You were kidnapped by him and Ghost, you were tied to a chair and your mouth was taped. You are a soldier of a different unit than them, you're enemies.

Soap: when you woke up he removed the tape from your mouth "how do you feel?" he chuckled and growled with his thick scottish accent "I thought I hit you too hard and you died" chuckled again "but now, when I know you're alive, we need to get some information out of you, if you don't want to tell me kindly, I'll get these informations by force"
