How does Marguerite develop during her time in the junkyard?

The junkyard seems like an ideal refuge for Maya; she is among a group of people her own age and makes many friends, which she hasn't done too often. Again, the theme of abandonment which could have taken over the story after the last episode with her father is avoided. And there is a certain dramatic irony in the fact that when we'd expect Maya to be in a position of loneliness and hardship, she actually feels more secure and befriended than ever before. She sheds her naivete, and her melodramatic tendencies, and any self-righteousness she has; she becomes more adult during this episode, and more at home with people.
