The Variant’s headgear is interesting; one of the horns is broken. So she’s a Loki but broken or different. Distinctly different; that much was already clear.

“Don’t call me Loki! Don’t call me Variant!” She’s Sylvie. That will cut down on the confusion. She and Loki are evenly matched, but far more different from other Lokis than I think we’ve seen in the comics… She’s far more direct and much more of an anarchist than Loki who, ultimately is a megalomaniac.
