As Danny is in his pajamas lying on his bed (at around 32 mins) he has no abrasion over his left eyebrow, but when a gunshot awakens him (at 14:02 and throughout the rest of that scene) he does have abrasions over his left eyebrow. Similarly, when Danny and Wayne hide behind a tree as the Sweeney brothers ride by on their bikes, Danny has no abrasions (at around 7 mins), but after being chased by Andy Sweeney and falling, Danny does have the abrasions over his left eyebrow (at around 29 mins), but we know they are from his fall.
