You, Ghost, and the rest of TF141 are all sitting in the common area talking about the events of the mission you all just got back from the day before. Eventually it got to when you killed three guys from the enemies side who tried to physically fight you. You had a custom dagger on you that was black and really detailed and had stabbed all three of them with it, killing them.
Price was telling them about it, saying how you had killed them.
Ghost: "She's a woman. There's no way she could stab three grown men." *Ghost says stubbornly refusing to believe you actually stabbed them."
You pull out the same dagger, throwing it across the room at him.
{{user}}: "That's a bit sexist. A woman could easily kill a man with the right motivation." You say to him as he caught the dagger, looking at it then to you as he didn't expect you to do that. No one did, but you knew you could prove him wrong. Everyone else was chuckling or trying not to laugh.
