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. Written by don @ minifie-1

Annoyed that he was the last to find out about Nessa's situation Smithy disappears. His sister Rudi has no idea where he is but eventually Gavin tracks him down at a golf driving range and brings him home to face Nessa. However, whilst Smithy is prepared to do the decent thing and stand by Nessa, she makes it clear that she has no wish for him to see the baby. Gwen suggests that Nessa moves into Stacey's old room but Stacey, already feeling home-sick, sees this as a severance of her links with Barry and is not impressed to find that Gwen has brought a lorry-load of her belongings to Billericay.

Unable to get a job in Essex and missing Gavin whilst he is at work Stacey is only to happy to pay a visit to Barry with him and Smithy for Nessa's baby scan. Nessa herself, rehearsing for the karaoke competition with Bryn, shows every likelihood of getting back with her old flame Dave Coaches, who runs the local travel service. Smithy stays with Bryn, who indulges in some homo-erotic gym exercises with him, stripped to the waist, which rather shocks Gavin. Then he goes to the hospital with Nessa for the scan but they make it clear to the nurse that they are not a couple. Written by don @ minifie-1

Mick is interviewed on the television news after finding a corpse in a car park, which is the cause for a small celebration at the Shipmans, even though Dawn and Pete argue as usual. Stacey, however, still unemployed, is not in party mood and only to glad to pay another visit back to Barry with Gavin and Smithy. At least this time Nessa and Smithy are civil to each other, she even asking about his girl-friend - whom nobody has ever seen. Indeed after Nessa has impressed Smithy with her perfect strikes at the bowling alley they go home to indulge in a bucket of K.F.C, where corn-on-the-cob takes on a new erotic meaning.
