"Our lead on little miss ended the moment it was confirmed that she's alive and was brought to New York." Viktor's consigliere said, as the old man stood aside, deep in thoughts as he stared at the file of his missing daughter, Aubrey Petrov.
He voiced out everything Sergie was saying while trying to put his brain to good use, trying to think of where exactly Christopher would have kept his daughter to the point that she wasn't seen in the system, since after it was figured out from the last friend of his that died in Igor's hands at him questioning him about Aubrey.
It was not just any speculation from him, Christopher kidnapped his daughter, just to ensure that he hurt them. An act that he wouldn't have done to him, regardless of their ugly history. He's a father, and so was Christopher too, but then their grandparents weren't so keen on favoring parenthood, to stop hurting each other to the extent that Christopher went to hurt them.
