Just for giggles, pause the screen when Sam first gets the case in Wisconsin. You can read the e-mails. Eating contests, Biggerson’s reward program, who owes for gas in the car, searching for car parts for Baby, Dean’s commentary on cases. A few good memories I saw on screen that I missed at the first watch. These details are priceless for Supernatural fans. So even more to look for on second watch. Take a look. It is a memorable episode with many echos. I still think the writing is clever for a new writer to be so invested in his research as to use smallest details to make characters feel real, but I still wonder at the whole legacy speech. And yes, the Winchesters are facing an existential battle against BMOL. People are crazy….monsters play by the rules.
