So the new Hobgoblin has grey skin. Norman's new baby has the combined blood of the Goblin and Menace formulas. They're not going to hyper-age the baby... are they!?
Or Harry who was stealing two viles of Gobby/Menace formula, I suspect to trade for the baby. Maybe they'll brake in his hands during a fight between Spidey and Ock and Harry'll become the new Hobby? Blaiming Spidey, blah, blah, blah. I'm not sure I'd like it but it's make for an epic fight when Norman comes back.
Of course with Norman being gone, Kingsly could fill the void for an evil millionaire villain for a while.
Please don't screw this one up, Dan!
