Who is Duane from Wasted: A Memoir of Anorexia and Bulimia and what is their importance?

Duane is one of the most important people in Marya's recovery because it is with him that she makes a true emotional connection. Duane tempts Marya to first spend time with him by offering to play rummy with her. After this game, Duane asks Marya if she will be his sister while they are at Lowe House together. Marya agrees. Duane chases Marya to the door of her room one night when hugs are being given. He asks permission to give her a hug. Duane is also assigned to Marya to help her learn how to play.
