- "Hold your horses, Clem! Sorry. There's something in the treehouse, and she wants me to get a video of it to show you guys."
- —Sandra while videotaping Clementine for her parents. (Draw-Time Scene)[src]
Not very much is known about Sandra's life. She was likely a paid babysitter for Clementine. She was asked by Clementine's parents, Diana and Ed, to look after their daughter while the two were on vacation in Savannah, but promised to be back before her spring break. During her parents' absence, and Sandra being her caretaker, the two discovered a raccoon up on the tree-house. Clementine asked Sandra to tape her interaction with it, as Clementine's parents call. In the conversation, Diana tells Clementine to be nice to Sandra, while Ed tells her not to get his hat dirty and that he let Clementine borrow it. After that conversation, Clementine says that she is looking forward to see both of her parents to come home.
Before the outbreak, Clementine spots a raccoon in the tree house. Sandra comes rushing out of the door with a camera to video tape the raccoon. This raccoon is thought to be the same raccoon in Season 2, Episode 4.
Sandra might have been hiding with Clementine in the treehouse for a few days before the former's untimely demise. At one point, Sandra left the treehouse to possibly seek help, use the phone or watch the news (which would explain why the television was on when Lee entered the house). It is implied that Sandra was attacked by a zombie two days before Lee Everett arrived at Clementine's house. When Lee enters the house and looks around, he spots a pool of blood likely from Sandra and then hears Clementine on a walkie-talkie. When Lee slips in the pool of blood, Sandra crawls for him. Clementine arrives at the sliding glass door and hands Lee a hammer which he then uses to kill her.
Sandra is briefly mentioned by Clementine when she tells Luke how her parents left her with a babysitter.
Sandra is determinately mentioned when Jane is talking about her sister, Jaime. Clementine then says that she would pretend that her and Sandra were "secret sisters". (Determinant)
- Zombies (Alive)
Clementine says she heard Sandra screaming a few days before Lee Everett got to her house and then reanimated soon after. It can be implied that she was attacked by walkers.
Lee Everett slips in her pool of blood and she crawls after him. Clementine walks to the sliding glass door, opens it and gives Lee Everett a hammer. He then proceeds to beat her on the head with it repeatedly and kills her.
- "A New Day" (Zombified)
- "No Going Back" (Draw-Time Scene)
- It takes only three hammer blows to incapacitate a zombified Sandra, but adding a fourth blow will reveal a rather gruesome scene.
- The scene where Sandra films the raccoon in Clementine's treehouse is only in the trailer for "No Going Back".
