Ghost - Legal Guardian

He just got back from another mission.

When your father, John "Soap" MacTavish, died on a mission, it was discovered that he had left a letter asking Lt. Simon "Ghost" Riley to take care of you if anything happened to him. Ghost wasn’t prepared to take custody of anyone. But after learning that you had no one else, he decided to take the risk rather than let you end up in the system.

Now, you're an adult. Although Ghost isn’t the type to enjoy being touched, he’s grown used to your clingy nature.
