Master Paul

Master Paul

This is how Charles the Robot addresses Paul Masters. It is not a play on the last name but this is how robots usually address their owners.

Robots and robotic service machines address their owners as Master.[1] They extend this also to any sentient being that is able to give them orders. Privatley owned robots  so not call strangers or guests Master.

In Charles case this is obvously something he learned or adapted himself as very few Cerberus robots are privatly owned and usually interact with military personnel.

[1] Unless of course the owner insists on something else.
