Loki killed by Sif & Warriors Three
Looking for a fic where in the past Sif and the Warriors Three killed Loki then covered it up. By having a clone of Loki made that obeyed their will. After the Avengers movie the Loki clone was before Odin and the truth was revealed. It is learned that Loki had been reborn and Thor learns that it is Tony. Who has Loki talking to him in his head his entire life. Anything like this fic would be liked thanks
