Listen This Is Just A Stupid Little Idea I Had XD - Tumblr Posts

So if yall didn’t know, in The Hobbit book, Thranduil had the Dwarves locked up for approximately weeks, and Bilbo was just invisible and wandering in the palace the entire time, vibing miserably.

My headcanon, therefore, is that the Mirkwood Elves now have a local legend about a ghost haunting Thranduil’s palace, never seen but generally thought to be harmless. Thranduil scoffs at the idea, but has been seen glancing around at the dark corners of rooms. Legolas fully believes in it and is known to say hello out loud when he enters an empty room, in case the ghost is nearby.

It’s not until Legolas joins the Fellowship that he figures out that the supposed ghost was actually an invisible Bilbo the whole time. He never tells Thranduil, because he thinks it’s funny to see his regal father unnerved by the idea of a ghost.
