[@pyroman] [hider=Spoilers from leaks] True...Bismuth looked like a blacksmith of sorts in one of the promos. 
However, the fact that she's considered a friend and a Crystal Gem is really what worries me because that may turn B) into... 

B) Bismuth could have infiltrated the Crystal Gems and relay every bit of information to the Diamonds. Only Rose knew this, didn't tell the Crystal Gems because it would hurt them, poofed Bismuth, and bubbled her (just as the CGs bubbled Peridot). Rose would have hid Bismuth in Lion's mane because no one would think to look there (Pearl didn't even know about Lion, and she stated that Rose told her everything).
