SAM AND DEAN MEET ANNA, A GIRL WHO CAN HEAR THE ANGELS - Ruby (guest star Genevieve Cortese) tells Sam (Jared Padalecki) and Dean (Jensen Ackles) that a powerful demon named Alastair (guest star Mark Rolston) is searching for a girl named Anna (guest star Julie McNiven) who can hear the angels' conversations. The three set out to find Anna but once they do, Alastair attacks them and Ruby escapes with the girl. Believing they were set up, Dean lashes out at Sam for trusting Ruby, so Sam tells him what happened during those months Dean was in Hell and how Ruby saved his life. Castiel (guest star Misha Collins) and Uriel (guest star Robert Wisdom) return and demand to be taken to Anna but not for the reason Dean thinks.
