May Parker: We need a hero, couragous sacrificing people, setting examples for all of us. Everybody loves a hero, people line up for 'em, cheer for them, scream their names, and years later tell how they stood in the rain for hours just to get a glimpse of the one who told them to HOLD ON a second longer. I believe theres a hero in all of us, that keeps us honest, gives us strength, makes us noble. And finally gets us to die with pride. Even though sometimes we have to be steady and give up the thing we want most, even our dreams.
Harry tells Doc Ock that in order to find Spider-Man he must find Peter first. Doc Ock finds Peter with Mary Jane in the cafe and throws a car through the window straight at them, then later throws Peter against a brick wall. Any normal person would've been killed instantly (or very badly injured), and Doc Ock doesn't yet know that Peter is Spider-Man. Given that Peter is his only lead on Spider-Man, it makes no sense that Doc Ock would try to kill him.
Dr. Curt Connors, Peter's one-armed teacher in the film, is the man who will later become The Lizard, one of Spider-Man's longest running enemies.
