Bilbo and Company are forced to engage in a war against an array of combatants and keep the Lonely Mountain from falling into the hands of a rising darkness.

[From trailer]
Bilbo Baggins: One day I'll remember. Remember everything that happened: the good, the bad, those who survived... and those that did not.
Thorin Oakenshield: [last words]
Thorin Oakenshield: [to Bilbo] Farewell, Master Burglar. Go back to your books... and your armchair... plant your trees, watch them grow. If more people... valued home above gold... this world would be a merrier... place...
Bilbo Baggins: No! No, no, no! No! Thorin! Thorin... don't you dare!
[cradles Thorin, who has already died]
Bilbo Baggins: Thorin... hold on. Hold on. Look. The Eagles. The Eagles. The Eagles are here. Thorin!
[realizing Thorin's dead]
Bilbo Baggins: The Ea -
[breaks down and begins to weep]
Tauriel: [weeps for Kili] If this is love, I don't want it. Take it away, please! Why does it hurt so much?
Thranduil: [sadly] Because it was real.
[From trailer]
Thorin Oakenshield: [to his company] Will you follow me, one last time?
[From trailer]
Bard: Will you have peace, or war?
Thorin Oakenshield: I will have war!
Legolas: I can not go back.
Thranduil: Where will you go?
Legolas: I do not know.
[pause]
Thranduil: Go to the North. Meet with the Dunedain. There is a young Ranger among them. His father, Arathorn, was a good man. His son may grow to be a great one.
Legolas: What is his name?
Thranduil: He is known in the wild as Strider. His true name, you must discover for yourself.
Thranduil: If I am not mistaken, this is the Halfing who stole the keys to my dungeon right from under the nose of my guards.
Bilbo Baggins: Yesh. Sorry about that.
[Bilbo starts off home, speaking only to Balin]
Bilbo Baggins: Could you tell the others I say goodbye?
Balin: Tell them yourself.
[Bilbo sees that the Company has come to see him off]
Bilbo Baggins: If you ever pass through Bag End, tea is at four. You are welcome ANY time. Don't bother knocking!
[From trailer]
Saruman: Leave Sauron to me!
Kili: [from trailer] I will not hide, while others fight our battles for us!
Gandalf: You'll never make it!
Bilbo Baggins: Why not?
Gandalf: Because they will see you coming, and kill you!
Bilbo Baggins: No, they won't. They won't see me.
Gandalf: It's out of the question! I won't allow it!
Bilbo Baggins: I'm not asking you to allow it, Gandalf.
[goes off]
Thranduil: Your mother loved you Legolas, more than anything. More than life itself.
[last lines]
[Bilbo hears a knocking at his door]
Old Bilbo: No, thank you! We don't want any more visitors, well-wishers, or distant relations!
Gandalf: What about very old friends?
[a pleased Bilbo goes to greet Gandalf]
[From trailer]
Thranduil: [to Gandalf] You started this... you will forgive me if I finish it!
Thorin Oakenshield: I am so sorry... that I have lead you to such peril...
[coughs]
Bilbo Baggins: No! I am glad to have shared in your perils, Thorin. Each and every one of them. It is far more than any Baggins deserves!
Gandalf: [to army] You have but one question to answer: How shall this day end?
Dwalin: [From trailer] Bilbo was right. You cannot see what you have become.
Thorin Oakenshield: [Last words] Farewell, Master Burglar. Go back to your books... and your armchair... plant your trees, watch them grow. If more people... valued home above gold... this world would be a merrier... place...
Dwalin: You sit here, in these vast halls, with a crown upon your head and yet you are lesser now than you have ever been.
Thorin Oakenshield: Do not speak to me as if I were some lowly dwarf...
[weeping]
Thorin Oakenshield: as if I were still Thorin Oakenshield.
[pulls out his sword in anger]
Thorin Oakenshield: I AM YOUR KING!
Dwalin: You were always my king. You used to know that once. But you cannot see what you have become.
Thorin Oakenshield: Get out before I kill you.
Galadriel: [banishes Sauron] You have no power here, servant of Morgoth! You are nameless, faceless, formless. Go back to the void from whence you came!
