The cycle Ragnarok works in mysterious ways. When Thor called forth the Asgardians from their mortal shells, Asgard was surprised to find Loki much more boobtacular. Loki claimed it a mysterious twist of fateβ the more things stay the same, the more they change. A new beginning, a new body.
But he was lying. Loki had used the vagaries of reincarnation to usurp Sif's body and keep her locked up in the husk of a dying woman. He used that fact to torment her while he used her face to reshape his reputation. It was, by all accounts, a dick move.
SOME OBSERVATIONS
β I play Loki c. Thor #603, right before he surrenders Sif's body.
β I always use male pronouns to refer to Loki. ICly, characters are free to make their own assumptions.
