A quartet of girls who appear to be sisters, but in real life, are not. They all look out for one another and help each other out. Though sometimes they make mistakes, they forgive each other! As modeled after Snape from Harry Potter.
Youngin 1: "Hey are you four sisters?"

Frowny Four: "YES!"
(even though this is false, they are a frowny four)
