This episode features twins Jennifer and Kathleen, who spent over 60 years apart before the search discovered that they were living just three miles from each other in Rotherham. Four years on, and after a lifetime of nearly crossing paths, has the bond they had as babies survived the years they have been separated?
The show also catches up with Polly and Steve, a mother and son who had been apart for over 50 years before Steve was tracked down in New Zealand. A year on from their reunion, and with 12,000 miles between them, how easy has it been to build a bond as mother and son?
Finally, Laura and her sister Alison were reunited after the programme discovered that Laura's mother had passed away. Laura was desperate to find a blood relative to help her to understand her identity, but has a reunion with her sister given her the answers that she was craving?
