It's official. MCU and Robert Downey Jr. have worked out their differences and ironed out the details for Iron Man to be back in the Marvel Universe. And we will be seeing Tony Stark's refined mug in the third Spider-Man movie starring Tom Holland in a cameo. Our questions being, what sort of a cameo will it be? Will it be more of a memory or hallucination on Spider-Man's part? Or will Tony Stark now exist as AI, considering the man himself snapped his fingers into oblivion.
