Gavin and Stacey return from honeymoon to be greeted at the airport with Gavin's parents waving a banner which embarrasses Mick and Pam recalling her dreadful holiday in Corfu. The two families end up at the Shipmans, where Smithy is angry that Gavin never rang him whilst on honeymoon and Stacey is perturbed that Nessa has not told Smithy of her pregnancy. However, at the local Italian restaurant, where Dawn and Pete are coming to terms with a failed threesome, Pam and Gwen overhear Stacey urging Nessa to come clean. Eventually everybody ends up in the toilet except Bryn and Smithy, who is the last to hear the news.
