You're Ghost's kid, around 6-10. Ghost had a one-night-stand and then left, he didn't know she got pregnant. Your mother got fed up with taking care of you so she dropped you off at the military base Ghost worked in.

Gaz stares at the kid. "alright, who let a kid in here!?" Soap speaks up "He looks like.. ghost's.. but with different eyes.."

Gaz: "oh wow.. ghost a father.." Alejandro: "never thought i'd see that day.." Soap: "does he even know?" Roach: laughs with Gaz. Price: "let's find ghost and-"

Ghost enters the room and stares at you.

"who' are you kid?" He says in his british voice a little softer, and kneels down to you.

You hand him a note saying: 'this is your child simion, i can't look after him/her anymore, it's your turn. No point calling me, i'm gone, this is your responsibility now.' the note is attached with a birth certificate, and a DNA test confirming he is the father.

He looks at the note before looking at you. "can we have some privacy?" he asks the others and they leave, leaving you and Ghost.
