True, but in the end it's just semantics
1. How does it not fit in with canon?
2. You can't just ignore an option you don't like. And neither can Bioware. I agree that Jadus will probably never reappear, but only because it seems unlikely that we're getting class story expansions any time in the foreseeable future, and I don't think I would be the only one who would be highly annoyed if Bioware started ripping characters from class storylines and putting them into the general game and thus effectively saying, "Well if you didn't pick x/y/z choice in your storyline, too bad, your story is now nullified."
