Continuity mistake: At one point, Max mentions that she and Chloe made a mix-tape CD when they were both twelve. However, Max's journal in the game notes that Chloe is a year older than her, making Max's statement about them both being 12 when they made the mix-tape impossible.
Trivia: Chloe wears a necklace that's made of three bullets throughout the game. This is commonly viewed as either representing the three people who "abandoned" her and thus hurt her (her father, Max and Rachel Amber), or representing three times Chloe is murdered during the game - When she is shot by Nathan at the start, when she is shot by Jefferson in chapter four, and when Max can chose to sacrifice her to save the town in Chapter Five.
