When Mary is at the river, she washes her skirt and we can see how it is soaked in the water. After she shoots the man that is chasing her, Shannon comes to her and when they both are running back to the house it's completely dry.
Struggling to stay alive in a dangerous post-apocalyptic world, Mary still keeps her armpits and bikini line clean shaven.
On hearing a distant shot in the dark, the gang leader immediately cries out, somehow knowing his son has just been killed, and yet he didn't even know he was missing.
While Mary and Shannon are killing the attackers, Adam and Henson are trapped in the basement and angry that their attacker won't come down so they can kill him, they seem unaware that the rifles they are aiming at him can kill from a distance.
Desperately short of ammunition, Adam and Henson waste five bullets killing two unarmed gang members trapped in the basement.
Continually struggling for years to find safe shelter in a post-apocalyptic world, with everyone wearing jackets in clearly cold conditions, under her jacket Mary is only wearing a thin, short, sleeveless sun dress as if she was planning a day at the beach.
