The fate of this energy is what interest me. Foster will be cured from it for sure but maybe Loki will take possession of it and use it to escape at the end.
She's not an archaeologist, why would she be studying artifacts
? Maybe the elves put the energy there to let it stew for use later like they're going to use it to destroy earth. Though why they would put it in her and not just use it...hmm...my idea is flawed...
