At the end of Loki I got the impression that timelines no longer had to be pruned and that every timeline can exist. But in this movie it seems the TVA is still talking about “The Sacred Timeline”. Does this mean that Loki is only holding together the sacred timeline and just adjacent branches?
I will always consider Deadpool to be mildly canon unless verified by other sources.
However, you could infer that timelines can exist. They're no longer cumbersome to the multiverse. But if they're unstable, they might just die on their own (over thousands of years).
Timelines dying on their own always made sense. I was just under the impression that the whole point of season 2 was that it’s wrong that there is a “sacred timeline” dictating what timelines are important. The Loom restricted how many timelines could exist, and that Loki now holds all of them. Unless “sacred timeline” is still being used to mean “every timeline where Kang doesn’t become Kang”, which would also mean we’re kind of right back where we started at the beginning of s1 Loki, plus some additional branches? And instead of the loom it’s Loki holding it together?
My only thought is that Marvel was originally going to down the path of letting Kangs exist without the sacred timeline, but since they did away with Majors, they brought back the sacred timeline as a way to retcon the antman after credits scene.
I think it's important to note that Paradox was explicitly acting outside of the TVA's authorization. That machine seemed to be a last resort mechanism that he was using liberally.
Aside from that, the sacred timeline still exists. It would have made sense to call it Prime or something. But it already has the branding.
I guess that could be an argument that makes sense, not rebranding or needing the audience to remember Earth 616, since Sacred Timeline is an easier name to remember.
