She later regrets that decision. Jack’s condition eventually becomes much worse. Claire stays beside him during his final days. He tells her that she looks frightened.

Claire says that she does not know how. Jack tells her that she will figure it out. Those become his last clear words. Three days later, Jack dies.

Claire is left pregnant, grieving, and responsible for Lucy. She also faces serious financial problems. The funeral creates another bill. The mortgage is threatened by an existing loan. Claire has already spent their savings on Jack’s treatment. She has even sold her jewelry. A bank employee tells her that there is not enough money to cover the following month. Claire explains that she borrowed against the house because she wanted to give Jack another chance. She realizes that hope does not disappear when the bills arrive. A week after the funeral, Claire returns to the hospital for Jack’s belongings. A nurse named Rachel gives her a bag containing his personal items. The bag includes his watch. It contains his charger. It contains toiletries. It also contains a paperback book. Then Claire notices a gray women’s cardigan. She knows that the cardigan is not hers. Rachel explains that she thought it belonged to a woman who visited Jack. Claire immediately becomes suspicious. Rachel says that the woman visited several times. She describes her as a dark-haired woman in her early forties. Claire asks whether the woman and Jack argued. Rachel says that she never saw them argue. Claire learns that papers were often spread around while they talked. Claire remembers the papers Jack had hidden. She eventually views security footage. The footage confirms that the mysterious woman visited Jack repeatedly. Claire sees the woman carrying a folder. She also sees the woman crying during one visit. Claire begins wondering whether Jack was unfaithful. She asks herself whether the secret involved another relationship. Three days later, someone knocks on her door. The mysterious woman is standing outside. She introduces herself as Mara. Mara says that Jack asked her to deliver an envelope after his death. Claire demands to know why she visited Jack. Mara says that Jack wanted Claire to receive the envelope only after he died. Claire opens it. The letter is written in Jack’s handwriting. Jack apologizes for Claire learning the truth without him. He tells her about a five-year-old boy named Ethan. Jack says that Claire does not owe Ethan anything. He tells her that she can stop looking if she wants. He nevertheless asks her to find Ethan. Claire becomes frightened and confused. Mara refuses to explain exactly who Ethan is. Claire suspects that Ethan might be Jack’s secret son. Mara denies having an affair with Jack. She explains that she knew him from a children’s home. Mara now works with children and families in the care system. She had been helping Jack locate Ethan. She says Jack did not want to place another responsibility on Claire while she was pregnant and caring for him. Claire remains convinced that Ethan is Jack’s son. After Mara leaves, Claire searches Jack’s laptop. She discovers that Jack changed the password. She eventually realizes that he used the date they met. Claire finds repeated references to Ethan. She discovers legal expenses and childcare costs. She also finds something called the Ethan Trust. She realizes that Jack had been protecting money for the boy. Claire also finds insurance documents protecting herself and her children. She discovers maps leading to the same address. She calls Mara and announces that she is going there. Mara warns her not to arrive angry. Claire insists that she wants the truth. She drives to the address believing she is about to meet Jack’s hidden son. A foster mother named Denise answers the door. Denise confirms that Jack visited Ethan. Claire meets the little boy. Ethan has dark eyes and a stubborn cowlick. Claire immediately thinks he looks like Jack. Ethan recognizes Claire because Jack showed him photographs. Ethan knows about Lucy and Claire’s Sunday pancakes. Claire realizes that Jack had talked about his family with Ethan. Denise explains that Jack visited Ethan several times. Claire asks whether Jack was Ethan’s father. Denise says she honestly does not know. Claire then contacts Mrs. Bennett, an older woman who had also been connected to Ethan. Mrs. Bennett reveals an old photograph showing Jack with another boy named Daniel. She explains that Daniel was Jack’s brother. Claire is shocked because Jack believed he had no family. Jack and Daniel had entered care after their parents died in an accident. Errors in the system separated the brothers. Jack eventually discovered Daniel’s existence. By then, Daniel had already died. Daniel, however, had left behind a son named Ethan. Claire finally understands why Jack could not walk away from Ethan. He had finally found his lost brother only after his brother was gone. Ethan represented the family Jack thought he had lost forever. Mara later returns to Claire’s home. Claire asks why Jack kept everything secret. Mara explains that Jack knew Claire would immediately try to help Ethan. He knew she would accept another responsibility without considering whether she could afford it. Jack wanted Claire to have a genuine choice. Claire realizes that his secrecy was misguided but understandable. She also learns that some of Ethan’s trust came from Daniel’s estate. Jack had also protected Claire and their daughters financially. Claire laughs sadly because Jack had even made spreadsheets for his plans. She realizes that he knew she would investigate everything after his death. Claire remains unwilling to pretend that Jack handled everything perfectly. She still understands why he made his choice. She contacts Ethan’s caseworker. She meets with Denise. She speaks with an attorney. She learns that guardianship will require careful consideration. Claire admits that she cannot currently afford another child. The attorney is pleased that she is thinking realistically instead of making an impulsive promise. Claire begins allowing Ethan to visit regularly. She is still unsure what their future family will look like. She no longer feels compelled to control every outcome. Claire visits Jack’s grave. She places the photograph of Jack and Daniel against the gravestone. She tells Jack that he found his brother too late. She tells him that he still found Ethan. Her unborn daughter kicks as she rests a hand on her stomach. Claire says that she will handle the situation her own way. She understands that Jack did not leave her an obligation. He left her a choice. The guardianship process continues. Ethan becomes a regular part of their lives. Claire accepts that she cannot bring Jack or Daniel back. She can, however, help keep their remaining family connected. She realizes that this may be the way she prevents Jack’s family from being lost twice.
