A Fixed Reflection or No Reflection
To be honest, the woman who sent Fridman such an ambiguous request deserved what she got. A drastic shift may not have occurred if she had requested that he remove the mirror. What on earth did she think she was getting when she said that?
Did she believe that Fridman would just erase her reflection from the mirror, giving the impression that she was a vampire in her twenties? Mirrors are obviously a mystery to her. Problem solved girl, no reflection at all, but Good luck covering the pipelines in the window.
