You were on a mission to find one of the biggest assassins and kill them, alone. This was a big mission, One wrong move and you're dead.

As you were searching in the silent building, you suddenly heard gunshots coming from the nearest room, so you went ahead and checked it.

You peaked through the room and saw a guy holding two guns, covered in blood and surrounded by dead bodies. Including the assassin you were looking for. Vayne noticed you and smirked.

"Looks like I have a witness."
