Well, found amnesiac wife and I just used logic to search nearby caves, kinda on path between CC through caves if one tried to get to SGS.
Place where wife is (I assume she is wife, dunno for sure yet) is hanging rat bar, which was very much in that kind of direction. Figured I missed something between but could not find what it was. Seems we each had one half of the thing..
Anyway, cave is like, two east from hanging rat, and one north, or so. If coming from opposite direction, you go West from the abandoned Bunker where the Mutagen canisters are one or two zones. New cave, with body and little else but a keycard with the missing husbands name. Might be more if I'd found it properly perhaps. And no, there is no dorm room to look into with the keycard, only use could find was turning into vera with a 'I know nothing else or even where the merchants are' ending for me on the issue.
