AOBA:“The area where ozone is vented in to maintain
aseptic conditions isn't contaminated.”
MISATO:“So does that mean that its weakness is oxygen?”
UrsusArctos: Guess what, it's another Andromeda reference, since the Andromeda organism showed a distinct vulnerability to oxygen and a preference for carbon dioxide. Although the mystery behind how Andromeda functioned was never solved in either the book or movie versions, both featured discussions of how its growth was affected by the sort of radiation, acidity-alkalinity, and so on. No such luck here, although as an SF fan I love this little homage.
