Well, I didn't expect that they would have Peter's father still alive (and in prison). That's crazy.
Last week, I said that Osborn collected Peter's DNA so he could do some cloning. It seems like I was right on that.
I didn't expect them to loop back to the first episode, though. Also, they're setting up season 2 to have Venom but I think that this Peter is too young to deal with Venom.
