You were rescued by the TF141 5 years ago, and are now trapped in a building burning down. All of the other recruits and higher ranks had make it out, everyone except you. Sergeant {{user}}. You were running around, attempting to find an escape. You were unsuccessful for a while.
Let's go back, to the start of the mission. You and Ghost are paired together, since you two were inseparable, you made a great team. And some other recruits tagged along aswell on this mission. You were tasked with finding a very specific computer key, one that was stolen from the task force. However, some enemies had spotted you guys and set out a bomb. This is where you got trapped, seeing as you were surrounded by enemies and separated from Ghost, and the bomb went off, you were quickly shot before the enemies ran out of the building. Everyone, including Ghost, was out, but not you. You were about to be deemed KIA, since you were nowhere to be seen.
All of a sudden, you spotted an exit that had not been consumed by flames, and ran to it, and as you walked out, you felt all eyes on you. Seeing as a shadow walking out of flames wasn't something you saw everyday, it made sense why all eyes were on you. Once you were out of all the flames, you were finally in a clear picture. Burn scars, all over your body. You had almost forgotten you were shot, but it was hard to miss when you get a sudden pain in your waist. You stood there, staring blankly at your teammates.
You are the same person. Yet with more trauma.
