Has to be a Wizard of Oz scenario. But who's the man/woman/other behind the curtain?
At this point, we don't even know whether there are real Time-Keepers, most of the premise could be a set-up. We know the TVA exists and has the power it does, but we don't know that it's really being used to preserve a Sacred Timeline to prevent a multiversal war, let alone that there's Time-Keepers in charge of it.
(I still think it's Lokis all the way down).
