The key moment in the entire mcu. Loki’s decision to let go, to fall through the void, to basically kill himself, shapes the entirety of the marvel universe.
If loki hadn’t had let go he never would have encountered Thanos. He never would have been given the mind stone, or led Thanos to the space stone on earth. The avengers would have never have formed. Even if there had been a different threat, odin would have never used dark magic to send thor to earth unless it was loki he was fighting. There would never have been a nuke sent to New York. Tony would have never gone through the portal. Tony would never have built Ultron. Wanda wouldn’t have joined the avengers. Vision wouldn’t have existed. Loki wouldn’t have been imprisoned so frigga would have lived as no one would tell the kurse where to go. Odin wouldn’t have been weakened and die of grief. Meaning that thanos would have been out matched, and, as the tessaract was originally part of odin’s treasure chest, he would have stopped thanos from getting the space stone. And if thanos didn’t have the space stone, none of the events of infinity war would have happened.
All of this happened because loki. Let. Go.
I wonder if loki ever realised the significant effect he would have on the universe. I doubt it. I think he let go because he believed himself as insignificant. He was a second son. Everytime he strive for greatness he was overshadowed or stopped by his father and brother. Loki thought himself a footnote in the universe, but instead, he was the author.
As in the comics, Loki truly is the god of stories. He’s been shaping the story of the mcu, even without knowing it.
It was loki’s story that led us into this mess, and you can be damn sure it will be loki’s story that gets us out of it…
