This is Jack's first time meeting Ma's mother, and he doesn't yet understand that he can just call her "Grandma" instead of "the Grandma." It takes Jack a while to understand that everyone has a family, not just Ma, and that her family is his family, too.

Defining family isn't easy, especially when the family is as complicated as this one. Grandpa has trouble accepting Jack as an addition to the family. To Grandpa, Jack is only evidence that his daughter was raped. He can't see Jack as his Grandson, only as that horrible reminder.

Ma definitely thinks that an intense bond between mother and child instantly exists. She'd do anything to protect him, so when the talk show host asks her if things were "difficult," Ma doesn't think of it that way. It wasn't hard or easy; it's just what she had to do.
