3- Green Goblin:
-Norman, behind the scenes, is actually getting stronger and decides to take matters into his own hands. He takes a final dosage of the reformulated serum to make him strong, agile, etc. He also has his technology and all that. Gotta have that.
-Peter and Gwen are really serious now, fully past their flirty fun stage, but still with that same kind of chemistry.
-Peter and Harry have become really good friends, but Harry obviously has issues at home. Peter meets Norman a few times, and later on realizes not only that he's the Goblin, but he's responsible for his parents' deaths.
-MJ also becomes a pretty good friend, but she and Peter are too different for Peter to really feel any sort of real feelings for her (she's a rather hard partier.. is that a word?)
-At the Bugle, Eddie Brock loves his job, loves getting out whatever he can to the people for their benefit. But yet, he's a jerk about it and craves the attention. His father had worked at Oscorp with Peter's father, and feels a sort of bond to Peter but also resents him imposing on his job. Peter sees him more as a creep.
-Bridge. Gwen. Depressing. We all cry. Goblin beaten down, impaled. Doesn't say "Don't tell Harry."
-MJ tries to comfort Peter, but he rejects it, wondering how she could possibly have any idea what he's going through, etc.
-Movie ends pretty depressingly, mostly because it's not the last one.
4- Symbiote & Mysterio:
-Some time has passed, things have died down in Peter's regular life and superhero life. He decides to try to get his mind off of some things by getting more into science again. In doing so, he ends up researching his father's work even more. He sees that his dad and Eddie Brock Sr. had been working on a cure for cancer. Intrigued, he wants to dig deeper.
-Gwen's death has left him scarred, and he takes a break from his duties as Spider-Man, thinking that it would be for the best for everyone involved. And in his thinking of the greater good, he can't help but think that a cure for cancer would be the greatest good he could do.
-Peter sneaks into the now shut down Oscorp to look for as much of his father's work as he can find. He finds his father's planned work, and even a test sample of the cancer cure. He brings it all home (he lives on his own now) to study, then thinks back to the last time he got too involved this way. He pushes it all away, under the bed or in the closet or somewhere like that.
-Quentin Beck, a somewhat crazy special effects artist, has just been fired for his overly dangerous live stunts he's planned. He's also always wanted to direct. He chooses to embark on his own project, starring the one and only Spider-Man. He challenges Spider-Man to a test of skills, throwing whatever he can think of at him (a lot like the Spider-Man 2 video game, lol). Peter, looking for a way to escape his troubles, decides to go along with it.
-Eddie Brock writes a story on this, criticizing Spider-Man for his abandonment of his regular public service and showing up for such a meaningless exhibition. Peter, who's grown to genuinely dislike Eddie at this point, is infuriated, but mostly at himself for being so selfish again after all that's happened.
-Harry and MJ are worried about him, but, afraid to let people get too close, he keeps pushing them away more and more. This exclusion actually pushes the two of them closer to each other, and start dating casually.
-Peter's isolated himself, and though it's what he wants, he's incredibly miserable, alone with just his thoughts.
-Meanwhile, Beck has created an elaborate, over-the-top outfit for himself, so he'll be taken more (less?) seriously. He projects a terrorizing scene onto the city, luring Spider-Man back to him to play his game. Peter, realizing that no one's really in danger and it's all a hologram and then having to struggle to escape, is incredibly annoyed.
-Back at home, Peter brings all of his father's things together to throw them away. The sample is in an unopened high-tech container, so he doesn't even know what it really looks like. Putting everything into the trash, he sees some black gunk on his finger, which he them rubs off on the trash can/ dumpster and walks away. He goes home to take a nap. When he wakes up, his father's stuff is back in his room. Confused, he scratches his head. Some black goop comes from under his fingernail, onto his head, and suddenly the rest, from the container rushes out and onto him. This is painful. He feels like he's being read. He tries to rip it off, and in his struggle he falls out of his large window. He's not wearing webshooters, but out of instict, he shoots a web at the side of the building and it works. It's a black web. He's wearing a black suit (classic black suit?). He feels stronger. He feels carefree, as if his cares have gone into remission. Somehow he finds out all the cool stuff the suit can do and just decides not to question it.
-Myseterio, tired of losing his littel challenges, calls out Spider-Man for one last game. Peter goes, confident, ready to just shut him up. But as he zips through the city he sees the Green Goblin smiling at him on a rooftop, holding Gwen. He rushes over there and as soon as he does, they're gone. He looks around for them, turning the corner only to see a giant lizard. In awe of the sight, He freezes. Electro appears behind him. Peter closes his eyes. When he reopens them, he sees Gwen again. He rushes to her and she doesn't disappear. But then he hears another voice behind him, the voice of Captain Stacy saying "You promised, Peter." And with that, Gwen fades away. Peter can only breathe, cry, and try to think. He kneels, in pain from his tears. But then he hears another voice. "Peter. This is not the man I raised you to be. Son, you have great power. And with great power, there must also come gr-" *BOOM*, a gunshot. He's gone. Peter yells into the night. Then a distant, yet close voice fills his mind. "Enjoying the show, Spider-Man?"
-Peter eventually takes down Mysterio, leaving him broken, clinging for his life. Peter stops only when he sees how far he's gone, almost killing the man with his own hands.
-It's then that he starts to truly realize something's going on with him. After webbing up Mysterio for the police, Peter goes back home to think. He can't think in there. He goes back out, final swing in the black suit, as he comtemplates.
