In Carolline Ruiz's view, it really wasn't a big deal whose last name the child took. However, that's just the way things were in Z Country - if a child took their mother's last name or any other last name other than their father's, people would always look at the child and the child's mother with colored glasses.
It was because of this environment that Carolline Ruiz had never been concerned about what last name her child would have; the child would have the Hawkins name anyway.
Although Mia Parker was right about one thing - if Ben Parker really got together with her, he would indeed have to be the son-in-law entering her family. Given Mia's uncle's unbounded love for her, if any man dared to snatch her away from him, he would definitely fight them to death.
The Ribs Pot Restaurant arrived quickly, and Mia Parker paid the fare, urging Carolline Ruiz to join her as they got off and entered the place.
