Two years ago Bruce Banner died, and with him, the Incredible Hulk. And then suddenly, that wasn’t the case. Bruce Banner came back, and brought the Hulk with him – but death changes a person, and that remains the case whether you’re a man or a gamma-irradiated monster.
Bruce Banner has a cold. Well, the flu, really. He gave it to himself, just to make sure he really can’t turn into the Hulk anymore. His snot is yellow, not green.
