I'd be interested in the other contradictions you've noticed. Because I'm the sole writer without much editorial input, I'm sure continuity suffers at times.
I can find the instance where Nadya mentions not having much savings, but I'm not sure where she states she's well-off. Having a good position at a university doesn't immediately translate in a lot of savings (maybe she spends a lot). Do you have examples where the key moments are too forced?
As for the main goal, I assume you mean the search that kicks off in Episode 1? Without a clue where to look, it takes a while for them to get all the clues they need, they're a bunch of fresh navy cadets, after all.
