Cinnabar stalks after the illusion and into the elevator, continuing her dance. When the illusion goes still on reaching the end of its instructions, she circles around it, scrutinizing without touching.
Her cold expression shifts to one of bafflement as it remains opaque to her sight despite her strong suspicion of it being illusory, and tactile when she lightly taps a leg with her toe to avoid interrupting the dance.
"Not an illusion... Then how were you caught without facing me? An Arcane Eye?" She mutters under her breath, inaudible to normal hearing.
The double of Weiss is subjected to further inspection, checking the designs of her jewellery and nodding in recognition.
"Protection and Splendour..."
Satisfied, she moves around to back behind the illusion with one last flourish of the saber to conclude the dance, then drags the serrated blade of the other across the double's throat in a vicious sawing motion, her knee against its back for leverage!
