The narrative's key revelations and resolutions hinge on sacrifice, deception, and emotional reconnection:
- Mjolnir's Secret Enchantment: Flashbacks reveal that Thor subconsciously enchanted Mjolnir to always protect Jane during their relationship. When Jane develops terminal stage-4 cancer, the hammer calls to her in New Asgard and reconstitutes itself to grant her godlike strength.
- The Double-Edged Hammer: While wielding Mjolnir temporarily revitalizes Jane, each transformation purges the chemotherapy drugs from her system, causing her cancer to advance rapidly in mortal form.
- Gorr's Strategy: Gorr kidnaps New Asgard's children not to murder them, but to lure Thor and steal Stormbreaker, the key required to summon the Bifrost and open the gates of Eternity.
- Climax and Ending: Thor shares his lightning powers with the captive children to defeat the shadow army, while Jane uses Mjolnir's shattered pieces to destroy the Necrosword. Entering Eternity, Thor refuses to duel Gorr and instead chooses to spend Jane's final moments holding her. Moved by their devotion, Gorr renounces his genocidal wish and instead asks Eternity to resurrect his daughter, Love. Jane dies in Thor's arms, transforming into golden stardust to enter Valhalla, while Thor adopts Love as his traveling companion and apprentice.
- The Title's Double Meaning: Love and Thunder refers not only to the thematic balance of the film, but literally to the heroic partnership formed in the finale—Thor (Thunder) and Gorr's revived daughter (Love).
