Fans of Loki were left in shock when the fourth episode ended with the screen awash in white light signaling the end of the Time Variance Authority. When "Science/Fiction" opened, Loki found himself time-slipping in the TVA again, which is supposed to be impossible. The fifth episode ended with everything seemingly destroyed. While this is excellent dramatic escalation of the stakes in Loki Season 2, it also may suggest He Who Remains didn't actually create the TVA. Eagle-eyed fans who watched the Loki Season 2 trailers knew that more time-slipping awaited the God of Mischief.
