The Hobbit: The Battle of the Five Armies culminates in three interconnected twist reveals that fundamentally reshape the narrative: Bilbo’s theft of the Arkenstone, Thorin’s discovery of this betrayal, and the unveiling of the Ring’s true nature. The Arkenstone theft serves as the emotional and political catalyst of the film’s climax, forcing characters to confront questions of greed, honor, and loyalty that define the entire trilogy. Director Peter Jackson uses these reveals to expose the consequences of obsession and to bridge the story toward the Lord of the Rings saga. The central twist—Bilbo’s removal of the Arkenstone from Erebor’s treasure vault—wasn’t driven by theft for personal gain but by moral clarity.
Bilbo, having witnessed the escalating tensions between Thorin’s Dwarves, Thranduil’s Elves, and Bard’s Lake-town humans, recognized that the Arkenstone was the singular object preventing peaceful resolution. By secretly handing it to Thranduil and Bard as leverage, Bilbo forced a negotiation mechanism where none seemed possible. The theft crystallizes Bilbo’s transformation from a reluctant adventurer into a character willing to sacrifice personal relationships for greater good. These reveal moments didn’t arrive randomly in the screenplay but were constructed to intensify throughout the third act, building from internal conflict within Erebor to external warfare between multiple armies and finally to the personal, existential revelation about the Ring itself.

Why Did Bilbo Steal the Arkenstone and What Changed Everything?
Bilbo’s motivation stemmed from pragmatic wisdom rather than greed or malice. He had observed Thorin’s complete psychological transformation into a figure consumed by gold-lust and the particular obsession with the Arkenstone—the most prized gem of the Dwarf treasure and Thorin’s ancestral birthright. Where Gandalf counseled restraint and Balin pleaded for reason, Bilbo alone moved to action, understanding that Thorin would never voluntarily compromise while the Arkenstone remained in his hoard.
The mechanics of the theft itself required Bilbo to navigate Erebor’s defenses and treasure chambers, a sequence that emphasized both his stealth capabilities and his newfound authority to make decisions that would affect kingdoms. When Bilbo surrenders the stone to Thranduil and Bard, he positions himself as the only figure capable of forcing the three armies toward negotiation. The limitation of this approach is that Bilbo accepts full personal responsibility for the consequences—if the plan fails, he bears the blame for betraying Thorin’s trust, which it ultimately does.
Thorin’s Betrayal and the Crisis of Obsession Unleashed
Thorin’s discovery of the Arkenstone’s theft marks one of Peter Jackson’s most visceral directorial moments in the trilogy. The scene cuts between Bilbo’s flight from Erebor and Thorin’s realization that his most prized possession—the heart of his greed and justification for refusing peace—has been removed from his hoard. Thorin’s rage is not merely about the missing stone but about the violation of his will, his ownership, and his authority over the dwarf kingdom. The betrayal cuts deepest because it comes from Bilbo, the only figure Thorin had accepted as a friend and trusted adviser. When Thorin confronts Bilbo, demanding the return of the Arkenstone and threatening to destroy him, Gandalf intervenes physically, blocking Thorin from killing the hobbit.
This intervention represents the structural moment where the film’s central conflict escalates from internal dwarf politics to open warfare. Gandalf’s protection of Bilbo, combined with his removal of Thorin and Dwalin from the tower, forces Thorin to face the approaching armies without the object of his obsession. The warning embedded in this sequence is that absolute ownership and control, once surrendered, cannot be quickly reclaimed. Thorin’s obsession with the Arkenstone had blinded him to military reality—the Elves and Lake-town forces were positioned outside his gates, and his refusal to share even a portion of the treasure meant they had nothing to lose by attacking. Bilbo’s theft paradoxically freed Thorin by removing the choice to hoard or to share, leaving only the choice to fight or to negotiate.
Thorin’s Redemption and the Battle Against True Evil
Following the Arkenstone revelation and Gandalf’s physical intervention, Thorin experiences a profound shift in consciousness. He regains what the film presents as his sanity—clarity about what truly matters. Where moments before he had threatened death to Bilbo over the stone, Thorin now recognizes his greed and selfishness as corruptions of his original purpose as king and protector. This isn’t a complete reversal written in a single speech but a gradual recognition that manifests when Thorin sees the true threat: Bolg and the Orc army, the actual enemy that had always existed beyond the gold-lust narrative. Thorin’s decision to lead the Dwarves into battle against the Orcs, despite his earlier obsession with treasure, demonstrates that the Arkenstone theft served as a moral catalyst.
