Wayne Bennett won't reveal what he thinks has sparked South Sydney's remarkable 14-1 NRL run since they were flogged by Penrith in May.
"I'm not ready to talk about that yet; maybe (next week) but probably not," Bennett said smirking after his side's preliminary final defeat of Manly.
"That was a long time ago ... you should see what we've done since then."
The obvious assumption is that the master coach, entering a 10th grand final and chasing an eighth NRL title with a third different club on Sunday, is keeping his cards close to his chest.
But 36-year-old playmaker Benji Marshall, who's made the most of Bennett's career lifeline as a key piece off the bench this season, isn't so sure that's the case.
"I don't think Wayne knows; that's the beauty about," Marshall said with a grin.
"He pretends he knows, but he's got no idea."
The 56-12 round 11 hiding in Dubbo followed a 50-0 loss to Melbourne a fortnight earlier, signalling alarm bells at Redfern after three previous trips to the preliminary final had ended in defeat.
Their only loss since the Panthers hammering was to the same team in round 23, but they reversed that result in week one of the finals to set up an intriguing decider.
No team has ever won an NRL title after conceding 50 points in a game that season but with that form surge front of mind the Rabbitohs can ruin that statistic in Sunday's rematch at Suncorp Stadium.
"We can't win, we've lost by 50 points twice," Marshall told reporters when asked what gives him hope.
"But you've got to have that belief in your side and the way we've played, especially defensively, in the last 10 weeks we were up in the top two teams there defensively.
"So that gives you confidence, but if you look around our side we have guys like Cody Walker, (Blake) Taaffe, (Adam) Reynolds who can do the damage.
"But there's also unsung heroes like (Tevita) Tatola, Mark Nicholls, (Damien) Cook through the middle.
"They don't get a lot of wraps, but when you've got a 17-man squad willing to do whatever it takes, that's pretty powerful."
An NRL title winner with Wests Tigers in 2005, Marshall credited Bennett for "saving his career two times" - by recruiting him to Brisbane in 2017 and then Souths for this year.
A return to the grand final will be 16 years in the making for Marshall in one of many feel-good tales to be told in the week ahead.
But Marshall, who vigorously hugged Bennett in the sheds after the win over the Sea Eagles, hesitated to confirm it will be his final NRL game despite the coach all but doing it for him on Friday night.
