Gwen, played by Melanie Walters, and Uncle Bryn, played by Rob Brydon, are seen clambering into Bryn's car alongside Gavin, Stacey, and Nessa.
No prizes for guessing where they are heading.
"In Barry, Bryn's packing the Picasso in readiness for a trip to Essex," reads the official synopsis.
Soon enough, Gavin, Stacey, and the rest of their family and friends are seen in high spirits with another get together at Pam and Mick's house.
This time it looks like Bryn will be giving limbo a go.
Clearly, Pam and Mick are playing host this time around, but why are they partying?
"Over in Billericay Pam is stressing out at the prospect of playing hostess, not helped by a newly retired Mick practising his golf swings in the living room and there have been more ups and downs in Pete and Dawn's relationship."
Before the final episode, the last we saw of Nessa and Smithy was in the 2019 Christmas special, where Nessa went down on one knee, asking Smithy to marry her.
Clearly, things have moved on since then, with the finale picking up five years later.
Along with these first-look images, fans can also get a glimpse behind the scenes.
New photos taken during filming show some of our favourite Gavin & Stacey stars on set, with Ruth Jones, as Nessa, getting a quick touch up to her make-up while filming on Trinity Street.
Whether or not he said 'yes' remains to be seen.
Although the upcoming finale will be the last episode of Gavin & Stacey, that doesn't mean their stories won't continue... even if we're not around to see it.
"I think we've always felt like they really do exist," said Jones.
"It's not like they're dying – well, watch the final. But the thing is, we feel like they still exist so for us, they're carrying on living their lives in Barry or Billericay, just we are not party to what goes on in their life any more."
