Season 6, post-6x08, diabetic!Dean (Sequel to When You Least Expect It): Soulless!Sam buys Dean the wrong insulin needles and he ends up taking double his dose, causing him to suffer a massive blood-sugar crash during a hunt. Given Sam's recent track record of failing to help his brother when he's in need, will he make it through, or will Sam leave him for dead? *NO Wincest.*
