Harry Osborn
- Harry Osborn: Now... lets see who's behind the mask
- [pulls off the mask to reveal Peter]
- Harry Osborn: [stumbles backwards] Peter? No... it can't be.
- Peter Parker: [gets up] Harry, where is she? He's got MJ!
- Harry Osborn: No... all he wanted was the tritium.
- Peter Parker: Tritium? He's making the machine again. When he does, she'll die alone with half of New York, now where is he?
- Harry Osborn: [pause] Peter... you killed my father.
- Peter Parker: There are bigger things happening here than me and you.
- [a troubled Harry holds his unused dagger in his hands, and broods over the revelations revealed to him. A door swings open, and he suddenly hears a cackling laugh...]
- Harry Osborn: Hello?
- [he takes a few steps and then hears a noise]
- Harry Osborn: ...?
- Green Goblin: Son...
- [Harry looks around]
- Green Goblin: [in a mirror] I'm here.
- Harry Osborn: Dad? I thought you were...
- Green Goblin: No. I'm alive in you, Harry. You swore to make Spider-Man pay... now make him pay.
- Harry Osborn: But Pete's my best friend!
- Green Goblin: [serious] And I'm your father. You're weak. You were always weak and you will always be weak until you take control!
- [calmly]
- Green Goblin: Now you know the truth about Peter. Be stong Harry. Avenge me.
- Harry Osborn: No...
- Green Goblin: AVENGE ME!
- Harry Osborn: NO!
- [he hurls the dagger at the mirror, smashing it. Within it, he discovers, lies a secret room. To his shock, he discovers the Goblin mask, shelves of pumpkin bombs, tubes of green elixir, the glider and finally understands it all...]
- Peter Parker: [sees Harry drinking] Hey, you might wanna take it easy there, buddy.
- Harry Osborn: What, it's a party... wouldn't you be drinking if you lost a bundle on some crackpot who you thought was gonna take him with you to fame and fortune? Not to mention your friend the bug.
- Peter Parker: Not tonight Harry.
- Harry Osborn: Every night! Until I find him it's 24/7.
- Harry Osborn: Kill Spider-Man, I'll give you all the tritium you need. On second thought, bring him to me, alive.
- Dr. Otto Octavius: How do I find him?
- Harry Osborn: Peter Parker.
- Dr. Otto Octavius: Parker?
- Harry Osborn: He takes pictures of Spider-Man for the Bugle. Make him tell you where he is.
- Dr. Otto Octavius: Have it ready.
- [Runs down the building]
- Harry Osborn: [shouts] Don't hurt Peter!
- Harry Osborn: Nobel Prize, Otto! We'll see you in Sweden!
- Dr. Otto Octavius: [to Peter] Interesting person, your friend.
- Dr. Otto Octavius: [during the lab demonstration] Precious tritium is what makes this project go. There's only 25 pounds of it on the whole planet. I'd like to thank Harry Osborn and Oscorp Industries for providing it.
- Harry Osborn: Happy to pay the bills, Otto.
