever possible, preferably to turn others against that individual. Macy is the first to accost Lani in the hallway, demanding to know whether he's a boy or a girl. It's clear that Lani makes Macy uncomfortable, but no one was expecting Macy to take part in his torment. Macy helps the Fish Frat steal a package from Lani's house, informs Claire's mother that she's leaving with Lani, and even steals Lani's nightgowns to hang in a public display of shaming.
