There was only one way to sum up Troy Deeney's emphatic seizure of Watford's FA Cup fate as the last granules in the sand-timer of this game trickled away: Cojones.
Given the responsibility for keeping alive his club's hope of silverware on a dramatic day at Wembley there was no shred of self-doubt.
Deeney struck not so much a spot-kick as a spot-steam train, sending the ball so fast and so hard past John Ruddy that even though the Wolves goalkeeper went the right way he did not have time to get his arms in the way.
The ball whistled past Ruddy's gloves, burst into the back of the net, and the destiny of this most enthralling semi-final was wrested away from Wolves and towards Watford.
It is a year since Deeney created waves by stating Arsenal lacked, how should he say it, cajones when being beaten at Vicarage Road and it is tempting to wonder if that crossed his mind at all as he waited to take his penalty in the fourth minute of stoppage time.
The VAR check caused an extended period for Deeney to contemplate the moment at hand, the weight of history, the opportunity for glory and also horror.
Had he missed you can imagine a few Arsenal players might have had a something to say, certainly privately if not on social media (even if they have shown a propensity in the past for posting dressing-room selfies on Twitter).
But Deeney did not buckle, he walked the walk and wrote another chapter in his emotive story with Watford. He will no doubt revel in taking his particular brand of bullishness up against Manchester City's players in next month's final.
Spare a thought for Matt Doherty though. He has known the worst of times with Wolves and the majority of this contest it appeared he would be to the fore now it seemed the best of times.
Scoring in an FA Cup semi-final at Wembley must have seemed a remote possibility five years ago as Doherty was playing at Colchester and Port Vale off the back of a relegation to League One that had seen toxicity spread across the terraces.
His header nine minutes before the break opened the scoring, and his cross shortly after the hour set up Raul Jimenez to open up a cushion. It turned out that once Deeney removed the cushion there was a heavy landing.
At the final whistle, when Gerard Deulofeu's magical goals had swept Watford to victory, Doherty collapsed to the ground, spent physically and emotionally.
Nine years ago Doherty left Dublin to sign for Wolves in a £75,000 deal that already represents magnificent business.
He would dearly have loved to enhance that value with another day at Wembley and the chance of Wolves gaining silverware for the first time since the 1980 League Cup.
It is instead Watford who have that opportunity, and with Deeney leading the way - wearing the armband like a superhero's cape - City's quest for a Quadruple certainly won't come easily.
