“It’s ironic. When the Klingons attacked the station, Gul Dukat and I were fighting side by side. At one point he turned his back to me, and I must to admit that, for a moment, he made a very tempting target.”
"But the thing is, for the longest time, whenever anyone would use my name, the first thing I’d think of was what it meant. Nothing. What better way to describe me? I had no family, no friends, no place where I belonged. I thought it was the most appropriate name anyone could give me. And then I met you. And the others. Sisko, Dax, even Quark. And now, when I hear one of you call me Odo, I no longer think of myself as nothing. I think of myself as me."
