Seventeen years after Gavin & Stacey begun, the series comes to an end with a 90-minute finale. 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. The BBC's Colin Paterson went behind the scenes during the filming of the last episode.
