Finding Hilary later, Mel and Greg demand an explanation so Ashley (John Middleton) drops a bombshell by revealing that Daniel and Arthur may have been swapped at birth. Laurel (Charlotte Bellamy) is furious with her husband's gall as Mel breaks down in distress. Greg tells the Thomases to get out as the Dolands struggle to deal with the heartbreaking news.

With no other choice, Zak makes Belle apologise to his boss. Will that be enough to save his job?
