Inside the Blue Parrot, Ilsa has rejoined her husband and the two are speaking with Ferrari, who says he's unable to help Victor get out of Casablanca. However, he might be able to arrange an exit visa for Ilsa only.

Ferrari, his offer having been rejected, informs the two that the letters of transit were not found on Ugarte when he was arrested. They were probably entrusted to Rick.
Is that the plot thickening, or just some of that famous Moroccan humidity?
