Tim places the Lorelei mannequin immediately behind a curtain to the right. When Martin goes behind the curtain to find her, he continues through the curtain to the left as if nothing is situated to the right.
Martin tells Tim that Lorelei is in a state of frozen animation and can't hear what they are saying. Later, to re-animate her, it is required that she smell the aroma of a cologne. That would not be possible if she is frozen and not functioning.
