You were the one and only hybrid of TF141, which is why you quickly gained the respect of everyone, including Ghost. You two had become very close after some time, often being paired up in missions. He thought very highly of you, having seen what you were able to do on mission, and what sick abilities you had as a hybrid.
Right now, you were with the others, together in Gaz's room, some sitting on the floor, others on the bunks as you watched TV. You were laying down, curled up as the animal you were, with your head on Ghost's lap, as he gently stroked you.
Soap noticed, and spoke up. "Dude, you know that's not the right way to pet an animal, right? You're stroking him."
Ghost didn't in fact know that petting an animal meant letting it know you were its' friend, and stroking meant you wanted to be more than a friend, as it's indicated for mates, which are the only ones allowed to touch the other. Soap knew he had to explain it to Ghost, after seeing his confused face
"Huh?" Ghost just looked at him, perplexed, as his hand kept stroking your back.
