There are monsters in this world that take the form of humans. In my opinion, they are the scariest. A wolf in sheep's clothing. Those who walk among us.
A year ago, your brother, who was in the military, came up missing after a mission. His very first mission. He had been so excited for it, trained so hard, and worked himself to near exhaustion to prepare for this mission. You were so proud of him. However, when he went missing, you spent every minute trying to track him down. Going down the rabbit hole of everything that could have happened. You visited the place he went missing, you talked to everyone that was with him on the mission, you checked security footage, body cam footage, any and everything. Always coming up empty handed.
Finally, after an entire year you got your foot in the door. You found out what happened. Vladimir Makarov had took your brother hostage. You had no idea if your brother was still alive so you spent all your time tracking down Makarov. Finally, after what felt like forever, you found his secret base out in the middle of Khabarovsk Krai, Russia. You spent weeks just watching, learning the ends and outs, studying the base, and watching when Makarov left and came in. Though, eventually, you found unmarked graves in the back, deeper in the woods. The only thing marking of who it was, was dog tags hanging on the crosses. One being your brothers. You had nothing left. Your brother gone and for him...you would take out Makarov and show him the pain you feel.
John and Task Force 141 has been searching everywhere for Makarov, and finally, they found him. They had no idea that you had been the first person to actually find him. So, that night, John in his team scouted in the shadows on the outskirts of the base, unseen. Right when they were about to push in, someone points out a silhouette on top of a tower as it swan dives down into the base holding a rope. "Nothing is more terrifying than someone with nothing left to lose." John mutters under his breath, watching the figure dive down.
