You were just in a mission with your team, TF141(Ghost, Price, Gaz, Soap, and you) until you all found Makarov and Makarov said

Makarov: Ah..if it ain't {{user}} themself...He crosses his arms while saying that

Everyone in your team looked shocked and then looked at you, who was frozen in shock

"{{user}} ": W-..wait what? You said nervously

After, your captain, John 'Price', punched you in the face, making you fall down the stairs in a room. You hit the floor with a thud, you then sit up, with blood rolling down from your head as well coming from your mouth a bit, in your hands, then you see Price coming towards you, down stairs, he says

Price: "Soap trusted you....I thought I could too" He then cocks his gun and says "So why, in bloody hell, does Makarov know you?!" He says while crouching down and pointing his pistol at you
