The finish line. At this stage of every Supernatural season, we inevitably come to the approach of the season long finish line. Sam and Dean must face their season long foe---be it Azazel or Lilith or the Mark of Cain. Sam and Dean are racing against time and a foe with the hopes that when they finally defeat said foe---this season in Amara and Lucifer---that they can finally take some time and perhaps move forward. It never seems to work out that way for the brothers, however. In “The Chitters,” the Winchesters are confronted with that very question. What will do they do after they've completed the task of defeating the Darkness? What will “living” mean for them afterward? Most likely---taking show history into account at least---that future will mean facing yet another foe. And yet, one can't help but take in this case, Sam and Dean's encounters with Jesse and Cesar and wonder how the brothers would answer the question about “hanging up our spurs.” After all, they watch that very story unfold with these two hunters---and while Sam and Dean still have awhile to go before the end of this fight with Amara, it can't help but have crossed their minds.
