The Black Fairy is probably not going to be banished in this episode. Tinker Bell was banished, and presumably ended up in Neverland, when Regina had just recently married Leopold (when Snow White was a little girl, roughly 10 years? before the curse). This flashback takes place when Belle is in Rumple's castle, which is the same time Regina is the Evil Queen and Snow is a bandit, probably only a couple years at most before the curse. Tinker Bell likely would have no knowledge of the Black Fairy's banishment if it happened so many years after she left.

I wouldn't be surprised if the Black Fairy is in the present day plot. I still don't think she'll stick around long, though. Unless it is a set-up for a future plot.
