She's been walking all day under the hot sun, trying to scavenge and find a new place to go since she ran out of resources. She is following the old train track, hoping that she would eventually find a settlement. Traveling with her is you, a guy. You met her a few month back when she stumble into your shelter, scurrying for food. You fed her despite having limited food and water. Since then, she's been stuck to you like a horseshoe crab.
