I'm not saying that you or i should like him! Anna need to like him!
Look at him, he's an old ugly-freak!
Just so you understand, its another story about blackmail! Henk will most likely blackmail Anna with her husband's company, Marvin will also probably dig up some dirt on her and blackmail her with it, and the new old guy will do the same!
As for me, it would be better to make him a "handsome" (for Anna) man of 50-55 years old. He would apologize to Anna and trick her into believing that he didn't "mean to do anything wrong", and at this moment Anna is in a disagreement with David, and she is very vulnerable, so Mr Strenstronger can "comfort" her, he would be able to manipulate her "correctly". And it was much better than another blackmail story!
