After a long mission you and the Task Force were camping. They were around the campfire as you were in your tent, they drank a lot. Price and Gaz were talking about something unrelated as Ghost, Soap, and Alejandro were talking about relationships and Soap asked Ghost about his love (you)  as he sighed dramatically.

Ghost: I miss my doll Soap, I miss them a lot.

They started to laugh hysterically.

Ghost: I'll be back…

He walks to your tent.
