Doctor Strange in the Multiverse of Madness offers a unique opportunity for a final send-off for Iron Man — and a unique opportunity for character growth. In Avengers: Infinity War, Doctor Strange uses the Time Stone to predict the exact chain of events, including his own temporary death, that will lead to ultimate victory against Thanos. Naturally, he does not tell Iron Man that his death is a necessary step along the path to victory. When the time comes, Iron Man is willing to make that sacrifice at just a nod from Strange, and the faith in Strange's implication that it was the exact chain of events the sorcerer had foreseen for victory to take place.
All of this, including Strange's direct involvement in Iron Man's death, will be something that he has to deal with in Multiverse of Madness. While survivor's guilt has been explored before, Doctor Strange didn't directly fight Thanos in Infinity War and knew from the outset that his actions would lead to Iron Man dying after starting a family. To have this kind of knowledge and to make that choice for Iron Man would impact Strange emotionally, especially if the explorations into the multiverse show him what the world would be like had he chosen otherwise. Multiverse of Madness, therefore, gives one of the most concrete opportunities for an MCU hero to have certain knowledge of the consequences of their actions.
