"It's never been my position," said Kenny. "I've jumped in there about five times in my career, when Smithy [Cameron Smith] comes off ... for about 10 minutes or something. But any place I got, I was willing to put my hand up and accept."
After a string of withdrawals, Kenny was called into camp as the 19th man. He wasn't lined up to play, until coach Stephen Kearney made a decision just before the captain's run on Thursday.
"I was stoked, I couldn't believe it really," said Kenny. "Everything just fell into place. I rang my dad and I don't think he could believe it, he sounded so happy. We were both over the moon."
Bromwich saw almost 30 minutes of action, contributing 22 tackles and a couple of charging runs.
"I didn't feel out of place out there," said Kenny. "A couple of passes didn't find the mark which wasn't good enough but otherwise I did all right."
The Bromwich brothers continue a proud New Zealand tradition.
Kurt and Dane were the first Kiwis siblings of the modern era, before Nick and Owen Wright in the 1980s, along with Joe, Tea and Iva Ropati.
In the 1990s to early 2000s, it became quite common: Kevin and Tony Iro, John and David Lomax, Henry and Robbie Paul, Vinnie and Louis Anderson. Before last Friday, the most recent were Jason and Nathan Cayless.
"It was a long way from the back yard where we used to play in Manurewa," said Kenny. "It was always me and my sister, or me and a friend, versus him. Jesse used to dominate - he's always been big - but we used to get him a couple of times too."
Great Kiwis brothers
Dane and Kurt Sorensen: Teamed up with Cronulla and their country. Two of the best forwards of their generations, whose careers were interrupted by a transfer ban.
Henry and Robbie Paul: Almost unstoppable as a halves duo, though both could play hooker. Unfortunate that most of their careers were in the Northern Hemisphere.
Kevin and Tony Iro: Played together for Wigan and Manly. Starred in some famous Kiwis wins in the 1990s.
