Robert Downey Jr. is returning to the Marvel Cinematic Universe in the role of Victor von Doom a.k.a. Doctor Doom in Avengers: Doomsday and Secret Wars.

It’s a watershed moment in the continuity, but it turns out Stark's demise actually could’ve happened in a different movie. So, now, I have some questions following this major revelation.
