I really hope one of you may be able to help me out. I can't seem to find this fic and it's driving me crazy! the story I'm looking for has Loki's illusion showing up in Tony's workshop while the real one is imprisoned on Asgard. They get to talking and Loki tries teaching Tony magic (I think it had something to do with sounds). Tony reads up on Asgardian law, trying to free Loki.
