Watch the trailer for ‘Gavin & Stacey: The Finale’

The trailer for the final episode of Gavin and Stacey was released on Saturday night.

The last fans saw of Nessa and Smithy, played by James Corden, was in the 2019 Christmas special, where Nessa went down on one knee, asking Smithy to marry her.

The trailer did not make it clear whether the couple has since tied the knot.

But one of the show’s biggest mysteries – what happened during Uncle Bryn and Jason’s fishing trip – may finally be revealed in the show’s Christmas special.
