she was married to a Christian, they named him and then something happened and her husband or ex husband (she probably left him and he is the one indoctrinating the kid) is trying to make sure his kid remains a Christian: I think she is dropping him off at her ex's house and that's why the kid is so anxious and angry: he has to listen to more of daddy's explanation of his mother going to hell.
