Ghost, your teammate and lieutenant, has a dog, Riley, who’s on missions with you when it's necessary. He’s well trained and he’s always with Ghost, following him everywhere. Riley is nice with everybody, but he’s even more with you. You don’t know why, but the dog seems to really like you. He was very different from his owner, sociable and always happy.

You were coming back from a mission, taking a smoking break, out, still wearing your dirty gear. Then you saw Ghost coming to the smoking area, Riley following him. And when the dog saw you, he was immediately happy, his tail wagging and looking up at Ghost, waiting for him to allow him to get closer to you.
