My master was not - as a rule - particularly interested in the fabulous locales and exotic cities we journeyed through; Athens was the exception that proved the rule.
When they try to board the ferry to either Alexandria or Cairo after having met Sophos he will interrupt them and invite Passepartout to drinks at a nearby taverna. If Passepartout goes along, Sophos will ask him to investigate his olive shipping operation in Antalya as he suspects that the man in charge over there is involved in illegal activity. Depending on dialog choices Sophos will either offer him money or a ride in his private airship from Beirut to Manama as a reward. In both cases he will divert the ferry from Alexandria/Cairo to Antalya.
