They submit to everyone

Luna and Hermione stand in silence, without a thought crossing their minds. Perpetually aroused, and yet unable to act without another’s input, they sway idly throughout the night. No spark of imagination flickers in their blank eyes, they have become mere receptacles for the desires of others.

They wait without emotion for orders, not caring about consequences. Any suggestion that they hear is a powerful command to them that they simply will fulfill, no matter what they would have thought a few minutes ago. Their old selves are effectively gone, crushed into the dregs of their minds by the overwhelming onslaught of looped curses.
