After all, the Scarlets went to Glasgow and produced a blistering display in the semi-final two years ago at Scotstoun, while last year it was the Warriors who exacted a measure of revenge.
Their Round 10 meeting was a thrilling affair, with Glasgow overcoming an early red card to get the better of their visitors.
It was quite remarkable considering Alex Allan was given his marching orders after just 18 minutes for a no-arms tackle on Jake Ball.
But with fly-half Brandon Thomson pulling the strings – as he likely will do again tomorrow night – the Warriors were able to open up a sizable lead, and eventually hang on for a 29-20 victory.
Thomson had got the ball rolling with the opening try, stretching over the line after the forwards had done the hard work in close.
That allowed Glasgow to take a 13-3 lead into the break, and they flew out of the blocks in the second half when Nick Grigg took advantage of Jonathan Davies fumbling the ball while chasing back. The Scotland centre then pinned back his ears to race over, and at 20-3, the Scarlets looked out of it.
They roared back though, Davies powering through the tackle of Ruaridh Jackson for their first try.
Glasgow were still in control however, particularly after two further penalties pushed the lead back to 18 points, but just as they looked set to score another, Davies picked off a pass from Nick Frisby and raced away.
He didn’t quite have the pace to go all the way, but the ball was spread from right to left allowing Steff Evans to go over in the corner.
And when Clayton Blommetjies, who had delivered the final pass to Evans, finished off a Rhys Patchell break, the Scarlets could start dreaming of a win and possibly even maximum points.
Instead, the Warriors saw out the final six minutes, still a man down, and a fifth Thomson penalty even denied the Scarlets a losing bonus point from their trip to Scotland.
After beginning their season with a home win over Connacht, Brad Mooar’s team will be dreaming of more than just a losing bonus point this time around.
