Garak: 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 admit that for a moment he made a very tempting target.
Odo: You'd shoot a man in the back?
Garak: Well, it's the safest way, isn't it? But then I thought, well, no, I can't fight all these Klingons by myself. So I let him live.
Odo: And now you regret it?
Garak: Ah, my dear Constable, before this day is over, everyone on this station is going to regret it.
