We Are the Brennans

After her father leaves, Grail tells Kale and the three Brennan siblings that Billy Walsh’s time of death clears all of them of the murder. She also says that a detective in Belfast told the West Manor police that Billy angered a drug cartel in Belfast, and they likely killed him. When they ask if the police found the gun, Grail says they have not. Soon after, she leaves. After they discuss who might have taken the gun, Sunday informs Michael Eaton of Billy Walsh’s death and tells him that she is enrolling in a master’s program and writing a few stories, including a children’s book.

Sunday then walks to Hollis Park and sits on one of the benches. There, she remembers the aftermath of the attack. She reveals that even though she wanted to move forward after Kale returned from his Ireland trip, her guilt caused her to push him and her family away. In a flashback, she decides to tell her mother, and her mother reacts horribly to finding out Billy Walsh attacked her. She shames Sunday and tells her not to tell the family because it would disgrace them and Kale. She also tells Sunday that it is only Sunday’s business.
