In his speech at the end of Loki Season 1 He Who Remains explains that he:
lived on earth in the 31st century [and] discovered that there were universes stack on top of each other.
And that he then wiped out all other variants of himself shortly thereafter.
However in Season 2, the main characters search for a variant of He Who Remains and find it in Victor Timely a man who lives in 1893. We even see him before that as a young boy, also living in that time era. The show then goes out of its way to confirm that Victor is indeed a variant of He Who Remains, not just because he looks similar (and is played by the same actor), but because the TVA computer systems recognize his DNA as being that of He Who Remains.
But what I don't understand is, how is it possible for Victor to be a variant of He Who Remains if he lives in the 19th century, while WHR lived in the 31st? Online I could find a lot of information about Timely's comic counterpart who has a different backstory. But does the show ever explain how Timely is a variant that lives in the past? Aren't variant's supposed to be born at the same time as their counterparts?
Timely also lives on the sacred timeline, which is another oddity, as there is only supposed to be a single version of every person on each timeline and the one for the sacred timeline is clearly He Who Remains. I know that HWR has somehow set up the whole Victor Timely thing, giving instructions to Ms. Minutes and Renslayer about it, but how did Victor end up in the 19th century? Was he born there? Did he Time Travel as a child? Did He Who Remains send him there?
