Goodbye, sweetie

river song calls the doctor to her side. unfortunately, he doesn't know her yet. They go on an amazing adventure to go back in time, break a time lock, prevent a flow of evil psychotic time lords and daleks escape, and rescue one thing that could save us all from certain death- unfortunately, its on gallifrey. the doctor struggles to trust River Song and river must grapple this will probably be the last time she sees him.

hey!! sneak peek- 'Do we even know what this 'world saving thing' is?' 'nope, not really!' they spun into the room where it was hidden. it was.. empty. except for a misty, robed figure. she glowed golden. she lay on her knees, shrouded in silky, plain cloth and mist. her hands covered her face, which was bent downward. she raised her head, hands slowly coming away from her face. she was a pale blue. strange designs webbed her skin.--- who was the mysterious lady? why is she dangerous? why is she glowing? why is she shrouded? why is she kneeling, and covering her face?
