The setting created the mood of the story because they either were in a fire, in the hot car, or the grandmothers house, they're sad at the fire, bored and miserable in the car, and happy at their grandma's.
The way the settings change the characters is that when they're in the car they're quiet of more then one reason, but then when they get to their grandmothers house they get happy, well most of them do, but their sad and depressed at the burnt house.
The main character evolves within the plot because in the first part she didn't care for her dad, but when he came back she hugged him and loved all over him.
The conflict in the exposition is when their house burns down, and they have nothing left.
It addresses the conflict by saying "Sometimes it's better to rise up out of the ashes, singing." and she's referring to the fire that happened and the phoenix, now in my opinion I think that the Phoenix was the reason for the fire.
The most influential event changes were when the phoenix came out of the egg and burnt her finger as well as when the father came home.