The specific example of Thorin charging toward Bolg, weapon raised, shows a character reclaiming agency through sacrifice. His final confrontation with Bolg results in his death, a sacrifice that redeems his earlier failures as a leader and transforms his character arc from tragic obsession to heroic martyrdom. The emotional cost of this redemption is high. Thorin never explicitly thanks Bilbo or acknowledges that the hobbit was right, creating a bittersweet resolution where moral clarity costs both Thorin’s life and permanent reconciliation with his friend. The film uses this distance—the lack of full resolution between Bilbo and Thorin—as a reminder that redemption doesn’t always include complete absolution or emotional closure.
The Ring Revelation and the Connection to Lord of the Rings
In the film’s final scenes, Gandalf makes a discovery that represents the third major twist: he reveals he knows about Bilbo’s magical ring. This is not an accusation but a recognition, a moment where Gandalf acknowledges that Bilbo has carried the Ring throughout the entire Hobbit trilogy. When confronted, Bilbo initially denies possession, a reaction that suggests the Ring’s corrupting influence over even small deceptions. Gandalf’s knowledge of the Ring serves multiple narrative purposes.
First, it establishes that Gandalf has known the Ring’s location all along but has chosen to monitor rather than control Bilbo’s choices. Second, it creates dramatic irony with viewers familiar with the Lord of the Rings films, where the Ring’s power and significance expand enormously. Third, it positions Bilbo’s possession of the Ring as a continuation of his moral complexity—he has done good (the Arkenstone theft) while harboring a corrupting influence (the Ring he cannot surrender). The comparison here is instructive: the Arkenstone was an external object that drove Thorin’s obsession, but the Ring is an internal corruption that Bilbo cannot fully acknowledge even to himself. The difference suggests that some temptations operate through self-deception rather than overt greed, making them harder to identify and resist.
Kíli’s Death and the Personal Price of War
Among the fallen in the Battle of the Five Armies is Kíli, the young dwarf killed by Bolg himself. Kíli’s death carries particular weight because his character had been positioned throughout the trilogy as younger, more idealistic, and somewhat naive compared to his uncle Thorin. The specific detail of Bolg choosing Kíli as a victim suggests a deliberate cruelty—not merely battlefield chance but targeted destruction.
Tauriel’s mourning of Kíli provides one of the film’s most emotionally raw sequences. Her grief is not only personal—she had developed romantic feelings for the young dwarf—but also representative of the futility of the conflict. Despite all the political maneuvering, the theft of the Arkenstone, and the recognition of shared enemies, young warriors still die in battle. The limitation of Bilbo’s entire moral project is that it could not prevent all death or suffering, only redirect it toward a more meaningful target (the Orc army instead of three kingdoms fighting each other).
Peter Jackson’s Direction of Revelation Pacing
Peter Jackson uses visual and audio cues to emphasize these reveal moments rather than relying on exposition. When Bilbo steals the Arkenstone, the scene is largely silent except for the character’s breathing and footsteps. When Thorin discovers the theft, Jackson cuts rapidly between Thorin’s growing realization and Bilbo’s escape, using intercutting to build tension without dialogue.
When Gandalf confronts Bilbo about the Ring, the conversation occurs in quiet tones during a peaceful moment, creating stark contrast with the preceding battle sequences. This directorial approach—prioritizing visual storytelling over explanation—distinguishes Jackson’s handling of these reveals from simpler narrative exposition. The films trust viewers to understand motivations through action and consequence rather than characters explaining themselves at length. The Arkenstone theft is revealed through Bilbo’s actions, not Bilbo’s internal monologue; Thorin’s transformation is shown through his choice to fight, not through a speech about redemption.
The Arkenstone’s Symbolic Function Beyond Plot Mechanics
The Arkenstone operates on multiple levels simultaneously: as a literal object of value, as a symbol of Thorin’s corrupted authority, and as a moral test for Bilbo’s character. In Tolkien’s source material, the Arkenstone functions primarily as treasure. Peter Jackson’s adaptation elevates its significance to represent the specific temptation of ownership and possession that consumes Thorin. The film suggests that some objects become dangerous not through their inherent properties but through what characters project onto them.
Bilbo’s recognition that the Arkenstone must be removed—not destroyed, but taken into different hands—reveals a sophisticated understanding of power dynamics. The stone doesn’t lose value or meaning; it simply changes hands and becomes a tool for negotiation rather than a reason for war. This distinction matters because it shows Bilbo didn’t solve the problem through theft but through repositioning, placing the object in a context where its power could be used differently. Bard and Thranduil, upon receiving the Arkenstone, use it immediately as Bilbo intended—not for personal possession but as leverage to force Thorin to the negotiating table, transforming the stone from a symbol of obsession into a symbol of necessary compromise.
