it might have been, and that's probably the most likely, but we also don't yet know who is replacing Heimdall as the Bifrost guardian, since time shenanigans are involved, it might have also been referring to his replacement. As his sister, I think Sif would be a strong contender.
Raye, you need to draw that picture now! Now I say!

As for his appearance in the prologue, what if the curse did create a double, a Loki who is aware of the curse and who jumps around different points of Marvel history to have a story happen? And then once they're done, they're integrated back to normal Loki with him gaining the double's memories as if they happened to him?
