Leo learned he was adopted by accident shortly after he began dating Emma. He was looking for childhood pictures when he came across his adoption paperwork. He confronted his parents and learned his biological mother had died, removing any chance he had to meet her.

While at a Tom Jones concert with Leo’s brother and his family—whose children are unruly and undisciplined—Leo confronts Emma on the color of her graduation gown. She says they probably changed the color over the years.

As Emma takes Ruby to have ice cream, she worries that Leo has caught on to her lies. She didn’t graduate from St. Andrew’s University; she had to leave school and decided to finish at the Open University. After she graduated from the Open University, she changed her name to begin life anew. She had planned to tell Leo early in their relationship, but then he discovered his own adoption and was so furious at his parents after learning his biological mother died before he had a chance to meet her that she didn’t believe it was the right time to tell him. Time passed, and it got harder and harder to tell him.
