Great writing.
At the beginning, The Man says "lessons are extra". But at the end he's like: "gets down to what it's all about... making the wrong move at the right time" which is a lesson. He has respect for Cinci.
If the Kid saw the cheat, surely the Man saw it too. And Man saw Kid stop it from happening, which was "the wrong move".
The relationship btwn names: Kid vs Man. Man knows Kid's a worthy successor. just ain't ready for him... yet.
