After the euphoria of Saturday's win over Hull City, Swansea City were brought down to earth with an almighty bump at the hands of Leeds United on Tuesday.
Here are the key talking points to emerge from the 4-0 defeat at the Swansea.com Stadium.
Swansea's biggest issue exposed
Tuesday night's contest, if we're being honest, was all over after about 10 minutes.
The ease in which the Swans defence were exposed for Joel Piroe's strike to make it 2-0 certainly made it hard for even the most optimistic member of the Jack Army to map a way back into this game.

Indeed, had Leeds hit double figures heading into the break, few could have really complained.
It's becoming an all too familiar feeling lately. In total, Swansea have conceded 13 first-half goals in their last six games in all competitions. They've gone on to lose five of them.
Clearly there's a problem with conceding early goals, and that's a real issue when coming up against the Leeds Uniteds and Southamptons of this world.
Williams mirrors Martin
When he was still MK Dons boss, Russell Martin infamously hit out at suggestions his side needed a Plan B, instead insisting that the best course of action was to simply polish and perfect Plan A.
The clip went viral, and encapsulated the spirit and philosophy so many Swans fans came to admire during his time here. Reading between the lines, his former colleague clearly has similar views.
Williams is certainly likely to be scrutinised for his approach to this game in a similar way. Swansea's high line, particularly in the first half, was opened up and exploited time and time again by a Leeds side oozing with attacking talent. Some would argue it was all far too naive, but it seems unlikely that we'll see any radical changes under the current boss, who feels it's the application of the idea, rather than the idea itself that needs work.
"We have to play in a certain way week in, week out and we have to practice to get excellent at that so we don't have one week where we're going to be really deep and try to play on the counter and the next week try and dominate the ball and press," he said.
"We have to start to learn a style of football we're going to play and we're going to commit to so we can practice that style and become very, very good at it. Unfortunately without putting in the time and the effort we're not going to get there.
"So we have to be brave enough to try against the opposition. We've conceded goals early, particularly against the really strong teams, but we have to try and model ourselves on wanting to be top team as well.
"I don't have a problem with the formation or the idea. It's the execution that needs to be better. I want us to play a different high- level model of the game and that requires a lot of hard work and commitment."
Myko under the microscope
The signing of Mykola Kuharevich has come under increased scrutiny in recent weeks, particularly given the Ukrainian's chronic lack of game-time.
Seeing him left on the bench in favour of Jerry Yates clearly sparked a fair bit of head-scratching on Tuesday, and many are understandably wondering where precisely he fits in.
"At some point he's going to get his chance," Williams told WalesOnline recently. "Hopefully he has that little chip on his shoulder and wants to prove everyone wrong. I look forward to that.
"It's difficult because I wasn't in the building before. You have to be careful when you talk to different people about what's happened. You need to try and make your own decision. Of course you listen to the things about what's happened earlier on in the season. But it's unfair. I need to try and judge him myself.
"I've not made a decision on him. I've not ruled him out of anything. Whatever's happened earlier in the season, I've heard thing, but I don't know for sure."
More potential right-back woes
We were all half joking when we hammed up Swansea's right-back troubles as some kind of curse. But now? Well, we're all starting to get a little unnerved.
Things are going on here that can't be fully explained.
Bashir Humphreys, the man tasked with filling in for Kyle Naughton, who was only fit enough to start from the bench on Tuesday following the knock picked up at Hull City, has become the latest concern, after limping off midway through the second half.
Is it really coincidence? In the age of knee-jerk reactionary conspiracy theories, it's a little surprising the darker corners of social media haven't yet concocted some sort wild explanation involving Satanic death cults.
In all seriousness, it is becoming a rather unfortunate trend, particularly in light of such a bruising schedule.
Williams doesn't like to give too much away when it comes to injuries and timelines, which is entirely his prerogative. But Swans fans might well feel a little uneasy about about what now lies in wait for Saturday's clash with Ipswich Town.
"We'll have an assessment for him," said Williams when asked about the Chelsea loanee. "Maybe it's not anything too serious. Kyle Naughton came on tonight and looked good when he came on. So I think we'll be OK, but I think Bashir has a chance to be fine anyway for the weekend."
Makes you think.
Leeds duo pay tribute to fans
Leeds had four former Swans in their matchday squad on Tuesday. Joe Rodon and Piroe started from the off, while Daniel James and Connor Roberts both came off the bench.
There's a chance all of them will be Premier League players by the end of the season, but the mark left by their time in SA1 clearly runs deep.
At full time, and having contributed to hammering their former employers, Rodon and James showed their appreciation to the Jack Army with a lap of the pitch.
"To be fair it was a bit weird," Rodon said afterwards. "I haven't been back here I think since I left. Of course it means a lot to me, it's where I grew up, it's where I came through and I will always have this place in my heart and I'm just looking forward for the future."
