what are the signs that summer session is over and the fall is approaching

Finny's Fall from the Suicide Tree: Finny's fall is a fall from innocence. It represents evil being unleashed. The idyllic summer session comes to a close, ushering in hardness and cold. Taking the concept of the fall to the next level, Devon during the summer session can be considered Edenic; Gene is the serpent, and Finny the forbidden fruit, plucked from the tree. The winter session at Devon, therefore, becomes the harsh, cruel world.
