In The Amazing Spider-Man #121-122 (June-July 1973), while Harry is ill, the Green Goblin throws Gwen Stacy from a tower of the Brooklyn Bridge; either from shock or physical trauma during Spider-Man's rescue attempt, she dies before hitting the water. The Goblin appears to be killed himself in the ensuing battle with Spider-Man. Grieving Gwen's death, Parker withdraws from his social circle, only to find support from Mary Jane, who eventually starts dating him. Harry later discovers the truth about his father and becomes the second Green Goblin. Gwen's death has another unforeseen consequence: one of her professors, Miles Warren, clones Gwen and Peter. Both clones disappear, but Peter's clone returns years later as Ben Reilly. Later still, Mary Jane and Peter break up, as she is not ready for a committed relationship.
