Pietersen revels in his coronation
Bang on time, he stepped out of the lifts at the Lord's media centre, flashed his Colgate smile and even rolled his eyes as the cameras clicked away manically. If he blinked once when the flashes went off, we never saw it.
National selector Geoff Miller, in his flat Derbyshire vowels, revealed the news we already knew, and nobody listened - least of all Kevin Pietersen himself.
The photographers were camped in a little huddle down to his left and he faced them first, raised his eyebrows, and - remarkably - mouthed the words "Cheers, mate" to one.
Premier League football clubs do a lot of "unveiling" of their new players in August. This, on the other hand, almost had the air of a coronation about it.
Not that Lord's would ever have seen anything quite like it before, as Pietersen set off his smart blazer and monochrome striped tie with a dainty little lapel badge - there had to be one concession to bling - and smiled and smiled and smiled.
The contrast between this and the tearful abdication of Michael Vaughan halfway up the country exactly 24 hours earlier could not have been more stark.
It soon emerged Pietersen had spent much of Sunday watching television, first absorbing the news that his predecessor had resigned - "I was straight on the blower to Mike," he said - and then taking in the development that he had emerged as the front-runner to replace Vaughan.
Later in the afternoon he was invited to be the new England captain. After a few more phone calls, this time to family members, he drove to Loughborough to have his first meeting as England captain with the coach Peter Moores, whose job he could save if he turns around some dispiriting recent results by the team.
Now it was time to meet the nation's media. Pietersen answered questions for about 20 minutes with grace and did not resort to the sort of wisecrack remarks we have occasionally heard from him in the past.
For example, when he stood in for the suspended Paul Collingwood in the last one-day international against New Zealand in June, he glibly admitted he had "zilch" experience of the role, before adding "If we do everything we said at our team meeting, I'll be smoking a cigar at mid-off."
Now given the role on a long-term basis, there was a much more serious presence about him.
He only had one awkward delivery to contend with, when the Daily Telegraph's Derek Pringle asked him if he was planning to get a new tattoo.
"What kind of tattoo, Derek?" asked KP. "I don't know, maybe one saying skipper," replied Pringle. "I'm not sure about that." Six runs to Pietersen, and laughter all round.
So has the ECB done the right thing to make Pietersen captain? Vaughan said his decision to quit was "both the hardest and the easiest decision" he had made. And in some ways making KP Vaughan's successor is both the obvious one and the biggest gamble.
Ian Botham was, like Pietersen now, England's superstar back in 1980 when he was made England's captain. Twelve Tests later, and no wins, it all ended in bitter acrimony and Botham only regained his match-winning exploits when Mike Brearley returned to the captaincy.
The next great hero, Andrew Flintoff, was unwisely promoted above Andrew Strauss - who had just led England to a Test series win over Pakistan - but floundered in Australia as the Ashes were meekly surrendered in 2006-07.
Similarly, there must be a genuine fear that Pietersen's brilliant batsmanship will be compromised by the responsibility of captaincy - and the twin concerns will work against each other.
Or, the occasional mad shots when he throws his wicket away on the verge of reaching a century will be tempered because he is now "wearing the stripes". And the natural self-confidence we see in his batting could in fact make him a bold and decisive leader.
Will Pietersen be one of the great thinkers of the game like Brearley? A great tactician like Vaughan? Or will he be a take-no-prisoners ruthless leader in the Australian mode, best exemplified by Steve Waugh?
He will probably be none of those things, and though he pledged to "always look for advice" one cannot help but feel he will do things with a self-assured swagger that just might help England recover the self-belief that has visibly drained away of late.
Pietersen says he is very much "gut-instinct orientated" when he plays his cricket and believes those instincts have assisted him tremendously.
Whatever those gut instincts are, we know the Kevin Pietersen ride will be an adrenaline-filled one - and it could either go spectacularly, horribly wrong or be a surprising, storming success.
