But how will Sophie feel about the bond that's starting to form?
Ryan’s devastated when he receives the news that he’s not a match for Oscar. As Marlon comforts a crushed Ryan, the relief is palpable when a frantic Gail rushes in to announce that, against all the odds, she and Oscar are a match.
The following day, Gail prepares to see Oscar ahead of the surgery but Ryan worries about meeting his son for the first time.
At the hospital, Gail and Oscar get on famously, whilst an awkward Ryan hangs back feeling the odd one out. When the conversation turns to music, relieved Ryan finds a way in. Watching on, Sophie is conflicted about the bond that is starting to form.
Back at the Woolpack, Marlon reminds Gail to tread carefully around Oscar’s adoptive mother and the importance of tomorrow starts to dawn on them.
The next day, a nervous Ryan supports Gail as he sees her off into surgery and they're both hopeful that they can now be a part of Oscar’s life.
