Not sure what the point of this episode is. Getting together a bunch of hunters who don't bother to protect themselves against demon possession is just weak writing and frankly they all deserve to die. No story line just another demon, no need for Billy to be there, rather pointless all in all. No character development to speak of, Sam is Sam, Dean is Dean and Mary is just Mary a bad mother overall simping around the place feeling sorry for herself rather than making up for lost time.
