I've finally watched the final episode.
So basically:
1- Kang "cut" the Sacred Timeline (the MCU) out of the Multiverse (how? Seems impossible), so that other universes could not invade the MCU. Okay. Interdimensional travel to the MCU is not possible, so interdimensional counterparts cannot jump into the MCU. That's right.
2- Time Branches (see ENDGAME) and Alternate Universes are two different concepts. Totally.
STILL, why did Kang steal people from Multiverse in order to create the TVA??? Couldn't he use normal humans from the MCU? That would be much more easy.
ALSO:
Those alternate universes still exist.
All of them.
The Sylvie Universe, the Alligator Loki Universe, the Classic Comic Book Loki Universe and so on and on...............
TVA is supposed to just get rid of potential time branches. But what branches??????????????????????? They were travelling to other universes. Always.
Why the TVA doesn't know or realize or discover that they are stealing people from other universes, not "time branches"?
Great premise, but that's not what is shown on-screen. TVA agents constantly steal people from other universes, NOT "time branches". The agents call them "Time Variants", all of them, but they are not "Time Variants", they are "Interdimensional Counterparts".The Time Variance Authority (TVA) is a bureaucratic organization created by He Who Remains that is tasked with preserving the "Sacred Timeline" and preventing the creation of branching timelines.
According to TVA propaganda, countless timelines battled one another for dominance across the Multiverse in a cataclysmic war that lasted for eons and nearly resulted in the absolute destruction of existence. To prevent this, the Time-Keepers brought peace and order to the Multiverse by arranging the timelines into a single "Sacred Timeline". In order to preserve the timeline's proper flow, the Time-Keepers then created the Time Variance Authority to police the Multiverse from Variants who create nexus events by stepping off of the path that the Time-Keepers created. If nexus events are left unchecked, the timeline could branch off and lead to another multiversal war.
(EXCEPT 2012 LOKI, of course)
And the TVA agents do NOT know that. How can you perform a task and not realize what you're doing? That's impossible.
TVA agents believe that alternate universes do NOT exist anymore, but they steal people from other universes, not time branches.
They just know that there's a single timeline guarded by the Time-Keepers, but they steal people from other universes... without knowing it???!!!!!????
Massive plotholes. Bad writing.
