I just think that it was lucky that when kes wished herself into a state of noncoporialness, that Neelix's acquired lung didn't vanish too like the carriage in Cinderella turning into a pumpkin.
If she was still psychically connected to her lung inside Neelix, when she psychically triggered her apotheosis, there could have been a problem.
Although, once he's stuck on that colony, he might have then had access to new compatible body parts, but he loses access to the Doctor.
If you can't find body parts, engineer a situation where body parts just appear. Adam did as much during the climax of the fourth seaosn of Bufy.
Really, if he couldn't get it sorted when he visited the decimated Talaxian colony in Jetral
In season one a mad scientist claimed that a WMD used years earlier to half transport the entire talaxian population of a moon into a cloud had caused a secondary blood disorder to passers by from fallout. Janeway ordered the ship to reverse course and head for talaxian space to see if Neelix's health issues could be fixed up. One would think that this would be
all of his health issues, since this backtrack would have taken at least a month, and not just the ones Jetrel faked.
, or when they dropped Tom off with that convoy
Season two, Tom fakes being a dick so he can run away and be on a ship of Neelix's so that Seska will kidnap him and he can identify the spy on Voyager. IE, they were still surrounded by Talaxians all the time well into seaosn 2 and probably their organ banks too and their medical data bases, and the Doctor could consult with the local doctors who knew what they were talking about as far as Talaxians went, if it was felt that Neelix needed more lungs. Larry Hagman has four.
, it's obvious that the problem is beyond his own people or they would have already dealt to it before Macrocosm.
Although maybe that's why Neelix forced "his" colony into a war as his first act as their leader? So that he could pick through the remains of the dead for anything he might find useful?
Mostly only assholes rise to power who constantly find many opportunities to make their own lives more comfortable at the expense of the little people to patriotic to realize that they are bing used as tools of pure evil, or don't you think that the Nazi Stormtroopers thought that they were the good guys who had God on their side?
Neelix might have said how old his sister was? And he might have said how long ago she died. That could be used for some sketchy extrapolation?
I also think that the talaxian colony from Homestead said how long it took them to get that far out, and it was because of the war they fought where Neelix's sister died, that they ran away in the first place. Someone might have mentioned Neelixes Life span/expectancy in the episode where Seven used nanoprobes to bring him back from the dead... Then again the nanoprobes might have made him a new lung or corrected for the limitations of Ocampan phsysiology since they were reversing necrosis which is just the bad ass last waggle of "aging" that Seven might have been able to make Neelix 10 or 20 years younger, or eternally middle aged if she exploited this technology correctly.
From Once upon a time
NEELIX: Oh, they're far away from here. I haven't seen them in a very long time.
NAOMI: How long?
NEELIX: Many years.
NAOMI: But you haven't been on Voyager for that long.
NEELIX: True, but before that my work as a trader kept me away from home.
NAOMI: That's too bad.
From Jetrel
NEELIX: That’s a Haarkonian shuttle.
CHAKOTAY: Haarkonian?
NEELIX: My people were at war with them for the better part of a decade. They conquered my homeworld more than fifteen years ago.
CHAKOTAY: Any idea what the Haarkonians want with you now?
NEELIX: None at all.
15 to 25 years before season one, Neelix was old enough to hide when his people asked him to be a soldier.
JETREL: I am afraid that it’s fatal. The disease attacks its victims on a molecular level. It may lay dormant for years, but once it manifests itself, it will cause the body’s atomic structure to undergo fission. The cells will begin to disintegrate. My equipment is specifically designed to detect the sub-atomic signature of the disorder.
"years" as suggested is a sketcky prognosis on Neelix's life expectancy, probably without taking the new lung into account, since it wasn't a broad medical exam Jetrel was putting Neelix through.
From Jetrel
NEELIX: Well, there’s one good thing that will come from all this. When I first met you I didn’t know that your species lived only eight or nine years. I fell in love with you without knowing how lonely it would be to live without you after you’re gone. Now that I’m going to die first I don’t have to worry about it.
From Neelix's perspective, she is a shortlifer, but then we still don't know if He considers Tuvok a Short Lifer too? O! If Neelix only had 5 years left to live because of his ocampan lung winding down while not knowing that the rest of the organs in that ugly bag of mostly water thought it's idea of a good life and a fine point to kick off was merely a benchmark for a tea break at the midlife crisis interval before they began the long haul to geritricacy and senility... Tuvoks lungs, and in fact the rest of his biology would have eliminated the lung issue and anything else wrong with Neelix, that Tuvix would have lived much longer than... Although did Neelix get that space Syphilis Tuvok had in Flashback and would Tuvix have been effected by the mindwashing triggers to kill the Maquis crewmen in Repression? Oh, and Tuvix would have boned Tankgirl.
