He receives shocking news: due to Klinefelter’s syndrome, he cannot have children, which deeply shakes his understanding of his family and relationships. The situation escalates when the pregnant stranger, now with her baby, visits the Allens’ home to thank Frank. She inadvertently confirms the misunderstanding, revealing that Frank is not the father. The revelation lands heavily on Frank as he navigates the emotional turmoil of realizing that he has been the faithful partner all along and grappling with the knowledge that the child he thought was his is not.
