Kíli is stabbed to death by Bolg, and a heartbroken Tauriel returns the talisman to his lifeless hand. Tauriel stayed there, mourning over his death before Thranduil came upon the pair.
In The Hobbit, both Fili and Kili die. As written by Tolkien: ''Of the twelve companions of Thorin, ten remained. Fili and Kili had fallen defending him with shield and body, for he was their mother's elder brother...'' In addition to Fili and Kili, Thorin also dies in the book.
She successfully finds Kíli and the two battle against Bolg together. She is overpowered and almost killed by Bolg, but Kíli sacrifices himself to save her. Tauriel mourns over Kíli's body and kisses his lips, thus showing her fondness for him.
Fili and Kili are not half-elf. They are the maternal nephews of Thorin Oakenshield, the dwarf, and are themselves dwarves of the line of Durin, the Longbeards.
Sometime after the Battle of the Five Armies, Kili wakes up in the Caribbean with Tauriel mysteriously appearing with him. After several years of living together, the two finally marry. The duo is later shanghaied into service aboard Queen Anne's Revenge under the fierce command of Captain Blackbeard.
Kili is based on the character of the same name from The Hobbit by J. R. R. Tolkien. He is also from the film version of The Hobbit by Peter Jackson. Kili has had one love interest: Tauriel. After he is resurrected, they marry and have a son named after his late brother, Fili.
It is later mentioned that Tauriel is a talented warrior and was therefore made leader of the Mirkwood border guards. Legolas, the son of Mirkwood's Elven king Thranduil, is indicated to be attracted to her, but as she is a lowly Silvan Elf, she does not believe herself worthy of him.
Legolas does not marry or have any children, based on the appendix of The Lord of the Rings. Regardless of who his mother was, Legolas is the last of his line. When he sails into the West at the beginning of the Fourth Age, he leaves no family members behind.
Tauriel was an Elf of the Woodland Realm and the head of the Silvan Guard. Thranduil adopted her when her parents were slaughtered by Orcs and Legolas is like a brother to her.
In Lake-town, Kíli becomes gravely ill from the poisoned arrow and Thorin orders him left behind. Óin stays behind to tend him, and, when Fíli fails to change Thorin's mind, he defies his uncle in order to stay behind as well to be with his brother.
Their deaths and Thorin's did not end Durin's line, although did end the branch which had Thror, Thrain, and Thorin Oakenshield. Thorin's cousin, Dain Ironfoot, became King after Thorin's death. Dain's son, Thorin Stonehelm, became King after Dain died in the Battle of Dale. The line continued on after that.
Why did Thorin go crazy? Thorin fell victim to the sickness of greed. Dwarves are known for being greedy and proud, and when he realized the treasure of Erebor was his, including the Arkenstone, he became ill with Dragon Sickness. He began to value his wealth more than his friends, family, and own safety.
After the death of Thorin in the Battle of Five Armies, Dain becomes King under the Mountain. He redeems the Arkenstone from Bard with a fourteenth of the treasure, which is used to re-establish Dale. Over the next three years, Bard rebuilds the city of Dale and becomes its ruler. The city begins to prosper again.
It is believed that after Kili dies, Tauriel becomes a lone rider and never loves again, she was so broken by the experience of losing him. Their love was real, and it was as strong as any other Middle Earth romance story. But this romance doesn't appear in the original book, so where did it come from?
Tauriel truly threw a wrench in Legolas' life when he fell in love with her. She was brave, fierce, and a protective leader of the guard. He was meant to be the dutiful son of King Thranduil, but in loving her, he became a stubborn, masterful archer instead. He loved exploration and adventure over his duties.
Legolas and Gimli's relationship is strong in The Lord of the Rings, even though it wasn't explicitly romantic in Tolkien's source material. The members of the Fellowship in The Lord of the Rings forge an unbreakable bond while on their mission to destroy the One Ring.
However, a specific scene in The Lord of the Rings has led fans to theorize that Frodo and Legolas didn't talk, not because of time, but because the hobbit didn't know Legolas' name (and was too embarrassed to ask).
The actor is suffering from Legolas Syndrome — where you accidentally get cast into a role that suits you far more than your real-life looks, leaving you with a tricky predicament after the wrap party. Do you A) nick all the costumes and stay in character the rest of your working life, or B)
Spoiler! Kili gets shot by a Morgul-shaft in DOS, and Frodo gets stabbed by a Morgul-blade in FOTR. Yet it appears that Frodo's injury is much more severe than Kili's...
Kíli is stabbed to death by Bolg, and a heartbroken Tauriel returns the talisman to his lifeless hand. Tauriel stayed there, mourning over his death before Thranduil came upon the pair. It was then that Tauriel declared her love for the Dwarf, before leaving his side.
Thorin was entombed beneath the Lonely Mountain, and presumably3 Fíli and Kíli were also buried there. Thorin's nephews were the only remaining heirs of his line (indeed, if Kíli had survived the battle, with Thorin and Fíli slain, he would have become King under the Mountain).
