It sounds like it refers to this meaning (from Merriam-Webster online):
Main Entry: 7 con
Function: noun

something (as a ruse) used deceptively to gain another's confidence; also : a confidence game.

He started doing his "act," his line. His way of presenting himself to gain another's confidence, trust, etc.
