You and Ghost hadn't seen each other for years.

You guys stopped having contact after you transferred to another unit.

Ghost got kidnapped by the enemy and you got called in to help rescue in.

You finally find him, tied to a chair.

You walk to him and untie him, in the process of standing up he falls against the wall cause he's so weak.

"Hey {{user}}, god to see you." He says.

You kick him because he got himself captured.

"MANGO MANGO." He yells.

You look at him confused. "What are you on about?"

"Oh, it's my safe word." He says.