Gandalf: You are a very fine fellow, Mr Baggins, and I am very fond of you. But you are really just a little fellow, in a wide world.
Thorin Oakenshield: [From trailer] Everything I did, I did for them.
Elrond: [to Sauron] You should have stayed dead.
[the White Council appears to aid Gandalf]
Saruman: [to Galadriel] Are you in need of assistance, my lady?
Legolas: [at Gundabad] My mother died here. There is no grave nor memory. My father never speaks of her.
Bilbo Baggins: [From trailer] You've won the Mountain. Is that not enough?
Thranduil: [From trailer] I came to reclaim something of mine.
Bilbo Baggins: [From trailer] When faced with death, what can anyone do?
Gandalf: My lord! Dispatch this force to Ravenhill, the Dwarves are about to be overrun! Thorin must be warned!
Thranduil: By all means, warn him. I have spent enough Elvish blood in defense of this accursed land. No more!
[leaves]
Gandalf: [desperate] Thranduil!
Legolas: [sees a flock of giant bats] These bats are bred for one purpose... for war!
[Thorin attempts to throw Bilbo from Erebor's roughly rebuild ramparts]
Gandalf: If you don't like my burglar, then please, don't damage him! Return him to me!
Bilbo Baggins: You are changed, Thorin! The Dwarf I met in BagEnd would never have gone back on his word! Would never have doubted the loyalty of his kin!
Gandalf: [From trailer] This was the last move in a master plan. A plan long in the making.
Bard: [to Thorin] You brought upon them only ruin and death.
Gandalf: It is Dain, Lord of the Iron Hills. He's Thorin's cousin.
Bilbo Baggins: [jogging to keep up with Gandalf] Are they alike?
Gandalf: [pauses] I have always found Thorin to be the more reasonable of the two.
Gandalf: Dragon sickness is a malady that affects all of us.
[looks at Bilbo]
Gandalf: Well, almost all of us.
Bilbo Baggins: [From trailer] Thorin. You gave a promise.
Tauriel: [to Thanduil] There is no love in your heart!
Smaug: Is that your child? You cannot save him from the fire! He will BURN!
Dain: Good morning. How are we all? I have a wee proposition, if you don't mind giving me a few moments of your time. Would you consider... JUST SODDING OFF! All ye, right now!
Bard: [to Thranduil after failing to negotiate with Thorin] He will give us nothing.
Thranduil: Such a pity. Still, you tried.
Bard: I do not understand. Why would he risk open war upon his kingdom?
Thranduil: [unsheathes his sword] It is fruitless to reason with a dwarf. They only understand one thing.
Thorin Oakenshield: [Staring at the space on the throne where the Arkenstone would be] It is here in these halls.
Dwalin: We have searched and searched everywhere.
Balin: We all want to see the Arkenstone returned.
Thorin Oakenshield: [seething] And yet it's still not found!
Balin: Do you doubt the loyalty of any of us? The Arkenstone is the birthright of our people.
Thorin Oakenshield: It is the King's Jewel. AM I NOT THE KING? Know this. If anyone should find the Arkenstone and withhold it from me, I will be avenged.
Thorin Oakenshield: [whispers like Smaug] I will not part with a single coin! Not one piece!
Thorin Oakenshield: [to Bilbo] I was blind, but now I begin to see... the Arkenstone! One of them has taken it from me...
[points at the Dwarves]
Thorin Oakenshield: One of them is false.
Dain: [when he sees another army approaching] Oh, COME ON!
[seeing the destroyed Laketown]
Balin: Poor souls.
[Bilbo, sitting alone, reaches into his pocket]
Thorin Oakenshield: What is that in your hand?
Bilbo Baggins: [startled] It-it's nothing.
Thorin Oakenshield: Show me!
[Bilbo opens his hand, revealing an acorn]
Bilbo Baggins: I picked it up in Beorn's garden.
Thorin Oakenshield: You've carried it all this way?
Bilbo Baggins: I'm going to plant it in my garden, in Bag End.
Thorin Oakenshield: It's a poor prize to take back to the Shire.
Bilbo Baggins: One day it'll grow. And every time I look at it, I'll remember. Remember everything that happened: the good, the bad... and how lucky I am that I made it home.
