So, at first I was like...
Oh it must be mostly the Rumbelle bits of the fandom that don’t like The Blue Fairy because ya know fairies and Rumple don’t get along.
But then I realized…NOPE!
Basically everyone thinks Blue is shady and hell and that’s GREAT!
The moment I started not trusting the blue fairy was when she turned jiminy into a cricket because we all know what evil fairy dust does.
