Eighth grade Sam wrote a paper about his family killing a werewolf the previous summer. Dean told the same story to Gordon in season two's Bloodlust (2006).
This episode is dedicated to the memory of Christopher F. Lima (rigging electrician) and Tim Loock (online editor)
At San Diego Comic Con 2015, when asked if the Winchester brothers would defeat their new enemy, Jared Padalecki (Sam) replied "Yeah, because we're not the LOSEchesters," and in this episode, the bully who terrorized Sam and his friend Barry taunts Sam by saying "Come on LOSEchester!"
The exterior of Sam and Dean's old high school is the same exterior used to shoot the pilot episode of The Vampire Diaries (2009), another show on the CW. Candice king who plays Amanda on this episode also played Caroline on the vampire diaries.
