reminiscent of face/off although i don’t get all the visuals.’

This ficly and the prequel are a bit obsessively odd and peculiar. It seemed that the character took the “face off” part a bit nonchalantly when compared to her obsession with the other girl’s
smile.
“I wasn’t she.” came across as a little weird, though I think that’s the feeling that you seem to want to express.
Also, minor grammer edit: it should be “vase of flowers”… needs to be pluralized.

and it wasn’t what she had hoped, the new face.. but death? such a dark turn from the previous, I almost wouldn’t tie them together. this is surreal.
