Supernatural - I Know What You Did Last Summer

So I read up a little on the show so I could have a type of thread to go on, and I Know What You Did Last Summer was chosen, admittedly, for the title. Yeah, I'm easy. This basically covers Sam explaining to Dean why he associates with demon, Ruby, and how she helped save his life and vice versa. Ruby inhabits one body, and Sam insists she go into a vessel that doesn't have an ongoing life. So Ruby chooses Genevieve Cortese, because she's listed as Jane Doe in a hospital with nothing left but being kept alive by ventilator. Ruby instigates Sam's drawing power from demon blood kept in a flask. Relying on it becomes an allure Sam will have to overcome. Introducing the beauty, Julie McNiven, as Anna, held in a metal hospital for "hearing voices". It turns out that Anna can hear the voices of angels in Heaven! Yeah, that talent is of particular interest for those in Hell, especially a nasty, all-powerful demon named Alistair. Nice to see Mark Rolston, an actor of prolific characters, as agents, suits of the corporate world, and every kind of heavy. He fits the menace of a demon of magnificent strength, with a body of a pediatrician yielding the vile, opportunistic Alistair. He mistreats Sam and Dean with special relish. Sam, shown sewing up a grisly gash, and Dean needing his dislocated shoulder adjusted; the ill effects suffered when hunting demons and preventing Lucifer's release. Anna flees from her hospital room before a demon possessed orderly can get her, retreating to her minister dad's church as refuge. As a supposed sanctuary, Alistair and Ruby occupying the church says a lot about their power. So there's back story from Sam about fighting demons with Ruby, and his practicing drawing out demons from possessed humans. And Sam admits they had hot sex which Dean groans about obviously. Dean met Alistair in Hell and his freedom from there is mentioned in conversation, but this is not a topic of intense focus for this episode. Sam in his fearless state of attacking demons recklessly is tempered by his association with Ruby. Ruby's target is Lilith. Lilith has her soldiers out there. Angels, appearing at the end, don't mince words...they need Anna and tell the Winchester boys she's to be killed! I could stare into McNiven's face and eyes for ours...God, what a beautiful woman. Don't want to leave out that Anna occupied her time in her room by drawing from vision certain images important to the series' narrative which I thought was a clever touch. And Mary's sculpture bleeding from the eyes being a sign of demon approach marks for another clever bit of effect.
