If you don't want to know the circumstances surrounding Friday's entry in this slideshow, then don't read any further...
[spoiler]Friday's quote:
Ep #764 (1897) - Evan - 'When the moment comes-- the real moment-- everything MUST go smoothly and without error. You understand?'
From "Robservations 1/13/03 - #764-765 - Are Silver Bullets a Solution?"
Tim is licking his finger and reading the text. He has four pages left to go. Evan tells him he's done quite enough; he's very impressed with his work. He suggests they "try the card." Yes, says Tim vacantly. They sit at the table. This time, no mistakes, Tim, warns Evan, when the real time comes, all must go without error.
[/spoiler]
The Robservations references the quote well, though, again, not directly word for word - but at least this time it does include "must"...
And Evan actually says "try the cards," plural, not singular...
