Former Hampshire star Pietersen achieved a notable step towards completing his 'reintegration' after his summer of discontent, taking the field for his adopted country for the first time since being dropped for the final Test at Lord's more than two months ago.
The South Africa-born batsman's route back to favour has been a tortuous process, involving face-to-face talks with management and senior players and a public show of contrition for his controversial behaviour.
But if there was any lingering resentment following the breakdown in relations over contract wrangles, "provocative" text messages and that spoof Twitter account, it was not in evidence - from a distance at least - as England and Pietersen reacquainted themselves on the field at the start of what is sure to prove a tough Test series against India.
Tim Bresnan confirmed that observation as he reflected on a taxing day one of three in the tour opener, which India A finished on 369 for nine at the Brabourne Stadium.
Number six Manoj Tiwary top-scored with 93, after Yuvraj Singh and Abhinav Mukund had both also hit half-centuries, as the hosts flourished despite three hard-earned wickets each for seamer Bresnan and off-spinner Graeme Swann.
As for the inevitable Pietersen issue, Bresnan said: "It's pretty much business as usual. I don't suppose you'd be able to see from the outside looking in ... that it's anything than normal.
"I'm pretty sure most of the lads in the dressing room were expecting it to be like that - and that's what it was like.
"For the lads, it's nothing different to having [any] player come back into the squad who's been missing for a while."
It is already well documented that Pietersen's return has been achieved only after a series of meetings with new Test captain Alastair Cook and other players.
"Everyone in the know has sat down and spoken about it," added Bresnan.
"But apart from that, for the rest of the boys, I guess it's just like having someone who's been injured coming back into the side.
"There's nothing exceptionally different.
"He's the same old Kev - energy in the field that he showed today, all day.
"He's just Kev. It's been good."
Bresnan had to bowl 20 overs, once Finn managed just four before limping off and leaving England with only two frontline seamers.
"Obviously, we're disappointed one of our fast bowlers had to go off," said the Yorkshireman.
"But it's one of those things where you just have to step up a bit, and each of you has to take on his responsibility."
Finn was set to have a scan this evening, and an update on his fitness is anticipated tomorrow.
Bresnan said: "We're not sure what's happening. The doc will check him out back at the hotel.
"All we know is it's hurting, and scans will reveal more."
