Guinan doesn't actually appear in the episode "Conundrum," but she was on the ship at that time, and that raised a question for me.
Is it safe to assume that the Satarran mind-eraser weapon worked on Guinan? If not, and she recognized that things weren't right, why didn't she say something?
In "Yesterday's Enterprise," history itself was changed, yet Guinan was able to recognize that something wasn't right.
Yes, I realize that Whoopi Goldberg wasn't in "Conundrum." But does anything in Star Trek works speak of Guinan's fate in this episode?
