'Supernatural' recap: "A Metric Ton Of Worst"
But that's beside the point, I suppose, because it's at this juncture that Bobby runs into his very own personalized Reaper, who explains that Bobby's in a coma, likely to die, and is thus running through the "gin-soaked rat maze" of his brain in some sort of review of his life's greatest hits before he finally flatlines for good. Naturally, because Bobby must impart that urgent set of Leviathan-related numbers upon Our Intrepid Heroes before he dies, he enlists the aid of Flashback Rufus to trap his personalized Reaper in The Flashback Emporium, after which he and Rufus stomp off in search of Bobby's Worst Memory Ever. You see, according to Rufus, once Bobby confronts said Worst Memory Ever, a magical path will open from Comaland to the real world, which will allow Bobby to speak with the boys one last time. Just go with it.
So, Bobby and Rufus run through a couple more of Bobby's Greatest Hits until they reach the night when a ten-year-old Bobby shot his violently abusive father dead in the middle of The Emporium's kitchen, just as the nasty old drunk was about to wallop Bobby's hapless and God-fearing mother into the middle of next year. And, as promised, after Bobby finally reconciles himself with what happened that particular evening, the magical path opens, and Real World Bobby wakes up long enough to scribble those important numbers on Sam's gigantic mitt, after which he calls both Our Intrepid Heroes "idjits" one last, affectionate time before biting it, for good.
