Tauriel
After getting weapons and supplies at Laketown, the dwarves leave for the Lonely Mountain, but leave Kíli behind because of his injury, and Fili, Bofur and Oin stay behind to be with him. By the time Tauriel and Legolas reach Laketown, the dwarves are being attacked by orcs. They defeat the invaders, and Tauriel uses her knowledge of herbs to heal Kíli's wound, saving his life once again, after which they admit that they have developed a bond with one another.
