Here's my take on the loki finale and why Mobius is the only one of the gang who didn't seem to have a conclusive, 'hopeful' ending.
Can't predict what the writers are thinking but the way I understand it is it's a hint that there's no version of reality where Loki is not there with him that will ever leave him fulfilled.
"Most purpose is more burden than glory," he said.
Others are shown finally having the choice to pursue their own "glory"/hope/ happiness. B-15 finds her purpose to lead and protect something she believes in, O.B. gets to live out his science fiction dream, writing a book of a place he now knows to be true and care about.
The end scene with Mobius and Sylvie is fascinating, for instance, because it shows the contrast between them both. Sylvie is different, she's reconstructed her own reality, found her own happines, lived a whole new life in the timeline without Loki or anyone.
But Mobius is the realist out of them all.
Mobius said before that he'd rather not know about his life before as it's easier not to, that the TVA is his whole life, that that's where he belongs. When the TVA changed, he finally left, but now he's there in front of the life he's supposed to have but he's in no hurry to go back, content to just "let the time pass."
I think he knows no matter which purpose he chose, whether at the TVA or getting his memory reinstalled back to him for a life on the timeline, there will always be a 'burden', something left lurking behind.
Maybe he realises he doesn't have a place 'he belongs to' anymore.
Perhaps it also dawns on him then, that it's never about the how (the TVA is changed now, no more prunings, no more sacred timeline, he would've done something he'd morally believe in if he stayed),
or the what (the jet skis, his garden, even his family, it could never be the same. It's incomplete, with all the burden of eons of memories behind him, and the lost of someone who made it possible)
or even the why (he's driven by 'the bigger picture', it's his one saving grace, the one thing he holds on to. He spent eons doing the same thing over and over, protecting the sacred timeline and what he believes to be true, when that turned out to be a bust, he turned his life upside down to protect his new purpose, the multiverse, but all of it is still to waste, they couldn't do it still, not without sacrificing-)
In the end, that wasn't what it's all about. The reason this whole madness started was because of one simple act of his, an insignificant character, to save someone, to be willing to take the leap in trusting one that everyone always dooms to fail. To tell that person, who never had anyone believe in him before, that they could "be anyone they want to be, even someone good."
It was never about the universe. Loki was right. It was never about the how, the what, or the why.
so…the god who’s biggest fear is “i don’t want to be alone” and who “never wanted a throne” has now resigned themself to a lifetime in solitude. on a throne. making an ultimate sacrifice so that everyone else can live.
don’t fucking talk to me. mobius better go save your bf!!
like I’m fairly certain that Disney won’t let lokius become canon, which yknow, sucks, but I was kind of expecting that. As long as they stay together in some way shape or form and sylkie doesn’t get together last minute I’ll be content :,)
