As a newer viewer, it's really interesting reading this after what happened to Heath.
I still think there is a lot to learn about the accident. We saw Cathy driving while they were chair dancing to the music. We never saw Angelica behind the wheel. Yet something happened between what we saw and what happened where the two girls changed places. I think that is what will ultimately get Angelica with a more lenient sentence. Maybe Cathy got terribly sick and Angelica was just trying to pull the car off the road. We don't know yet.
I like your story!!
