Vermin recalls painful memories of some kind of abuse he endured as a child. It’s the source of all his pain. Harry falls off the deep end and gives into his visions of his father. He puts on the Green Goblin suit and fights Spider-Man. He hits Spidey with some gas that knocks him out and says he wants to suffer in his mind and takes off both their masks.
