Chuck Bartowski:  The mission 's over dad .
Steve Bartowski: It 's never over , all right ? There 's always another _ one _ and another . And ... the reason a spy has to have one of those is because every mission they go on could be their last . For every spy , there 's someone who cares about them . Someone who has to open that box , read that message , and mourn their loss . This is a bad business . And I do n't want my family any part of it !
