i love this episode . it be a complete nail biter and and edge of your seat kinda deal . from the re appearance of gordon and who by the way in my eye be a fantastic villain and to the apparent disappearance of ava . it be fantastic . jensen ackles performance be again spot on . from his first fight with gordon and to the soul split wouldeath of sam and he be brilliant . just the right amount of action and mystery to make it a fantastic episode . kudos to the writer and and of course to the brilliance of kripke . ava be a brilliant character and just the right amount of angsty why me behaviour and couple with a bubbly personality to make a refreshing addition to the episode . all in all a fantastic piece of work and and one of my favourite episode . and while i be here can i just add how much i love that blood splatter on the camera when sam blow up representd xsarahx .
