Oh noes!! I love and hate portrait fics because they tear me up so much! This is so sad and so well done. I often wonder how much a portrait can actually feel and think, and I hope that the answer is 'not much' because otherwise it would be a living hell to exist that way. And for the living to cling to the shadow of the person they loved so much by having a relationship with a portrait is especially sad. It's almost better if the person just died and made a clean break. Man, JKR created some truly horrific yet seemingly innocent things in her world.
