"I just double parked him in, he can't leave," Daniher smirked as his coach watched on.
"He's a bit surprised I signed; I was very clever, I went around his back ... and got the deal done before Fages had the chance to agree to it."
While a playful nod to Fagan's insistence his keeps his nose out of list management decisions, the no-fuss announcement was also a big reason why Daniher agreed to lock in his AFL future at the Lions until 2025.
The 27-year-old has found fitness, form and welcome solitude after his final three seasons at Essendon yielded just 15 AFL games.
The Brisbane experience has proved to be a far cry from his high-profile existence and eventual move from Melbourne last year.
"It's been a beautiful change for myself," he said.
"Keeping a low profile in Brisbane; it is a rugby (league) state, but the football side of things is growing significantly and as long as the Lions keep winning we'll keep growing that base.
"It's (the anonymity) is something I enjoy, but it's all part of playing AFL football, dealing with those things. Some people enjoy it, some people don't.
"(This contract) will take me to a point in my career where it'll be pretty much the end, if not close to it. So now I can really just concentrate on football."
Daniher's smooth transition helped convince the Lions' top brass an extension was a good idea, the tall forward becoming the first man to kick a goal in every home-and-away game since the last time he did it in a prolific 2017 season.
The wheels fell off after that, but after playing every game in 2021 Daniher's hopeful those injury-hit final seasons in Melbourne mean his best is still to come in a squad chasing a flag.
He's particularly keen to resume his partnership with fellow tall forward Eric Hipwood, who is eyeing an early-season return from an ACL tear.
"People forget he's still quite young," Daniher said of the 24-year-old.
"Twelve months might be a really good reset for him ... we'll be a better football team with Eric in it."
