Something I haven’t really seen talked about is how the Undersiders mirror Taylor’s bullies.
Obviously, each member of the trio torments Taylor differently: Madison creates little annoyances and pranks, Sophia is animalistically violent (predator-prey) (obviously this is part of the bad racial politics of worm) and Emma engages in psychological warfare based upon specific knowledge of her victim.
Meanwhile, in the Undersiders, you have Regent, who causes little slip-ups in his opponents, Bitch, who is animalistically violent (dog) and Tattletale, who engages is psychological warfare based upon specific knowledge of her victims. And in Grue, you have a Mr Gladly; an authority figure who is meant to reign his charges in but whom fails utterly after making only token efforts.
And Taylor is completely fine with this! I don't think she even really notices, let alone cares, because, with the exception of Bitch (whom she establishes dominance over), this isn't turned against her. Taylor holds a knife to Amy's throat while Tattletale threatens to ruin her life, and she doesn't even have a second thought.
