One of the very first characters I designed for the project some 3 or more years ago, even before Arkham Origins.
Vassili missed a shot once. It was rather an important shot, with a lot resting on it, and it disappointed a lot of quite important people. Not the target, who was delighted, as were all the people who'd voted for them. But the point was, Vassili was no longer welcome to work for his own government, so now he contracts out on the open market. But then who could shoot their own sister?
