"Jeez," Beth says, sounding impressed. "You've done everything." It seems like maybe some of these things are impossible, but she's seen impossible. She's seen her mother rise from the dead and try to kill her, she'd felt her dead fingers curling in her hair and smelled her rotten breath as she'd tried to sink her teeth into Beth's cheek.

Beth cares about people, she likes being around them, and she wants to take care of them when they need it.
