Nothing is known about Sophie's life prior to or as the outbreak began. She may have found or was going to school at Ericson's Boarding School.
About a year before the events of "Done Running" Marlon traded her along with her sister Minerva away to a group of raiders, know as Delta, during a supply run. According to Violet, she was an artsy person, often partaking in activities like painting.
Tenn is Sophie's younger brother. Tenn wasn't sad about her 'death' believing she is happy in heaven. After knowing that his sisters could still be alive, he stays positive and can be seen talking to AJ about Sophie and Minerva could be with the raiders when they come.
They're twin sisters. According to Tennessee and Violet, the two spend a lot of time together.
This list shows the victims Sophie has killed:
- Possibly numerous counts of zombies and unnamed people
- "Done Running" (Photograph)
- Sophie and Minerva are the first twins to be mentioned in the game.
- Sophie and Tennessee are probably half-siblings given that she and her sisters are Caucasian and he is African-American. This could simply be an oversight though.
