Nothing can bring their mum back - but tonight will be a rare moment of brightness in a dark year. And as they run out of the players' tunnel, it will be a chance for the two boys to remember Helen.
If George and William are nervous, their beaming faces don't betray it. Twelve-year-old George knew he would be running the ball out; William, 14, didn't find out till he arrived in Auckland that he'd join his brother.
"They don't probably realise how big a deal it is," Brett said. "We've been trying to scare them by saying there'll probably be half a billion people watching."
Today, the 2011 All Blacks have been dubbed "The Unshakeables" - and the two brothers deserve the same accolade.
Both George and William exuded a calm dignity as they met superstar Tana Umaga at Auckland Airport yesterday.
Brett attributed his sons' integrity to the example set by Helen. "They've looked after me as much as I've looked after them," he said. "They haven't dropped the ball at school. They've carried on. We knew it was going to take a long time to get over it. She was a pretty special lady and a fantastic wife and an awesome mother for the boys."
