The way the Ninja pledge their assistance to Lloyd prior to their attack on Lord Garmadon's base camp references a scene from the film adaptation of The Lord of the Rings: The Fellowship of the Ring, where Aragorn, Legolas, and Gimli offer their sword, bow, and axe (respectively) to aid Frodo in his quest. The episode title is similar to that of the third book in The Lord of the Rings trilogy, Return of the King.
