I have been reviewing the Marvel TV programs that are located chronologically after the Snap and these are:
1. Agents of Shield S6 and the end of S7
2. The last chapters of the Runaways S3
3.Helstrom S1
(If there are other programs that are located after the Snap, add it in the answers)
So looking at the 5 year time jump scene in EndGame and what happens on these shows is very contradictory. I mean in Endgame years have passed and you can still see the devastated cities and in the programs it seems that they continued as if nothing had happened, honestly I don't buy it.
Here's my headcanon theory: What if the surviving wizards (including Wong) cast a calming spell immediately after the Snap?
That's why the people on the shows don't seem to care much about what just happened, they are aware that half of life is gone but they are still under the effects of this spell, I mean like the pills that are used in the funerals to calm a person who is emotionally devastated.
As for the duration of this spell, I think it had a time limit of 3 years between 2018 and 2021, after that the effects were lost in the people who began to realize the true consequences of the snap, what they began to collapse would fit perfectly with the 5 year time jump scene from EndGame.
What do you think about this theory?
