Sam is the main supporting role. As the lead's (Madelyn) best friend, she has quite a few lines. In one of the last few chapters, the point of view changes to her's and will require narration.

Sam can be witty and sarcastic when around people she's comfortable with or as a way to not show how uncomfortable she is in certain situations. She's a teenager, and as one, I don't know any teenagers who aren't smart asses from time to time. Also like a lot of teenagers, she's stubborn. She cares a lot about her friends and what they think of her, which means it hurts her more if they fall out or something goes wrong between them. She's sensitive and wears her heart on her sleeve, which she kind of compensates for with her weird one-liners that are spotted through her dialogue. She can get pushed off the edge very easily and can get frustrated with very small things. Other than that she is really bubbly, and positive, which is most of the time. Her voice would typically reflect this, it'd be bubbly, higher-pitched, and cheerful but sombre when necessary. Feel free to experiment though.
