Sasha's home life was pretty hectic. Divorced parents, with an abusive mother and a non-responsive younger brother. School life was better, but not by much, as she's too shy to interact with other students. She does find some solace among the teachers, but because of their inherent authority over her, she can't really forge a friendly relationship as if she would with another student. The one person who she truly likes being around with as much as he does is her mentally-ill twin brother, Elliot, whose illness alienates him from the student body. This does not bode well for Sasha, who has been described as being similar to him on multiple occasions. Thus she becomes more withdrawn, overthinking everything she might say by holding mental conversations with herself, as an attempt to prevent alienating herself from people because unlike Elliot, Sasha secretly wants to be around people who she can completely trust.

When apocalypse hit, she was preparing for post-secondary education along with Elliot. When her and her family found out in the news that zombies have become rampant, disagreements were all over the place about how to deal with the situation, which culminated into Elliot running away in the night to places unknown, leaving a note and backpack full of starter supplies for Sasha to do the same. Alone and confused, Sasha decides to run to the only place she thinks she could go: St. Walkers, the place where she had just graduated from.

Personality wise, Sasha is intelligent, but introverted. She doesn't like talking to other people which gives people the impression that she's antisocial. She's observant of her surroundings, and puts much thought into her words as she has mental conversations with herself. Outside, she's cold and stoic, inside, conflicted. What most people don't know is that she can be rather eccentric. Her slight facial expressions are key to generalizing what's going on in her mind.
