Has Australia's outspoken alpha male, swimmer James Magnussen, suddenly turned shy?
The world champion 100 metre freestyler, renowned for his bravado, made his Olympic debut on Sunday morning at the London Games.
But after helping Australia win its 4x100m freestyle relay heat, Magnussen - for the first time in memory - had nothing to say to journalists.
Completely out of character for the brash 21-year-old, he instead fed reporters a line through the Australian swim team's media manager.
"I felt nice and relaxed coming down the first 50 and just let the crowd carry me home at the end," Magnussen said via the media man.
And that was that - no promises; no warnings for the world; he'd turned into a silent Missile.
Magnussen, swimming the final leg, clocked 47.35 seconds in the relay heat and was the fastest of the Australian quartet.
He dived into the pool with his nation second behind the United States, but from the moment he made a splash it was inevitable Australia would win.
Magnussen duly left America's Jason Lezak in his wake to confirm Australia's favouritism for Sunday night's relay final - guess we'll hear about it later.
