First, a quick refresher: as established in the “Loki” season 1 finale, “For All Time. Always,” the figure referred to as He Who Remains knows everything (up until a point, at least). While chilling at the Citadel at the End of Time, He Who Remains has reached a point of such supreme understanding that he literally hands Loki and Sylvie a script of everything they’re about to say. And the reason He Who Remains knows everything is because he kind of has to, at least in his opinion. He’s keeping a potential multiverse at bay because, when the multiverse did exist, most of the various universes went to war with one another — and from what he says, these wars were primarily waged between different versions of him. That’s why He Who Remains is called He Who Remains — he wiped out all the other versions of himself, and their corresponded universes, to keep the peace.
All of which is to say that He Who Remains is … well, kind of a weird guy. He’s been alone, literally watching time tick by, keeping the seconds in order, and that has made him a little stir-crazy, to say the least. And to get a sense of how such a person might behave, Majors looked to other brilliant but offbeat characters from films in the past, to influence his characterization of this Nathaniel Richards variant.
“Some cultural pop references were, of course, ‘The Wizard Of Oz,’ ‘Sunset Boulevard,’ ‘Citizen Kane,’ ‘Willy Wonka & The Chocolate Factory,'” Majors revealed at the end of the “Loki” episode of the Disney+ documentary series “Assembled” (via Empire Online).
However, don’t expect future variants of this character to behave the same way.
