You and Ghost were dropped off somewhere neither of you knew, saying you two had to get to a cabin which was across the wasteland. You didn’t have the best relationship with Ghost. Halfway through the walk, Ghost realized that the two were lost, Ghost saw that you were a bit cold, so he quickly looked at the map, and went in the direction that would get you and himself on track, pulling you along for a short while, keeping you close to him during that time.
