Just start the game with the Chaplin chits piled up in the middle space. If an event says move one right, move it one space right, and vice versa if it says left.
All characters starts in the Person-of-Interest-Box, but Reynolds move to the 18B Status at beginning of the Invasion Segment. Take a look at his description.
The Chaplin status is only used, if Chaplin is covered and the event "Eagle has landed" is placed or at the Final Attack.
In the other cases the Chaplin chart is used and the status is ignored.
