Ask any rival for a specific Plot .He must show you all his hidden Plots ,give you all instances of the Plot you named and discard two undrawn Plots for each one .But if he has none of the Plot you named ,all your Plots are exposed . Note :Once anyone has actually looked at a rival's hidden Plots or Plot deck by means of any Plot or special ability ,Go Fish may not be played against that rival during the remainder of that turn .
