Though she prefers to chill and be one the guys, she can be very girly at times to. She isn't afraid to speak up for her self when she needs to. She can be a little bit of a loner from time to time, but she's always in a good mood. Though her and Tanner argue a lot, at the end of the day they have each other's back. She can be lazy, and sarcastic at times, but it's all with good reason.

Though he doesn't love the idea of living with the Landcasters or having a new step-dad watching over him, he doesn't express it to much. Tanner at the end of the day is a pretty chill and nice guy.
