Background
Background to the story: The avengers (include Stephen strange, Wong, Loki, Captain marvel, Fury, Maria hill, Pepper, Rhodey, Monica), the guardians, Peter, Shuri, America chavez, Yelena are in the theater.
Everyone are from 2018, three weeks before Thanos. Nick Fury and Maria Hill don't know things that happened after ultron because they aren’t involved with shield anymore and they don't the details of what coulson's team did after shield fell.
The one that brought them is a some sort of spirit (just go with that).
So all of this is after they know what happened in the future. So they know the events of Thanos and the consequences.
They all already watched infinity war, endgame, wandavision, spiderman far from home, TFATWS, Hawkeye, doctor strange in the multiverse of madness.
