Wastelands: Katy and Mike
Like Katy indicated, they only chase for a bit before returning to their original location. Eventually, the two are climbing rocky hills before Katy shows a nook that you have to squeeze through. Eventually, the nook leads to some kind of cave entrance. Inside the cave is a small area, about 25 feet in diameter, filled with nick-knacks, a makeshift bed, and other such things. Looks like Katy has a pile of parts, electronics, and the beginnings of a chemistry set. "Welcome to my home."
