At the unsettling conclusion of Gone Girl, the baby is biologically Nick Dunne's, conceived by Amy Dunne. This pregnancy serves as a final, chilling act of manipulation by Amy, ensuring her permanent hold over Nick.
The Conception: A Calculated Move by Amy Dunne
Amy Dunne's pregnancy is not a spontaneous event but a meticulously planned component of her scheme to solidify her control over Nick. After her dramatic return and the subsequent media frenzy, Amy masterfully orchestrates her transition back into Nick's life.
To achieve this, she conceives the baby using Nick's sperm, which she had previously saved. This foresight highlights the depth of her planning:
- Strategic Acquisition: Months prior, Amy had tricked Nick into visiting a fertility clinic under the guise of exploring options for them to have children. During this visit, she managed to obtain and store his sperm.
- Engineered Pregnancy: When she decides the time is right, after framing him for her disappearance and orchestrating her return, she uses this saved sperm to become pregnant. This move is designed to create an unbreakable bond, ensuring Nick cannot truly escape her, especially with a child involved.
Why the Baby Matters to the Plot
The existence of this baby profoundly impacts the narrative and the characters' fates:
- Ultimate Control: For Amy, the baby is the ultimate weapon, a tangible tie that binds Nick to her forever. It forces him into a familial role he cannot easily abandon without facing severe social and legal repercussions.
- Public Perception: In the eyes of the public and the media, the baby solidifies their image as a family, making it nearly impossible for Nick to expose Amy's true nature without appearing heartless or unstable, especially as he's already been portrayed as the villain.
- Tragic Ending: The baby's impending arrival represents a dark, cyclical conclusion for Nick, who is now perpetually trapped in a toxic relationship with the woman who systematically destroyed his life, all under the guise of building a family.
Key Aspects of the Baby's Parentage

| Biological Father | Nick Dunne | His sperm was used for conception. |
