Elliott Blake:
The third card after a wavy line is always false. How many times have we been through this?

Dr. Paula Hall:
I'm sorry, Elliott. I - I tried.

Elliott Blake:
'Try' to understand; there's a precision to all this, and it starts with the premise that you will lose your institute unless you please the military and Mr. Harrow. Do you think you pleased them, Paula?

Dr. Paula Hall:
No, not yet.

Elliott Blake:
Not yet, because you gave them 74% accuracy when you and I agreed to set a level of 86%.

Dr. Paula Hall:
Right! We'll rehearse it... [picks up ESP cards] again. The first answer after the square is always true, unless there's an intervening circle, and the second answer after a wavy line is always false, unless that wavy line itself is false... or is it true? [throws cards at Elliott] God, I don't know anymore! So much for our scientific study of extrasensory perception.
