He wants to get her a mirror.
The burden of the beauty he beholds everyday is too much to bear alone.
He needs her to share in the mystery and wonder of her own existence so he can make sense of it, or at least feel accompanied on such an overwhelming journey.

Those portals into the unknowing masked as safe reflections unsettle her.
Tapestry covered mirrors are tolerable with their icy fear slightly softened.
No poltergeist will get through here, thank you very much.
And the eternal enigma therein waits patiently to see herself being seen.
