Supernatural - Live Free or Twihard

Another great episode.  This one is about vampires and as much as I love Twilight I found it funny that they were making fun of it.  Sam and Dean start investigating teen girls disappearing.  We find out that they are being recruited via a vampires site since the vampire appeal is hot right now.  They must find the nest and in the process Dean is given some vampire blood while Sam stands by and smirks.  So it looks like Sam let that happen to Dean.  But Samuel had told Sam that there was a cure as long as Dean doesn't ingest human blood.  It involves injecting a vampire with dead man's blood and making a drink.  Dean of course goes and visits Lisa and Ben and scares the crap out of them.  Then he gets into the nest and finds out that the vampires are getting their orders from an Alpha who is building an army.  Dean gets cured and remembers that smirk that Sam had and knows he let it happen.  So now Dean is really suspicious of Sam.
