Sasha ~ "You're still the same. And that is good. I don't think I can be. Not anymore... Not anymore".

Sasha and her older brother, Tyreese, both lived somewhere in Jacksonville, Florida before the outbreak began. They had a neighbor called Jerry. As children, Sasha used to follow Tyreese around and copy everything he did. When she grew up, Sasha was employed as a firefighter.

During the outbreak's onset, she and her older brother, Tyreese stayed at a bunker in their neighbor Jerry's backyard for about 7 months, until they ran out of supplies. After that, they met up with Allen, Donna, and Ben and joined a larger group, which had about 25 survivors at one point. The camp was eventually overrun, and many were killed. For about 6 weeks they wandered until they arrived at the prison.

Sasha commands authority and likes to be in charge. This is shown after Carl leads the group out of the prison's boiler room. While Tyreese was shown to be grateful for finding a secure residence, she panics about being locked out and yells at Carl and Hershel to allow them into the cell-block after Carl locked the cell-block door due to not knowing if their group was dangerous or not. She is the co-leader of one of the runs the group goes on, along with Daryl. Bob asks for her permission to come along and she is shown to be giving everyone else orders. Tyreese jokingly asks "Was there ever a time you weren't the boss of me?". On the road with Maggie and Bob, she insists they follow her lead and find a place to live by themselves, and strongly suspects their destination to be false hope, which proves to be true. Sasha appears to be a realist.
