I am not quite sold that Sylvie is Enchantress and not a Loki variant. I think there is some wiggle room there....
Key items I got out of this...
1) TVA is not what we thought, they were not created solely for this role but are variants themselves and don't know it - the whole mind fog thing makes me think this leads to Kang or Time Keepers being the main bad guy here, or misuse of power kind of thing
2) Loki has some power, and it seems to be different than before. I don't know if he is expanding his power or if he slipped some infinity stones in his pocket. But the whole raising the building thing smacks of Time stone.....
3) I also don't think the "Loki's" are really trapped, my guess is the time pad he showed destroyed was illusion, and he still has the active pad.
Its clear here, the main drive will be to break up what the TVA was or did, and free up multiple universes which will lead to Dr. Strange and Spiderman No way home and Ant and Wasp Quantummania
