They get married: Christian and Ana get married and honeymoon in Europe, sailing on his boat, The Grace. After an argument, Ana agrees to take Christian's last name, becoming Mrs. Anastasia Grey. As a wedding present, Christian gives Ana SIP; she renames it Grey Publishing.
Things get complicated: While Christian is away on a business trip, Ana discovers Jack Hyde in their apartment. Though disarmed by security, he had intended to kidnap Ana. To help take her mind off of things, Christian surprises Ana with a trip to their estate in Aspen, bringing along Mia, Elliot, Kate, and Kate's brother, Ethan. While there, Elliot proposes to Kate, making Kate Ana's future sister-in-law. When they return to Seattle, Ana's father, Ray, gets into a car crash; while visiting him at the hospital, Ana learns that she is pregnant.
The final fight: Ana tells Christian of her pregnancy and he accuses her of getting pregnant on purpose; this, along with Christian's recent contact with Elena, prompts a tense disagreement, and the two don't speak for days. Ana learns that Mia has been kidnapped by Jack Hyde, who is demanding a ransom; Ana pretends to leave Christian and takes money out of the bank to rescue Mia. Believing Ana truly doesn't love him, a heartbroken Christian agrees to let Ana go.
The ending, and flash-forward: Hyde attacks Ana out of anger, beating her to unconsciousness and causing her to almost lose her baby. Fearing that he had lost Ana forever, Christian realizes that Ana always loved him and warms to becoming a father. Two years later, Ana has given birth to a son named Teddy and is six months pregnant with their daughter.
