Danneel Ackles and Genevieve Padalecki are returning for episode 13 of the final season of Supernatural!
As the episode description puts it, "A search for the one thing that may give the Winchesters an edge against God leads Sam (Jared Padalecki) and Dean (Jensen Ackles) to Jo’s (guest star Danneel Ackles) door and to a secret that may have died with Ruby (guest star Genevieve Padalecki). Meanwhile, Castiel (Misha Collins) asks Jack (Alexander Calvert) to do the unthinkable to help the brothers in their quest."
Will you be glad to see Jo and Ruby one last time? What secret died with Ruby? What unthinkable thing does Cass ask Jack to do? Tell us in the comments or in the discussion thread for episode 13.
