Abigail’s mother Lynn is loud and larger-than-life, and her appearances at the Salmon household, though rare, are always fraught. Though outlandish, superficial, and slightly self-absorbed, Grandma Lynn cares deeply for her daughter, Jack, Lindsey, and Buckley, and does all she can to help them put their lives back together in the wake of Susie’s death. Grandma Lynn senses that her daughter is having an affair, but is ultimately powerless to shake Abigail out of it. Once Abigail leaves for California, Grandma Lynn comes to stay, moving into Susie’s old room and taking on the role of the Salmon family matriarch in her daughter’s absence.
