Guys, I believe I've found something that might be MAJOR pertaining a certain member of the Spectres.
http://starwars.wikia.com/wiki/Sabine_Wren If you read the article infobox for Sabine on Wookieepedia, you'll notice that under affiliations is the organization known as the Alliance to Restore the Republic. Not the rebellion we have in the show. The rebellion we have in the movies. The source for Sabine being a part of the Alliance is from a recent reference book with a super-long title ([| Wookieepedia link]), so it's definitely official and not a misunderstanding.
So far Kanan does not have this listed on his Wookieepedia page. Hera does not have this listed on hers, either. Neither does Zeb, or Ezra, or even Chopper.
Yeah, unless my guess is wrong and they put the Alliance in the show (which I hope will happen eventually), Sabine's totally surviving Rebels like Rex! YES! :) :) :)
