main canon; beth greene is the 2nd daughter to herschel greene, but the only child between he and his second wife. when the dead rise, his wife and son are both killed by walkers, beth takes their deaths harder than anyone else in the family but with the comforting hand of her sister and patricia she begins to heal slowly. her delicate emotions are barely touched on by her family once rick grimes arrives at the farm after otis had accidentally shot him through a buck he’d been tracking.
beth helped with the boy, and slowly got to know the others - but her father didn’t much like them there, so he forced her to keep her distance. during this time, jimmy was more persistent about their relationship but she had told him time and time again that she didn’t want that with anymore. he was nice enough but he wasn’t what she wanted, she had expected a small summer fling then for them to go their own ways before she began her senior year of high school.
when the barn was opened by shane walsh she’d seen her momma and brother shawn; her heart had shattered into a million pieces. why had they been out there? why didn’t they recognize her. the dose of reality broke her heart and she was unable to cope with the loss of her family, she made a decision and andrea helped her with it by leaving her alone.
but it was wrong she didn’t want to die she couldn’t imagine leaving her daddy and sister alone - not when they’d already lost so much. from that day forward she’d do everything she could to survive, she’d never let her emotions break her down as much as they had that day no matter how much it hurt; she had to keep on living.
the fall of the farm came with several causes, rick and shane shooting off a gun in the woods and the fact that it was just time for them to move on. being unsure if her sister or brother were dead was something that terrified her till they got onto the road.
verse one. beth toughens up while on the farm instead of falling into a depression in the beginning she asks someone from the group to teach her how to shoot a gun. she wants to know how to protect herself from the dead, how to keep herself safe from anything or anyone who might try to hurt her.
verse two. beth breaks up with jimmy right at the beginning of the breakout but he is stubborn and don’t listen to her. always calling her his girlfriend around everyone, and he is persistent. telling her daddy about it doesn’t help because he thinks this is some kind of cute teen relationship spat, so she turns to her sister for assistance in the matter hoping she’ll be able to ward jimmy off.
