Watching the Wrath of Khan on the AMC, I’m not sure what to make of Spock’s comment;
When remarking that both ships shields will not work in the nebula, spock says to mr saavik,
“Sauce for the goose, Mr. Saavik. The odds will be even.”
What does sause for the goose mean? Icing on the cake? But that doesnt make sense, because there is no “cake” in this situation: Is it somehow meaning to “Even the odds?”
=PK
“What’s sauce for the goose (female goose) is sauce for the gander (male goose).” i.e. (in context): We can’t see him, but he can’t see us.
In this particular case, he meant that the odds were now not favouring either side.
“It’s bad that our barely working systems will not work at all in that nebula, but his systems won’t work either, thus negating any disadvantage to us, Mr Saavic.”
Bad for us + bad for them = good for us.
