Trust is not easily gained with so many layers of ingrained distrust to remove. Yet those of the Thirteenth Order have made tremendous progress. Whether Spiridopoulos will ever totally trust his Cardassian comrades remains to be seen. I think he wants
to, but I don't know if the questions will ever fully disappear.
I like the reminders that the Cardassians are more "alien" than the Federation aliens as the Starfleeters cope with strange foods, shipboard customs and environmental systems. Small details, but they add much to the stress and the story-line.
And to echo BrotherBenny - what the heck just happened?
