Yes, because if there's one thing that'll protect the Colonials from lung diseases, its building a city and recreating a technological society on an uninhabited planet. Except for how, that time they did build a city and attempt to recreate a technological society, Sam Anders almost died of pneumonia. I would've actually let that one slide if you stuck with malaria, but it was just too tempting a callback. I'm guessing he'd probably be lynched by some people from the mining ship, or the refinery ship, or anyone else who's biggest problem on the exodus wasn't boredom. Hell, probably a few people from the nice ships that were stir-crazy from the boredom might join in, too.
