In Eclipse, two-year-old Claire and her sister were down from the Makah reservation visiting their aunt Emily when she was imprinted upon by Quil. The explanation of "imprinting" in Eclipse ensures that Quil only wants what is best for Claire, and that he has absolutely no romantic feelings for her. Later in life, he will be like an older brother, and then, when she is old enough, if Quil is what she wants, they will form a romantic attachment, like Sam and Emily. Claire makes a brief appearance in Breaking Dawn with Quil, playing on First Beach. It is obvious that she and Quil enjoy each other's company.
The character of Claire and the controversy of Quil imprinting on her acts as foreshadowing to Jacob imprinting on Renesmee, the child of Bella and Edward Cullen, during the events of Breaking Dawn. Shape-shifters have previously imprinted on individuals of roughly their own age, and the relationships have assumed a romantic tone. Quil's imprinting on Claire demonstrates the fact that the imprinter becomes whatever his imprintee needs, including a protector, a friend, a confidant and so on.
