Frozen AU based on the theory that the trolls made Hans evil (and that he was actually good and genuinely in love with Anna at the start, and all he wanted was to be loved having come from a crowded family where his brothers bullied him or he was ignored), from Han's perspective.
Starts with a nightmare (some what similar to the visions/prophecies that the Witches show/reveal to Macbeth) which suggests the possibility of him becoming King of Arendale, then a small lie and so on and so on whilst Hans internally struggles against the evil planted in him, trying to focus on his love for Anna (with the evil winning out in the end). Discuss how his horse suddenly no longer trusts him etc. (Animals sensing evil, that sort of thing) - tackling the fact that his horse isn't seen in the movie later on.