Tauriel: [Thranduil arrives at the top of Ravenhill to find Tauriel crying over Kili's body] They want to bury him.
Thranduil: Yes.
Tauriel: If this is love, I do not want it. Take it away, please. Why does it hurt so much?
Thranduil: Because it was real.
Tauriel: [Tauriel cradles Kili's hand in hers and leans down to kiss him]
[the night before the Elves are set to attack Erebor, Bilbo brings the Arkenstone to Thranduil's tent]
Thranduil: The King's Jewel...
Bard: And worth a King's ransom... how is this yours to give?
Bilbo Baggins: I took it as my one-fourteenth share of the treasure.
[Gandalf suppresses a smile]
Bard: Why do this? You owe us nothing.
Bilbo Baggins: I'm not doing it for you. I know that dwarves can be obstinate and pigheaded and difficult. They're suspicious and secretive, with the *worst* manners you can possibly imagine. But they are also brave and kind, and loyal to a fault. I've grown very fond of them, and I would save them if I can.
Thorin Oakenshield: [sees the homeless people of Lake-town] Those who have lived through dragon fire should rejoice. They have much to be grateful for.
Thorin Oakenshield: [calling down the hall, from the armory to Bilbo] Master Baggins, come here.
[Bilbo tentatively wanders over]
Thorin Oakenshield: You're going to need this.
[Thorin holds up the mithril shirt - the same one Bilbo gave Frodo in Fellowship of the Ring]
Thorin Oakenshield: Put it on.
[Bilbo takes it and slips it on over his shirt]
Thorin Oakenshield: This vest is made of silver steel. Mithril, it was called by my forebears. No blade can pierce it.
Bilbo Baggins: [laughing slightly at how he looks] I look absurd! I'm not a warrior, I'm a Hobbit.
Thorin Oakenshield: It is a gift. A token of our friendship.
[Bilbo offers a small smile. Thorin glances at the Dwarves in the armory, lowering his voice]
Thorin Oakenshield: True friends are hard to come by.
[Shoves BIlbo, none too kindly, further down the tunnel, out of earshot]
Thorin Oakenshield: I have been blind... but now I begin to see. I am betrayed!
Bilbo Baggins: [nervously] Betrayed?
Thorin Oakenshield: The Arkenstone.
[leans closer to Bilbo, lowering his voice even more]
Thorin Oakenshield: One of them has taken it.
[Both Bilbo and Thorin glance back towards the armory]
Thorin Oakenshield: One of them is false.
Bilbo Baggins: [carefully] Thorin... the quest is fulfilled. You've won the mountain. Is that not enough?
Thorin Oakenshield: Betrayed by my own kin...
Bilbo Baggins: N-no, uh. You made a promise to the people of Laketown. I-is this treasure truly worth more than your honor? Our honor, Thorin, I was also there. I gave my word.
Thorin Oakenshield: [Thorin smiles] For that, I am grateful. It was nobly done.
[smile fades]
Thorin Oakenshield: But the treasure in this mountain does not belong to the people of Laketown.
[sounding more and more like Smaug]
Thorin Oakenshield: This gold is ours. And ours alone. On my life, I will not part with a single coin. Not one piece of it.
Bilbo Baggins: [Bilbo stares across at him in despair and maybe a little fear as the Dwarves march by, fully armed]
Kili: I will not hide, behind a wall of stone while others fight OUR BATTLES FOR US! It is not in my blood Thorin.
Thorin Oakenshield: No, it is not. We are sons of Durin. And Durin's Folk, do not flee from a fight.
[Thorin and Kili do a headbutt]
Thorin Oakenshield: [to the rest of his company] I have no right, to ask this of any of you. Will you follow me, one last time?
Thorin Oakenshield: If more people valued home above gold, this world would be a merrier place
[Bard walks up to a destroyed entrance of Erebor]
Thorin Oakenshield: [slides into view] I am listening.
Bard: On behalf of the people of Laketown, I ask that you honor your pledge. A share of the treasure so that they might re-build their lives.
Thorin Oakenshield: I will not trade with any man, while an armed host lies before my door.
Bard: That armed host will attack this mountain if we do not come to terms.
