BENNY CALLS DEAN FOR HELP — After Benny (Ty Olsson) gets brutally beat up by some vampires, he calls Dean (Jensen Ackles) for help. Dean abruptly packs up and tells a confused Sam (Jared Padalecki) that he’s taking a “personal day.” Benny confesses that he’s going after his Maker (guest star Patrick Stafford) so Dean offers to help, flashing back on the many times Benny helped him and Castiel (Misha Collins) in Purgatory. Meanwhile, Sam (Jared Padalecki) uses his solo time to reflect on the life he left behind with Amelia (guest star Liane Balaban). However, when things go bad for Dean and Benny, Dean calls Sam for help, which makes everything very complicated. Guy Bee directed the episode written by Ben Edlund.

@Leonie: Sam mach learning by doing in dem Fall kennenlearning by helping. Dean hat ihm ja nicht die Bohne von dem ganzen erzählt.

Da sich Dean und Benny schon in die Sch**** reingeritten haben und Dean einen Hilferuf an Sam schickt, wird der wohl zuerst handeln müssen, bevor er ne Antwort bekommt. So denk ich mir das. Auf den ersten Blick sieht Benny auch nicht aus wie ein Vampir. Woher sollte Sam dann auch sofort wissen WEM er da jetzt beisteht.
