Elsewhere, preparations are underway for Alan and Celia’s big day. Celia focuses on the more traditional aspects of a wedding ceremony, whereas Alan has Stag and Hen dos on his mind!

A few days later, Caroline’s back at school when she hears Kate has been rushed to hospital because of complications. Caroline drops everything to be there for her. She walks into the maternity clinic to find a nervous and anxious Kate in the waiting room – has she lost the baby?

Later that evening, Caroline’s having dinner with Alan, Celia and Lawrence. She’s doing a good job of looking cheerful even though we sense the ongoing stress in her personal life. Alan’s telling everyone how his brother, Ted, has hurt his leg so is unable to fly over for the wedding. Just then, the doorbells rings, Alan goes to investigate and it’s Ted (played by Timothy West)! He’s flown over to surprise Alan. The other family members couldn’t make it, but he wanted to be there. Everyone’s delighted.

Finally, it’s the day of the wedding and celebrations are in full swing. Celia looks beautiful and the speeches are full of warmth and laughter. But with emotions running high between Caroline and Kate, and Gillian eager to make a move with Robbie, will everything go off without a hitch?
