Smile Lines

Fiorella's post-surgical face was a blank slate, like a mask, but the character is starting to return.  For "character," read "smile lines," and Fio wants to keep them.  After all, they're inherited from her father, and they were one of the most beautiful things about him.  Even into his nineties, his smile  announced his pleasure with life, his joy with the world,  his good will to all. 

It also took years off his age.  Yes, Dad's facelift was natural.
