Warning: Very dark Gabriel is away on business for the day when Castiel asks you to check out some suspicious demon activity. Things don't go according to plan, however.
As the younger son of the King of Mirkwood you find yourself for the most part completely devoid of friends. This changes the day 13 dwarves are imprisoned and you run into an odd hobbit who has been travelling with them. And that might be a little bit of a crush you have on him there. Let's just hope your father does...
You run into a handsome but cold elf on your way home one evening - quite literally. And you decide to make his day by accompanying him to his work place. Then you just ... continue to do so.
