Annoyingly enough, even though Dean went traipsing around this secret and large experiment room, Sam has appeared out of nowhere, suddenly lying right next to where this Zombie Death Fight just went down so that the brothers can conveniently rouse their injured bodies and bandy about some witty ripostes. "You're not gonna try and kill me, are you?" "No." "Good. 'Cause that would be awkward."The brothers bid a fond dawn farewell to this week's useless extras, advising them, "No more haunted asylums, okay?" Seriously. They turn toward the Metallicar and Sam delivers the least sufficient apology ever devised: "Hey Dean, I'm sorry, man. I said some awful things back there." Apparently, Daddy Winchester did not teach him the little-known companion to the old adage of "sticks and stones." The one that goes, "Call me whatever you want, just please don't shoot me?" Dean expresses surprise that Sam remembers what happened in the asylum. Sam says he just couldn't control it, but that he didn't mean any of it. Dean doesn't believe that. Sam assures him that he really didn't mean it -- whoops! my finger accidentally pulled the trigger! -- but Dean still looks unconvinced. When Sam snottily asks, "Do we need to talk about this?" Dean says, "No, I'm not really in the sharing, caring mood," and tosses his bag in the Metallicar.
Hotel room. Dean slumbers with one lusciously naked arm out of the covers, as the camera pans over to Sam's bed. Dean's cell phone is going off, but he stays asleep, so Sam reaches over to answer it. He says, "Hello?" and then sits stick straight up in bed: "Dad?"
And now we wait.
