did harry osborn know his father was the green goblin
Harry is dumped by Mary Jane Watson due to being fed up with his self-destructive lifestyle. Disconsolate, Harry turns to drugs and suffers an amphetamine overdose. He survives, but this tragedy, compounded by imminent bankruptcy, drives his father Norman Osborn over the edge. The elder Osborn kidnaps Gwen as bait for Spider-Man, and then throws her off the George Washington Bridge (or Brooklyn Bridge). In a vicious battle with Spider-Man, the Green Goblin accidentally impales himself on his own goblin glider. Harry Osborn secretly witnesses this. Wanting to protect his father's identity, he strips Norman Osborn's body of the Green Goblin costume. Blaming Spider-Man for his father's ``murder'', Harry, angry and mentally unbalanced, swears vengeance. Having inherited his father's company, Harry manages to get the business back in shape. One day, to his shock, he finds a Spider-Man costume in Peter Parker's apartment and realizes that his best friend is the man he blames for his father's death. Using his father's old equipment, Harry confronts Peter as the second Green Goblin.