Thorin Oakenshield: Your threats do not sway me.
Bard: [after a short pause] What of your conscience? Does it not tell you our cause is just? My people offered you help. And in return you brought upon them only ruin and death.
Thorin Oakenshield: When did the men of Laketown come to our aid what for the promise of rich reward?
Bard: A bargain was struck!
Thorin Oakenshield: A BARGAIN? What choice did we have but to batter our birth rights for blankets and food? To ransom our future in exchange for our freedom? You call that a fair trade? Tell me, Bard the dragon slayer, why should I honor such terms?
Bard: Because you gave us your word. Does that mean nothing?
[Thorin slides out of view]
Dain: I will not stand down before any elf! Not least this faithless Woodland sprite! He wishes nothing but ill upon my people! If he chooses to stand between me and my kin, I'll split his pretty head open! See if he's still smirking then!
Thranduil: He's clearly mad like his cousin.
Dain: Ya here that lads? We're on! Let's give these bastards a good hammering!
Dain: Good morning. How are we all? I have a wee proposition, if you don't mind giving me a few moments of your time. Would you consider... JUST SODDING OFF! All ye, right now!
Bard: Stand Fast!
Gandalf: Come now, Lord Dain.
Dain: Gandalf the Grey. Tell this rabble to leave or I'll water the ground with their blood.
Gandalf: There is no need for war between Dwarves, Men, and Elves. A legion of Orcs March on the mountain. Stand your army down.
Dain: I will not stand down before any elf! Not least this faithless Woodland sprite! He wishes nothing but ill upon my people! If he chooses to stand between me and my kin, I'll split his pretty head open! See if he's still smirking then!
Thranduil: He's clearly mad like his cousin.
Dain: Ya here that lads? We're on! Let's give these bastards a good hammering!
Necromancer: [Black Speech] Three Rings for the Elven-kings under the sky, Seven for the Dwarf-lords in their halls of stone,
Galadriel: Nine for mortal men doomed to die.
Gandalf: Don't underestimate the evil of gold.
[Thranduil's army of Mirkwood Elves arrives in Dale]
Bard: My lord Thranduil. We did not look to see you here.
Thranduil: I heard you needed aid.
[a carriage full of food approaches and the citizens of Lake-town rush to the carriage in relief]
Bard: You have saved us. I do not know how to thank you.
Thranduil: Your gratitude is misplaced. I did not come on your behalf. I've came to reclaim something of mine.
Bard: What news from the night-watch?
Alfrid: All quiet, sir. Nothing escapes me.
Bard: Except an army of Elves it would seem.
Bilbo Baggins: Who is that? He doesn't look too happy.
Gandalf: It is Dain, Lord of the Ironhills. Thorin's cousin.
Bilbo Baggins: [jogging to catch up to Gandalf] Are they alike?
Gandalf: [pauses] I always found Thorin the more reasonable of the two.
Kili: [as Tauriel is looking at the mass of Laketowners on the shores of the city, Kili approaches her] Tauriel...
Fili: [pushing a boat into the lake in order to reach Erebor] Kili, come on. We're leaving!
Tauriel: They are your people. You must go.
[She begins to walk away when Kili stops her]
Kili: Come with me. I know how I feel, I'm not afraid. You make me feel alive.
Tauriel: No, I can't.
Kili: [She again turns to leave, but Kili grabs her arm] Tauriel... amralimne'
['My love' in Khuzdul]
Tauriel: [Tauriel gives Kili a sharp look] I don't know what that means.
Kili: I think you do.
Tauriel: [Tauriel looks at him with curiosity in her eyes, but suddenly straightens up, sensing someone behind her. She begins speaking in Sindarin or Silvan Elvish] My Lord Legolas.
Legolas: [Also speaking in Elvish] Take your leave of the Dwarf. You are needed elsewhere.
Kili: [Kili and Tauriel turn away from each other, but both turn back as Kili takes her hand and gives her the rune stone his mother gave him. He closes his hands around hers and holds their hands between their hearts] Keep it... as a promise.
[He heads to the boat as Tauriel looks down at the stone, her eyes suddenly filling with tears as Kili, Fili, Bofur and Oin begin rowing towards Erebor]
