Yorkie was paralyzed in a car wreck at 21 after her parents reacted negatively to her coming out as a lesbian. She hopes to get married so that her spouse can authorize her physician-assisted suicide, so she can move on to San Junipero. Kelly lost her daughter at a young age. She visits San Junipero but she doesn’t want to stay because her daughter died before she could go to San Junipero, and her husband chose to die without it as well. [spoiler alert] They fall in love, get married and live out their life in San Junipero.
