Final answer:
The provided text does not contain the specific information about what Grans tells Via in the book 'Wonder.' 'Wonder' is a novel by R. J. Palacio about a boy with a facial difference and does not match the texts referenced.
Step-by-step explanation:
From the context given, the specific passage that refers to what Grans tells Via in the book Wonder is not provided, and it appears the passages mentioned do not correlate with the book in question. Wonder is a novel by R. J. Palacio about a boy named August Pullman with a facial difference. It focuses on themes of acceptance, kindness, and friendship. Via is August's sister who also has her own perspective and experiences shared in the novel. In the absence of a direct quote or a passage from Wonder, I am unable to provide the exact information on what Grans tells Via.
