What was up with Ned's character arc? (spoilers)
I'm aware that he was the Hobgoblin in the comics, though I never expected him to become the goblin in the movies because, well, the obvious reason that he's a fat comic relief character (though to the actor's credit he lost a lot of weight, but he was still chubby). And then the line about Tobey and Andrew's best friend Harry becoming the Green Goblin seemed to me like some kind of foreshadowing. But not only did they give Ned some kind of magic background with his family instead, they then ended up erasing all his memories of Peter anyway, so no magic and no Hobgoblin despite the foreshadowing.
I tried looking up online to see if this version of Ned was also based on some other character, like a student of Strange or something, but I couldn't find anything. In the end, the writers just took complete creative freedom and came up with a way for him to stay relevant to the plot without anything coming from it. I just thought that was kind weird.
