Having spent much of the conversation biting his tongue as he listened to his older brother Niall recount childhood stories, some more embarrassing than others, a wry smile is slowly etched across Rory Scannell's face.
For a player who specialises in timing his runs on the pitch, Rory does the same off it, as he sits quietly and takes the kind of slagging that only an older sibling can dish out.
Suddenly, the penny drops as to why Niall is so eager to get his punches in first.
"All of my stories will be told at the wedding, don't worry," Rory grins.

Niall's face turns a little paler: "You have been threatening a lot in the speech all right. That's why I want to get my stories in here first!"
This August in Killarney, Rory hopes to get his turn to dish the dirt as the best man for his big brother's wedding.
There is nothing quite like an Irish family gathering and this mini version at Munster's High Performance Centre in Limerick offered a fascinating insight into a special bond that began in Cork and came full circle in New Jersey.
Wavered Just 20 months separate Niall (28) and Rory (26), who first played together for Munster five years ago.
They have come a long way since playing underage GAA with Douglas and soccer with College Corinthians before rugby really took a hold during their time in Pres and Dolphin.
The pair have been there for each other through thick and thin and although a lot has changed in the years since, their close friendship has never wavered.
What makes the Scannells' story all the more unique is that they don't come from a strong rugby background.
Their father Bill was much more of a soccer man, while their mother Emer's family are steeped in GAA as their grandfather Donal O'Sullivan won two Munster football titles with Cork.
Instead, the only real rugby links they had was through their uncle Tadhg O'Sullivan, Munster's long-time team doctor and father of academy player Jack who is currently breaking through with the senior team.
Just before Covid-19 brought the season to a shuddering halt, Niall captained his province for the first time in a 28-0 win over Zebre and although he was forced off early with an ankle injury, a proud day for the family was made even more so by the fact that Rory and Jack O'Sullivan were also in the starting team that evening.
The Scannells grew up in Douglas with their younger sister, Kate and brother Billy, who was in the Munster Academy up until last year, before making an exciting move to France to join Biarritz.
Theirs was a typical Irish upbringing in that Bill and Emer would taxi their kids all over Cork city to their different training sessions.
Before the question is even asked, Rory knows exactly what Niall is going to say regarding his earliest memory of them playing together.
"Rory crying in the street leagues in Douglas when he was about four," Niall laughs.
"Every single Saturday, bawling crying, 'I don't want to play.' He was crap as well!
"He cried when he went to everything. I used to get called down to his classroom all the time and be told by the teacher, 'Rory has been crying all morning again'.
"Then when we were around 10 or 11, that was when I knew Rory was way more skilful at everything. I was more of a hard worker."
Rory's memory of those younger days may not be as fresh as Niall's, but the pair have no problem remembering a particular U-14 football match when the older sibling made it clear that for all the fighting they would do with each other, he would always be there for him.
"I remember a time when we were playing football," Niall recalls.
"I was full-forward, Rory was corner-forward and Alan Cadogan (Cork hurler) was in the other corner. The two lads were absolutely tiny, playing my age-grade.
"I think it was either up in the Glen or Na Piarsaigh, somewhere on north side of Cork City anyway, and we were getting absolutely killed.
"The two lads were constantly getting ridiculously fouled. I remember freaking out, but other than that Rory was always well able to handle himself in fairness."
As Niall moved through the years at Pres, he watched the likes of Peter O'Mahony and Simon Zebo forge the path into the Munster Academy, so by the time Rory was on the same route he was able to follow Niall.
"Having Niall there was a lot easier because he showed me the ropes in the first year," Rory maintains.
"Watching him win the Junior Cup when I was in first year in school really spurred me on.
"We always hung around together, in the same friend group. Playing on the same teams and being in school together, we would have spent a lot of time together. We were never too far apart."
Although their paths didn't cross with Billy in Pres, Rory was given the responsibility to look out for him in primary school.
"Billy was like me, he cried the whole way through junior and senior infants, so I used to get called in. It was a bit of a continuous cycle in our family!"
Looking back on it now, the childhood scraps helped forge the strong bond that Munster supporters see before them today. Even though the petty squabbles would often spill over, there has never been any bad blood between them - as much as that was tested.
"Rory was tiny until we were about 14. I was way bigger than him but he is fiery enough - as you can see on the pitch, he has got a bit of a temper.
"In any fight we would have, I would absolutely pummel him; he'd get fired up, run off and I would have to hide and lock a door because he would just come back with a weapon of some kind.
"The one fight that stands out the most was when I hit him with a golf club and split his eye. He hit me back with a hockey stick and split me open.
"Tadhg, the doctor here (in Munster), used to live next door. Our mum had to bring us both in next door to get stitched up because there was blood absolutely pumping everywhere."
Rory Scannell: "What about the time we were boxing with gloves and you knocked my front tooth out?"
