Answer: John
John, his older brother, walked into the Ruettiger home to see Rudy staring at him. Frank arrogantly said, "Say Merry Christmas to your brother, Johnny boy". Rudy then left the house angry. His ex tried to apologize, but this just gave Rudy more of a reason to stay at Notre Dame. John was never the type to hurt Rudy, although he never really had faith in him anyways. He, as a child, was the good looking one of the family and when he grew up, the wealthiest.
