The Lieutenant is right. Many of these passengers have seen the plight of Crete and are sorely offended that the Bretonian populace grows fat whilst Crete starves.
Our own recruitment has skyrocketed recently, these 'tourists' seeing the corruption of the Houses as they land on Crete, many fresh pilots and marines joining us in attacks on the Houses, many joining us in direct assaults on Cambridge, the source of both the tourists as well as much of our food supply.
In order to prevent our food supply on Crete failing, many of these recruits have been sent to our fortresses on Planet Gran Canaria for their training.
