[Sanji doesn't know that voice, but the tone of it freezes his heart in his chest; he knows the rage behind it all too well, has heard it from exactly one person in his life and that one person is the source of more pain and woe than all his siblings put together. This person is angry, and poorly restraining that anger, and even with the locksmith puzzling away at the back of his head, he tries to shrink away, as if he could hide himself behind nothing but himself.
