Yup, frankly, I don't think every loose end will be tied up since the main goal right now is probably closer to just getting back home, so the swan dealing with this issue feels like the story is a lot closer to its conclusion than most of us would like. There's still kind of the issue of Surma... kind of. We haven't seen the other half of the crew in a while, plus the walk-in refrigerator situation, but that's hardly the biggest problem of the ones the mages have been dealing with.
I hope the ending at least has a bit more of a focus on exploring everyone's personal lives and their futures. Adventure 1 ended in a way that would've been pretty unsatisfying in terms of character development if we didn't know we'd have the beginning of Adventure 2 to look forward to, but now that we know Adventure 3 won't be a thing, I really want to see a little bit more of their regular lives when this one ends.
But maybe it's too soon to think about that!
