Provided Lady Loki is Enchantress, viewers may very well be witnessing both the end and beginning of an overarching plot devised by the Loki that we’ve been following so far.
I mean, we already know Loki’s central iteration isn’t a fan of the idea that everything is pre-determined under the Time Keepers, and he doesn’t have all of the emotional growth that Prime Loki had before his death, so is it really so crazy to believe he’d put a lot of effort into ridding himself of all that?
We’ve already been told by Mobius that time works a little differently in the TVA, so it wouldn’t be crazy to think that Loki could very well be on a collision course with himself – literally himself, and not just another variant – that will ultimately lead to his escape, as well as potentially the most massive catastrophe in the existence of time.
