I know Spider-Island is happening in the show. But it feels too soon. We haven't seen Green Goblin or Lizard yet.
And given that we're going to have a four episode story about Doctor Octopus, I don't see how they can do that this season.
Thinking about it, Peter probably already knows MJ. And given Marvel's lack of romance on their Disney XD animated series, I can't see a "Face it, Tiger" style introduction.Hence my emphasis on "proper" debut .
