(Dr. Keller and Todd are in a lab on Daedalus. Dr. Keller is working on a computer while Todd is wandering around looking at the equipment in the room.)
Dr. Keller: We've run close to a hundred simulations based on full medical scans of the Wraith we've had in...captivity.
(Dr. Keller gulps nervously, but Todd seems to take no notice.)
Dr. Keller: They've all been successful.
Todd: We both know very well that computer simulations and live trials are very different.
Dr. Keller: I don't think we're doing this cavalierly. I stand by the data. It will work.
Todd: Uh-huh. Perhaps it will.
Dr. Keller: The question is. Do you want it to?
(Todd turns and looks at her, humming thoughtfully.)
Todd: I do see the benefits, even if we only use the therapy on some of my troops, say those whose lives, thanks to this war, are expected to be short. Why waste perfectly good resources on them, yes? But it will be very difficult for me to ask those around me to give themselves over for the good of the human race.
Dr. Keller: But it's for your benefit too. If you don't have to rely on human feeding, the war would be over.
Todd: Perhaps. (looks away) But then what would we do? Who would we be?
