The emotional TV series – fronted by Davina McCall – revisited families who had been reunited in the past to keep show watchers updated with their stories.
On tonight’s episode, the show followed Vanda and Debbie, Andrew and his parents, as well as Margot and Christine.
The TV series revisited each story to give some background knowledge before documenting how the reunited families were getting on since the show.
First up was Vanda, who reached out to the show to find her brother.

However, in a sweet twist, Vanda discovered that her brother had transitioned into a woman and was now living her life as Debbie.
Vanda was overjoyed by the discovery and said: “I’ve always wanted a sister.
“It really doesn’t matter, it’s just to know that person, no matter what the body is.”
The two sisters have regularly visited each other since their reunion – making plans for their future – and Debbie is even in the process of permanently moving to Vanda’s town.
Next up was Sue and Chris who were looking for their son that they put up for adoption when they were just teenagers.
The trio regularly met up with each other since the reunion – despite the long distance between Canada and England – and their son, Andrew, met his siblings for the first time.

Finally, viewers learned the heartbreaking story behind Christine and Margot.
Christine put Margot in care when she was younger as she wanted a better life for her daughter.
However, when Christine was told a few years later that Margot’s foster mother had died, the guest made the agonising decision to keep her daughter in care so she could stay with her foster father.
But sadly, Margot’s foster father died shortly after and the orphaned youngster was put into a home.
She admitted: “That was scary.
“I had noboby, nobody in the world.”

However, upon reunion with her mother, Christine, the two have become inseparable and they call each other every night.
While Christine has not only been reunited with her daughter, but with her grandchild and great-grandchildren too.
The show ended with Margot and her family celebrating Christine’s birthday for the first time since their reunion.
Viewers were left in tears over the heartbreaking scenes and took to Twitter to share their thoughts.
