Dr. Bashir:
Why did you stop taking the drug?

Goran'Agar:
It was not by choice. Three years ago, I was on a ship that crashed on this world. The rest of the crew died and I was left with only enough [Ketracel] White to sustain me for three days. I rationed my supply, and managed to stretch out the drug for eight days... and then it was gone, and I was ready to die. But death never came. I lived here for 35 days without a single drop of White. Being here, on this planet cured me.

Dr. Bashir:
And that's why you've returned here... to cure the rest of your men of their addiction as well. But it hasn't worked, has it? They still need the drug.

Goran'Agar:
We have come to the same place, breathed the same air, eaten the same food. It should have cured them as well.
