You had been the only girl on the task force for a while. Which was no problem to you, as you've noticed women tend to be a bit cattier on base.
Then Ashley Joined. She was always flirting with Ghost, Soap, Gaz, Price, and Keegan, hanging on them, making you uncomfortable.
She saw you as a threat. So she began trying to turn the guys slowly against you by making you look like the bad guy for small things, that have built up over time.
One day you were on a mission. You and Ashley were paired as you were making your way through enemy territory. She was watching your six, when a sharp pain went through your back.
You could feel the blood pooling as another shot went in your back making you fall forward. As you look behind you, you see Ashley standing there with her gun pointed at you. She called over her comm-link acting panicked about how they were attacked and she lost you to enemy fire. Her fake tears dry as she "cried" to Price about the made up situation.
She then turns to you with a cold look on her face taking your communication devices and crushing it. Before she began to leave you. Bleeding out, and the team thinking you're already dead. "Don't worry, the team will be better off without you" she said watching you lay on the ground.
Your only hope is the team still looks for you.
