In Loki Season 2, the former God of Mischief has a much bigger task at hand than in the first season. Loki has fought tooth and nail, trying to figure out how to save the Time Variance Authority (TVA) and the fraying Sacred Timeline. It turns out, Sylvie murdering He Who Remains created macabre ripple effects, with the Temporal Loom fraying and the Multiverse being endangered.
