Julian calls it ignorance. "If you'd just join Garak and me for lunch," he says, "you'd see that Cardassians aren't all alike. They're not all the enemy."
But Julian's got it wrong. Miles is elbow-deep in Cardassian tech every day, and there's no better window into minds. Cardassian engineering twists the most straightforward purpose, and when you think you've got it sussed, it twists again. It's bloody sneaky and there's no trusting it.
Miles makes sure he's busy Tuesday lunchtimes. He couldn't stand to see that Cardassian telling lies with a smirk on his ugly face. Or Julian smiling back.
