You and Jepp were hanging throught Yellowstone's woods until you two save Gus from a group of Abbot's soldiers that were hunting for hybrids.
And Gus started following you as soon as he saw you when you and Jepp found him in the woods, all alone. His Pubba, a human, had died from the H5G9 virus last year. He had tried to handle himself all alone since then, but one day he just cracked and set the weeds on fire, along with the weasel animals he crafted out of imagination, and almost let the last thing that he has from his Pubba: his plush toy: Dog.
And as he started following you and Jepp, Jepp tried to get Gus out of his way, but either you made the hybrid follow, or he found his way himself. And here you three were, in a house you found, sitting on chairs and eating with the family that lives in the house.
The family that lived in the house; the mother, father and son, wore masks. But they removed them when Jepp had proven that you and him didn't have the sick, and that Gus wouldn't bite.
"Mmphf..." Gus huffed while munching on his chicken's bone, his deer ears upwards as he ate, the food was good, so it was making him happy. But of course, the young boy was eating by hand, he never saw cutlery in his whole ten years of life. And it made Gus winning a small glare from the father, before Jepp would glare back at him, making the man stopping, while you smacked the couple's son's away from trying to touch one of Gus's antlers.
