As far as I know I’m the first person to have pointed this out: When The Prisoner tells #2 “You won’t get it,” there are (at least) two distinct meanings for “Get it.”
The first, you’ll have no purchase, no ownership of, you will not know where or what “It” is.
The second, you’ll hear it BUT not be able to understand “It.”
After I posted that, @ me blog, someone pointed-out to me that #2 tells The Prisoner in response to his question
"Who is #1?"
“You are [#1], #6.”
