- "That vase - that's something special. 'Fess up. You steal that from your Grandma Jean's house? I hope you left her that spoon collection."
- —Rick to Shane[src]
Almost nothing is known about Jean's life before or as the outbreak began other than that she is Shane's grandmother.
As Rick was waking up from his coma, he was hallucinating that Shane was in the hospital room and mentioned Jean while commenting on the flower vase set in his room, jokingly asking if he stole it from his grandmother Jean's house.
It is unknown what happened to Jean after the apocalypse began, leaving her with an unknown fate.
