Agree. Although his attitude about pregnancy being stupid is pretty caustic, I suppose under the survivalist circumstances it makes more sense, which is the point. Also I missed that the narrator was a woman until I thought about the vowel ending. I was thinking "You killed my father. Prepare to die." I missed any hint of relationship characterization between the two characters, so viewed it merely as a humanitarian collaboration.
It's a pretty compelling mission, braving death on the calculation that there may be a cure and a place to get the research to. Pretty high-minded and altruistic. I'm a bit skeptical that such a mission would be undertaken by a character who is a "natural pessimist" (at times Francesca reminds me of an insurance actuary). Makes a bit more sense that Garrity works primarily on comics, where such conflicting traits seem to be the commonest method of character development.
Never judge anyone until you have biopsied their brain.
