Consumed with Loki/Sigyn feels.
What if, in Marvel movie!verse, Sigyn knew she was the only one who could truly stand between Loki and the rest of the realms? What if she knew she could bind him without destroying herself, but what is INSIDE him… What if that required a sacrifice? A truly great one?
In my head canon Sigyn is still Incantation Fetter. She has a gift for binding the powers of others. But the greater the binding, the more she is required to give - not just her time, energy, and strength, but sometimes physical pieces of herself. And to bind Loki (and whoever is working with/through him), requires more than a piece. And one day, on the verge of winning what would be a decisive battle, Sigyn comes to Loki, Sigyn Incantation Fetter and Victory-bringer - and he KNOWS. Because my Sigyn comes from a conquered people, and she HATES it. Hates seeing anyone being forced to yield to another.
So when Sigyn comes to him, on that battlefield, Loki’s ego may allow him to believe for a moment that she has come to join him, has come to throw her powers behind him and rule beside him. But the knife in her hand cuts in more than one way, and he’d know before she acted what her true purpose was. Because I think she’d be willing to die to preserve the freedom of the realms. And he’d know that. And the only reason he’ll get to keep her forever despite all their differences is because it’s her life that’s binding him, turning him into an empty vessel for the power he used to be able to command.
Are any of you now filled with Loki/Sigyn feels?
