With just six weeks to go until the wedding, the nerves and excitement are beginning to show. Gavin has a very important question for Smithy, while Nessa is having uncharacteristic doubts about herself. Meanwhile the Shipman family and friends travel to Barry for a wedding fair. The event exceeds all expectations, with Smithy completely mesmerised by Jammy the ultimate stag do organiser (guest star Matt Lucas), and Bryn totally sold on a magician for the wedding.
