Season 5, 6 and 7 are still in the sacred timeline headcanon
This has been bugging me for years. Nothing in the show really indicates that season 6 onwards is a seperate timeline from the mcu. The idea is that season 5 is a time loop where graviton blowing up the earth stoped thanos from snapping his fingers in infinity war. And when the agents broke the time loop, infinity war happens normally. Just because the show doesn't mention the blip despite seasons 6 and 7 taking place during it, doesn't mean it didn't happen. In fact, there was a cut line in season 7 where they say something along the lines of "the blip sucks, if we gotta focus on the now".
This whole season 5 sent them to a alternate timeline perception is from the behind the scenes disconect between marvel TV and marvel studios. But it has no basis in the show because that is simply not how the season 5 time loop worked. It doesn't make sense for their actions to create a timeline where thanos gets stopped in wakana as a lot of people believe. If season 6 and 7 never happened, then there would be no confusion about the show's place in the sacred timeline, because season 5 leads up to infinity war pretty neatly. You just have to assume none of the aos cast got snapped.
Sorry. I just got the get that off my chest. The only thing that could actually contradict the sacred timeline, is sheild being a active organization by the end of season 7, during the blip, complete with a rebuilt HQ and helicarier. But.... Even with that, you can just assume that sheild is a much smaller organization then before, and holds no relevancy in the current shows and movies. That can simply be written as them being off screen and out of the public eye, secret from most heroes.
