Is Russell's Story an allusion to Little Red Riding Hood?
Think about--Russell's name means "red", his backpack is red, and his text during the camp scene is red. He's a young and relatively innocent person traveling to his grandmother's house (note how he mentions he's carrying food in his pack--like how Red Riding Hood had food in her basket). He's stopped on his way through the woods by a scruffy creep who agrees to take him to his grandmother's house, but... clearly has other plans in store.
Obviously it's a pretty loose adaptation and mostly a deconstruction, but I feel like there's definitely some kind of influence from the story there.
