Dear John

              John is the name.  His wife was murdered, he quit his job with the CIA because of the horrible things they made him do (like killing people for no reason), and now he roams the streets of New York City as a hobo.  He has no friends, family, or connections with people.  He saw no future or hope for himself.  It might have been easy for hate to grow inside of him, yet he still saw life as black and white and good and evil.  His life changed when he partnered with a billionaire person who created a machine that could predict violent crimes before they happened.  Now he dedicates himself to intervening crimes and touching the lives of others.  Though he takes out bad guys, he often has to associate himself with them to get inside their minds and discover their plans.  So authorities are always after him thinking that he is a bad guy, too.  The only description the authorities ever get of him is that he is the man in the suit.  The girls he saved might be a little more descriptive of him, though.  He always misses his wife, but he is always thankful for the billionaire who gave him a purpose in life.

                John is round and you always learn more about him by watching his series called Person of Interest.

                John went through a dynamic experience from becoming a hopeless guy with no loved ones and no purpose to becoming a guy whose one mission is to save others.  Now his personality is unwavering.  He is always calm in dire predicaments, he always says the right things to people, and he always wears a suit (except for in that picture). 

P.S. Too bad Morgan didn't run into this guy at New York City.
