High atop a cliff sits the mansion known as Shadows House, home to a faceless clan that pretends to live like nobles; they express their emotions through living dolls that also endlessly clean the home.

The adult shadows continue watching the debut candidates navigate the garden labyrinth; Shaun and Ricky have another tense encounter, and the dolls try to rescue their masters.

Kate and Emilico's fate hangs in the balance as Edward's carefully staged debut heads into its grand finale; Shirley and Rum have a breakthrough, but it could be too late; meanwhile, the third-floor shadows continue to question Edward's methods.

Kate notices a change in Emilico and upon reading her notebook, she tries something to help her, but Emilico vanishes after learning a secret; Kate enlists John in finding her and then shares the secret with the others.

Emilico finds herself in a bind, and Kate and the other children hatch a plan to slip into Lord Grandfather's wing to save her; Edward desperately tries to find out what Kate is up to, and the children finally learn the reason behind his plan.
