 She is naive when it comes to certain topics - especially her birth mother, but she smartens up about her when finally realizing she was using her for money.She changes herself for guys and friends like in "The Morning After" when she sees that an old friend, Garrett is cute now and writes poetry, she goes to a Poetry Slam with him, and pierces her nose herself for him since he was hanging out with a girl who was dressed much edgier than Mariana.Also, in season 2, she dyes her hair blonde to fit in when making it on a dance team only to overhear the other girls say she only did because she is Latina.
