The hit on Ace was authorized....and it was Nicky's last chance.The bosses back east clip Andy Stone, just to be safe. Nicky suggests they wouldn't have bothered if Andy had been italian. So the bosses deal with him, but they let jewish bookie Sam "Ace" Rothstein live? No way. They went to Nicky and said, "Take out the jew and all is forgiven." He tries a car bomb, but thanks to a balance problem and a metal plate, Ace lives. And the mob don't like it when you blow a hit. Thus, Nicky and his brother get a Texas Funeral. And that's that.
