The biggest loophole to this theory is that Tsar promised to come right back after the meeting. Unless he sent Dmitri to get Lawyer and he was putting on a show for the actual bad guys but them he 'lost' him and now his dad's blood hound is gonna find laywer. My other theory is Dmitri is sh** and Lawyer will use his dad to save Ceasar. I am not spoiling, just theorising, cause I love guessing where the author is going with their story...
