In January 2016, Phil calls Peggy's older sister Sal (Anna Karen) and wants to knoe Louise's (now played by Tilly Keeper) address. When he soon goes to visit at her house, Peggy is there, having returned a week earlier. Peggy is disgusted to see that Phil has returned to alcoholism, but does give him Louise's address. She then reveals her breast cancer has returned, and she is dying. Phil tries to admit that he has cirrhosis of the liver, but she refuses to see him again and he leaves. In May, Peggy turns up on Ronnie's doorstep, and the next day Sal arrives with the news that Peggy's chemotherapy is not working and she is dying. A hospital appointment confirms that Peggy's cancer has spread to her brain and it is terminal. Peggy finally faces Phil, who is in recovery from his alcoholism, and admits she is dying. He is upset that she is refusing any more treatment, and takes her on a boat trip on the Thames, and back to their childhood home, to try to make her fight. However, Peggy is not convinced and asks Phil to help her die.
