its based on a book by mervyn peake called gormenghast. upon realizing that her heart had been broken, fucshia, now growing old, finds it too difficult to retreat back into her imaginary world. she plays in her mind with the idea of suicide. not really knowing what she is doing, she begains to act out a story once again. suddenly she is startled by a knock on the door. it is he who had broken her heart. but before she can gain composure and pull herself from her make believe, she slips on the window sill and falls to her death. drowning in the flood water outside.
