As S4C's pitchside reporter collared man of the match Sam Costelow pitchside after the Scarlets' dramatic Challenge Cup quarter-final win over Clermont, the expression of the young fly-half, with blood strewn down the one side of his face, was a mixture of jubilation and exhaustion.
But when Lauren Jenkins launched into a Welsh language opening question about what had been going through his mind ahead of his crucial match-winning conversion, that expression quickly turned to one of horror.
"Sorry, I don't speak Welsh," he quickly spurted out.
Thankfully, such panic wasn't etched across his face as he lined up the pressure-filled conversion from near the touchline after Ryan Conbeer's contortion act had seen the wing sneak over for the score-levelling try.
Post-match, Johnny Williams admitted that, far away from the tee, he was feeling the pressure. So you can only imagine what was going through Costelow's head.
Still, his eyebrows weren't as raised as when hit with a question in Welsh. Frankly, the momentary terror belied his ability to solve problems on the field.
There's always been a touch of the X-factor about Costelow. Even at age-grade level, the fly-half was reliable for producing the sort of highlight reel moment that could easily go viral on social media.
His ability to break a game has always been apparent, such as when he turned bad ball into a stunning score against England U20s in 2020 thanks to his low-centre of gravity and knack of stepping past people with ease.
That's carried on with the Scarlets, where he continues to offer the spark in the west Walians' backline. He's crucial to their attacking shape, with his own running threat only heightening what the Scarlets can do with ball in hand.
He's seemingly at ease with reading situations and, more often than not, finding a decent - often eye-catching solution - to it.
But to reduce him down to a highlights player is to do the 22-year-old a disservice. Because, above all, he's got a proper grit to him.
The conversion showed that. His coach, Dwayne Peel, called it a "huge kick" in the aftermath before stressing that there's still things for Costelow to work on.
"When you look at his game in general, he himself would say he wasn't man-of-the-match," he said. "There were a couple of kicks there that he probably could have executed a bit better.
"But he's growing every week, he is developing into a leader here. To kick that at the end was huge because I know how hard he works at that aspect of his game."
Then there is Costelow's effort in defence. He's not the sort of fly-half coaches would feel the need to hide out on the wing - instead, he approaches tackles with relish.
If the Scarlets under Peel are trying to forge an identity of working hard for one another in defence - and the second-half of Clermont certainly showed that to be the case - then Costelow's willingness to scythe down men much bigger than him is testament to that.
He's a classy player, but he's tough as teak. In American sporting parlance, he's got that dog in him.
Having been eased in at Parc y Scarlets to temper expectations, he's now the main man in Llanelli. That resulted in him being capped last autumn against New Zealand and Georgia by Wayne Pivac.
Warren Gatland opted not to call him up for the Six Nations, raising doubt over whether he'll feature at this year's World Cup. Regardless of whether Gatland fancies taking him to France, you'd still wager that he's the future of the Welsh 10 jersey.
And not being in Wales' Six Nations squad has done little to hinder his progress. Since the end of November, Costelow has started 10 of the Scarlets' 13 games - only serving to establish himself as the Scarlets' first-choice.
Crucially, at a time when the fly-half situation in Wales is creeping towards carousel territory, with the likes of Jarrod Evans, Rhys Priestland, Gareth Anscombe, Sam Davies and Rhys Patchell all seemingly likely to move this summer, Costelow's fate is secure.
He's Peel's first-choice in Llanelli. That's as much for his tough, scrappy determination as it is the moments that will attract the likes on social media.
And, of course, for showing nerves of steel.
