Of course we don’t know what happened to Tony’s daughter when she walked into the restaurant, do we?

My opinion: Godfather III gives the clue.
In an interview, Chase later said that Carmela never remarried, Meadow became neither a doctor nor a lawyer, and AJ went to Los Angeles to produce pornographic movies for the Brooklyn crime family as restitution for what they did to his father.
She came in right on time to see what happened.
