They are twins, they are mates, they live together and they play for the same team.
But now Huddersfield Giants’ Innes and Louis Senior are taking sibling rivalry to another level.
The tall, strapping, 21-year-olds both came through the academy system of hometown Huddersfield to show their quality. Both as wingers.
However, with England star Jermaine McGillvary on the right flank, two into one simply does not go on the left. Ever-present Innes, who spent the last two seasons on loan at tonight’s opponents Wakefield, currently has the role in Ian Watson’s side.
However, despite six tries in 12 games, he knows his brother is always snapping at his heels.
What is that dynamic like? He explained: “I’ve been playing so I’ve not had that frustration that Louis might have. But we’re both really quite happy if the other’s playing well as it reflects well on both of us.
"Because we’re twins, if people see a good performance from one, they think the other’s good as well so really we’re rooting for each other selfishly and as family.
“We both played the first game of the season against Toulouse and for the second (when McGillvary was fit), Watto was unsure who to play right up until the day before. I just edged out Louis. After that, I’ve been just lucky to play pretty consistently well. But Louis’ been pretty unlucky: I could just have easily been in the same situation.”
The pair still live with their parents at Meltham near Huddersfield and understandably have always been close.
“We’ve always been mates as well as brothers,” said Innes, as sixth-placed Giants bid to bounce back from successive defeats.
“We’ve the same friends outside of rugby and always grew up with the same mates. We never argue. We’re hoping to move out towards the end of the year but not together - we’ve got girlfriends so we’ll be moving out with them!”
On his own battle to get in to the side, Louis conceded: “It is frustrating as I know I’m good enough to play Super League. I’m getting the odd game here and there but not consistently playing. But I am happy for Innes.
"We’ve always been competitive, wanting to beat each other. We used to get mad when we’d lose against each other as kids, at table tennis or whatever. To be a professional sportsman, you have to have that competitive nature yet both of us are quite laid-back as well. We’re not confrontational so we don't argue with each other or anyone really.”
It is a nice conundrum for Watson to have but does the coach ever get them mixed up?
Louis revealed: “Yes - but he’s not the worst! We’ve definitely got different features but there’s still a few players who have no idea. Chris Hill and Danny Levi just call us Twinny and make no effort whatsoever!"
Meanwhile, he has enjoyed having his twin back after those two years away at Trinity - even if his brother has jumped ahead of him in the queue for wing spots.
"It is good having him back and it gives me someone to do my extras with," said Louis, who debuted against Leeds aged 17 in 2018, just days before his brother made his own bow.
"We both need to work on the same things so it’s handy having that training partner in the gym or whatever. We keep on pushing each other as if someone’s lifting a certain weight then the other one doesn’t really want to be falling behind.
"Everyone is disappointed with our performance against Warrington and we all want to bounce back. I only did the warm-up but I could tell it was flat. There was no energy or anything which is unusual for us so far this season."
Huddersfield's impressive start was slowed when they failed to pick up a win over Easter, drawing at Leeds, losing 24-12 at home to St Helens and 32-10 at Warrington on Saturday. They will look to get back to winning ways at Wakefield as Innes makes his return to the club where he scored ten tries in 22 games during those loan spells.
He said: " I loved it at Wakey and it just gave me that game time and confidence that I really needed. At the time, I was fourth choice winger at Huddersfield behind Jermaine, Darnell (McIntosh) and Louis so it was really hard to get a game. But Wakefield gave me the opportunity and I played quite a few games for them which was great.
"I came back and feel like I’ve slotted well back into the Huddersfield side. But I know it’s constantly changing - there's Ash Golding who's playing well on the wing as well - so I have to stay performing."
Struggling Trinity, meanwhile, welcome back prop David Fifita as they aim to avoid a fifth straight loss.
