Infertility has made Eloise fearful that she can't create the type of family Ollie would want, but Alice tells Eloise that she can still create a full, real, and loving family despite her infertility.

Eloise reveals that her own permanent infertility made visiting Alice after her miscarriage too traumatic for her. In place of Paul convincing Eloise to go through with her marriage like in the novel, that responsibility goes to Alice in the film. In the film, it is revealed that Alice and Eloise became estranged after Alice suffered a traumatic miscarriage and Eloise did not come to her side. However, the movie version of The People We Hate At The Wedding changes this storyline to give it a deeper meaning that is more focused on the themes of motherhood and unconditional love present in much of the rest of the film. In the book, Paul is the one to convince Eloise to go through with her wedding. In a departure from the novel, the film adaptation of The People We Hate At The Wedding sees half-sisters Eloise and Alice bond with each other over their shared fertility struggles. With it having been revealed that Donna and her children have healed their estranged family at the conclusion of The People We Hate At The Wedding, Donna takes the opportunity to rediscover herself and travel the world. Her children's love is enough and she instead decides to prioritize the family dynamic in her life instead of bending over backward for romance. Earlier in The People We Hate At The Wedding, after coming to the defense of her children in a hilarious fistfight at the wedding rehearsal dinner and landing in jail, Donna realizes that she doesn't need to rely on a romantic partner to feel unconditional love. The photo and the message written on it - a reference to Eat, Pray, Love - reveal that Donna has moved on from her failed romantic relationship with Henrique and the pain of her late husband, Bill, and has begun to focus on herself and her own happiness. A photo of Donna ' Eat, Pray, Loving it across Greece' is shown during the end credits. Viewers may not have seen the entirety of Donna's happy ending in The People We Hate At The Wedding if they didn't stick around for the closing credits of the film.
