Corrected entry: At the end of the episode after delivering his complex greeting to the Jarada, Picard and Riker head for the Turbo lift. Just as they are about to enter, Picard opens his mouth really wide as if making a funny face to someone inside the turbolift or maybe quietly celebrating a 'successful take' given the bizarre nature of the greeting! Although it was filmed from the side it is quite easy to spot.
Corrected entry: When Picard leaves the holodeck after the holodeck character kisses him, the lipstick remains on his face. As we're told later in the episode, matter created on the holodeck cannot exist outside the holodeck. So once Picard left, the lipstick should have vanished since it came from a holodeck character. The "correction" that says simple matter can leave the holodeck is incorrect, since in another episode, they throw a book (which is simple matter) out of the holodeck and it dissolves.
