Oh, I know about NYC geography. It should take like 25 min to drive from Elizabeth, NJ, to Manhattan. Hm, that translates to about 7 min of swing time. And maybe about 4 min glide time.
You're forgetting one thing. If it was supposed to be known Spidey arrived much later than Goblin, they would've told us. All this detective work you're putting in isn't necessary, especially for a show like this.
If what you're saying about travel time is important, they would've given us a shot of GG going over the Hudson, and Spider-Man looking at him, then saying something like "Oh boy, I guess I have to use the long way around." It wasn't important, so they showed GG gliding, then next scene, Spider-Man flies through the door.
I definitely noticed Harry and those Goblin boots made him taller than Spidey, I don't know what YOU saw.
The leg injury healing holds no ground IMO. His regenerative abilities does not work that fast.
Thank goodness Harry doesn't have you guys as a jury, a guilty man would've gotten off scott-free.
