Charlotte was committed: not sure if this is a spoiler or not, but:
Charlotte has to be the cam girl when watching porn. I was a bit surprised that Rachel didn't innocently rat her out past a certain point (football related). I, too, want to see all the girls developed. Including Tia. And since you are a big April fan, "Abbie" which one assumes is the name of the rounder girl Cassandra Cassandras in the showers.
