Peggy admonishes Lilian for Matt's behaviour over Bridge Farm, but Lilian protests that there's nothing she can do about it. They decide not to discuss it in front of Jack, who is becoming increasingly confused. They all head off to Home Farm to try to take Jennifer's mind off things. Jennifer suggests to Lilian that the way Matt's behaving may be due to jealousy. She thinks it's because he's never had a close family.
At Siobhan's grave, Brian is surprised that Father Dominic recognises Ruairi. He discovers that Bridget and Niamh used to take him to Mass. Afterwards, at the airport, Ruairi is subdued. Brian is concerned.
Lilian and Jennifer research Matt's family, on the internet. Even with limited information, they come up with one match for Matt's grandfather. Excitedly, they imagine how this could change Matt's perception of things. As this discovery leads to other relatives, Lilian starts planning a reunion. When Matt returns, Lilian can't wait to tell him the news but Matt's not impressed. He says finding out about the Crawfords will not help him learn anything about his roots. A deflated Lilian cannot comprehend this. Matt says it's because he was adopted. Now - will she just let it go?
