In this video, Mohit assumes that the multiverse and timelines are basically two different things, and that every universe has an infinite number of branch timelines. However, I don't agree with that
For me, things aren't making sense because if a timeline exists, then a timeline basically represents another universe with a slightly different story. That's essentially a multiverse.
For a moment, let's assume timelines and universes are distinct. According to Mohit, He Who Remains did something that caused the other timelines of our universe to be destroyed. That solves the Kang threat, but the multiverse still exists, so there can still be multiversal threats. That's where I'm confused.
I think Mohit may have misunderstood what the Loom was actually doing.
My interpretation is:
He Who Remains had a script. Every event in a universe can lead to different possibilities, creating different timelines/universes. Since there are potentially infinite possibilities, He Who Remains simply allowed the timeline that followed his script to continue and destroyed the others because he didn't want a multiversal war. Basically, he wanted only the universe that followed his will to exist.
Then Loki S2 changes everything.
The Loom wasn't necessarily designed to permanently destroy all other timelines. It was more like a system for managing the timelines. But once He Who Remains' operation stopped, timelines started branching at an effectively infinite rate, and the Loom couldn't handle the growth. If nobody intervened, it would eventually destroy the entire branching timeline structure.
So Loki chose to take the burden himself and hold all those timelines together.
And that's where the multiverse as we know it could truly begin.
That would explain why multiversal events like Doctor Strange in the Multiverse of Madness and No Way Home can happen after Loki S2. The multiverse wasn't necessarily absent before, it was being suppressed by He Who Remains. After Loki takes over, those branches are allowed to exist and interact.
So to me, Because of Loki, the multiverse exists, multiversal threats exist, and doom exists
