They get back together: For the first time since their breakup, Christian reaches out to Ana, sending her a bouquet of flowers and wishing her luck at her new job as Jack Hyde's assistant at Seattle Independent Publishing. Still broken up, Christian and Ana attend José's gallery opening as dates. They agree to get back together, on the condition that they will try a "vanilla" relationship.
The danger begins: Christian's ex-submissive, Leila Williams, begins to stalk Ana, sparking Christian to hire Luke Sawyer as a personal bodyguard for her. Soon after, Christian purchases SIP and Ana fears that he will interfere with her career. The couple then attends Christian's parents' annual charity ball; Ana meets his maternal grandparents, his therapist, Dr. Flynn, and Elena Lincoln aka Mrs. Robinson. Christian bids $100,000 to dance with Ana at the masquerade, inciting jealousy in Elena. That same night, Leila vandalizes Ana's car and breaks into Christian's apartment. Christian takes Ana to buy a new car, as well as shows her their potential future home. The next week, Jack Hyde assaults Ana in his office and is promptly fired from SIP; Ana takes over his job. Shortly after, Leila breaks into Ana's apartment and threatens her with a gun.
They get engaged: Christian confides in Ana about Leila, his past, and the truth behind his behavior. He proposes to Ana, but she delays giving him an answer. Ana meets with Christian's therapist, Dr. Flynn, to discuss Christian's issues. The next day, Christian gets into a helicopter crash but returns home safely. Relieved that he survives, Ana accepts Christian's marriage proposal on his 28th birthday. Christian announces his and Ana's engagement at the birthday party his family throws for him. Mrs. Robinson aka Elena Lincoln becomes hostile with Ana, accidentally revealing her own affair with him to her friend and Christian's mother, Grace. Kate discovers the previous dom/sub contract Christian had drawn up, allowing Ana to be honest with her friend for the first time. Christian takes Ana to the boathouse, which he has beautifully decorated, and proposes to Ana with a ring, which she accepts.
