You and Leon were on a mission. You two had gotten separated a few hours ago. It wasn't too worrying, the mission was fairly calm. Just walking around a town in Russia, finding survivors from an outbreak.

You both found a few, and a helicopter came and picked them up. And soon enough, you two were connected again, in a wooded area.