Niall Scannell: "Oh yeah! You're left-handed and I'm right-, so our parents thought if they only got us one pair of gloves, we wouldn't knock the heads off each other. But I took the right glove and you took the left. They weren't sure if the tooth was a proper tooth or a baby tooth."
RS: "It was a baby tooth, thankfully!"
NS: "Yeah, I definitely got away with one there!"
Their parents have been there every step of the way and while they may not always have been big rugby fans, they are at the stage now where at the beginning of every season they map out their year according to Munster's schedule.
February 14, 2015 will forever be a special day as it marked the first time that the Scannells played for Munster together, as Rory started at out-half and Niall came off the bench at hooker in the win over Cardiff Blues
If that was memorable, then June 10, 2017 was even more so, as the brothers lined out for Ireland in the summer tour win over USA in New Jersey.
Massive For all of the talented pairs of brothers who have come through Munster over the years, the Scannells became the first to line out together in an Ireland Test during the professional era.
A week later in Japan, they started an international alongside one another, as they followed the likes of the Kearneys, Bests and Easterbys in achieving the remarkable feat.
"When you look back on it, it is a massive achievement," Rory admits.
"Playing together was just the norm for us, but when you think about it, very few siblings have done it for Ireland and Munster. It's a bit surreal."
Those kind of achievements have been recognised at home too - although their sister Kate often points out that she doesn't feature as prominently on the walls.
"As soon as you walk in the door, there are jerseys and caps hanging up," Rory explains.
"My sister is always giving out that none of her stuff is up on the wall!
"My dad seems to change his mind about who the favourite is depending on how games, results and performances are going. Billy was home recently, so he was the number one son."
"I went for coffee with dad actually and noticed that Billy is on his phone screensaver at the moment," Niall says.
"It used to be Rory running past Ma'a Nonu (for Toulon) and I would wonder, 'is that because he is running past Ma'a Nonu or does he legitimately prefer Rory!'
"Like Rory said, it is a bit cyclical depending on how things are going."
For all the many good times that they have shared, there have been some low moments too - not least earlier his year when Niall and Rory were left out of Ireland's Six Nations squad, despite being involved in the pre-Christmas camp.
For Niall, it was much more of a shock given that he was the second-choice hooker at last year's World Cup and looked set to replace the now-retired Rory Best.
Rory, on the other hand, knew he had ground to make up on his rival centres.
"When you don't get into an Ireland squad and you ring your parents, you can feel that they are absolutely gutted," Niall maintains.
"It isn't a nice feeling, so I try to keep it on an even keel and not get them too hyped up about the highs or the lows.
"I remember chatting to you one day and I had got into the Ireland team, but Rory hadn't. That kind of scenario must be hell for my parents."
"It was easy enough this time though because we both missed out on the squad," Rory laughs.
"'Faz' (Andy Farrell) is just going to start ringing our parents from now on," Niall quips.
"Rory had it a bit in 2017. He was in the Six Nations squad and I was out injured, not really getting a look-in at all. Then he got dropped out of the squad for the Wales game and I got called up.
"My mum was just going, 'when are we going to get both of ye in there at the same time?!'
"I think it helps that we are in vastly different positions. I don't envy Rob and Dave Kearney in that one of them making the squad, unfortunately, means one probably doesn't.
"Naturally that happens a lot with brothers because of genetics and stuff, a lot of the time you are going to be quite similar. But we are obviously not.
"It's a bit different with Billy. If he was still here, unfortunately every week I get picked, he's not. I don't envy that situation. That's tough because at least if Rory is in and you're not, you still have that emotional investment."
They have had to put the disappointment of Billy, a hooker like Niall, getting released by Munster to one side, even if that was easier said than done, as Niall admits: "He was living with Rory at the time, but I would be very protective of Billy because he is so much younger (seven years) than me.
"To be honest, I was probably a bit p****d off about it because I see how hard he works behind the scenes. You would be a bit... not bitter, but thinking maybe that's a bit harsh. You just have to take the subjectivity out of it.
"It is a bit s**t but we were over with him recently and he is loving life in France. You wonder does that all happen for a reason.
"It's a bit s**t too in the sense that when he was home, we were throwing together at Irish Independent Park. I'd like to be able to help him out more in those scenarios, but it's hard now because he is away."
Impact The trio's paths may well cross again further down the line, which would really complete this fascinating story.
Rugby may be on hold for now, yet the burning desire to play at the very highest level again hasn't stopped for either of the Scannells.
Rory insists that he needs "to have a bigger impact in the big games", while Niall is honest enough to admit that he was "p****d off" and "surprised" when he got dropped from the international set-up.
The ultimate goal is to get back into the Ireland squad, but closer to home they are determined to win silverware together with Munster for the first time.
"It would be unbelievable," Niall adds.
"When I retire and think back of my standout memories of playing with Rory for Munster and Ireland, ultimately, we want to have won trophies together That's what it is all about really."
