It's moving rapidly from the sublime towards the utterly ridiculous.
And assuming Rangers finish off the job in Belgrade on Thursday night then this European adventure will have entered into a truly surreal state of affairs.
Let’s be blunt here. UEFA have not designed their tournaments in order for teams from this part of the world to get anywhere near the latter stages, never mind gain entry into the VIP room that is the last eight.
But that’s exactly where Giovanni van Bronckhorst and his players appear to be heading, having already planted one boot in the next round with Thursday night’s thrilling three-goal routing of Red Star at Ibrox.
Logic dictates that it will come to an end and probably sooner rather than later.
But then Rangers removed common sense and sound reason from the equation when they eliminated favourites Borussia Dortmund from the knockout stages.
And the manner with which they set about the Serbian champions last week did little to dampen the notion that something extraordinary might be happening before our very eyes.
They carried the feel-good factor all the way up to Tayside yesterday afternoon when they did away with Dundee at Dens Park to join Hearts and Hibs in the Scottish Cup semi-finals.
But it’s the continental surge which really lights up the imagination and bends the boundaries of what really ought not to be possible.
Yes, one look at the rest of the teams jostling for a place in the quarter-finals might help to keep expectations in their place.
Just the very mention of the likes of Leverkusen and Lyon ought to be enough to restore some sense of reality given that both of those heavyweights have roughed Rangers up on their own pitch over the last couple of years.
And that’s before the likes of Barcelona, West Ham and serial winners of this competition, Sevilla, are factored into the equation.
That list alone tells you that Scotland’s champions should be winding in their necks at this level. Yet it’s becoming harder and harder not to suspect that something bordering on the historic just might be brewing on Glasgow’s south side.
It just has that fatalistic feel to it, almost as if the stars are starting to align.
It happened to Celtic back in 2003 when they made it all the way to the final in Seville and, at the time, it too felt like something special was on the cards for Martin O’Neill and his players.
In fact, for those of us fortunate enough to have reported on that run, it felt like a once-in-a-lifetime achievement given that the days of watching one of our clubs trading blows against Europe’s best and competing with them for silverware seemed like they had gone for the rest of time.
But, five years later, Walter Smith managed to work a miracle of his own by leading a stubborn Rangers team way beyond its limitations and all the way to a final of their own in Manchester, despite being branded as ‘anti football’ earlier in the season by none other than Lionel Messi.
Smith was proud of that one. ‘He was right, we were anti football’, Smith used to grin with considerable satisfaction and understandably so given the way he managed to mould together a team that was way bigger and better than the sum of its parts.
But while that Rangers side bored their way through the pack before knocking out Fiorentina on penalty kicks in Florence in a thrilling finale to the second leg of the semi, this current lot are going about their business with an outrageous, free flowing sense of flamboyance by comparison.
Where Smith’s team could be a hard watch, Van Bronckhorst’s side is rapidly becoming a must watch on these Thursday night specials.
The beating they dished out to Dortmund over two legs was true box office stuff.
But to follow that up by unleashing 50 shades of mayhem during Thursday night’s romp over Red Star?
That really was a mind altering display and it’s performances like that – when nothing appears to make any sense at all – which cause perceived logic to be called into question.
So, yes, it does feel as if Rangers might have some miles left in the tank ahead of the return trip to Belgrade this week, even if it would be a mistake to go there thinking all the heavy lifting has already been done.
That the Serbs had the ball in the back of Allan McGregor’s net on three separate occasions – only to have each of them wiped out by a linesman’s flag – is all the reminder needed of the threat which Red Star still carry into Thursday’s second leg.
Should the home side score first and score early then the situation will suddenly become a great deal more complicated and nervy than it seemed when the final whistle sounded last Thursday.
But, even so, there is an energy and exuberance about the way in which Rangers are handling these ties which evokes confidence.
In fact, they might even be better equipped for playing away from home, such is the speed and power with which they can hit opponents on the break.
It was all too much for Dundee as the Light Blues picked up where they left off in midweek.
And that emphatic return to domestic duties – coupled with a sighting of the lesser spotted Aaron Ramsey – also suggests that Rangers might finally be finding some momentum at a critical moment in the season.
They’ve coughed and spluttered along the way and often struggled to replicate their European performances back on home soil.
But now that they find themselves motoring so close to a place in history, it would seem unwise to be writing anything off just yet.
