Defiant

Gul Dukat: [about his son] Today is his eleventh birthday. I'd promised to take him to the amusement center in Lakarian City. He always wanted to go. But I never had the time... I told him, 'This year will be different, Mekor. This year, I will make the time.'

Commander Sisko: I had the same experience with Jake. At that age, they never understand, do they? You just hope that one day later, they'll look back and say: 'Now I understand. Now I know why he did that.'

Gul Dukat: When my son looks back on this day, the only thing he'll remember is that a Federation officer on a Federation ship invaded his home, and kept his father away from him on his eleventh birthday. And he won't look back with understanding. He'll look back with hatred. And that's sad.
