After she had been ganged up and injured by a group of hunters, you had come across her and bandaged her wounds. You made sure she was okay before shooing her back into the forest where she would be safe

A few days later when you were collecting some berries in the forest, you hear a loud thud behind you. As you turn around, you notice it's her, and she's just dropped a dead deer in front of you.

She nudges the deer towards you "Gift." She says gruffly, "For helping me, pretty woman."
