You know, I wonder if part of Blue's issue is some sort of code whereby a Fairy cannot become involved in the affairs of Mortals unless they are actually called on to interfere. Such as when Jiminy summoned her, or Bae. When August was electrocuted, we saw that Blue appeared when she was called.

By the fairy code, if she is not summoned, she is bound to not interfere in the affairs of Mortals.

This could also explain Tinkerbell's excommunication. It wasn't necessarily that she helped Regina (because, let's face it, when she first stepped in, Regina was a dead girl without Tink's interference), but because she interfered into the affairs of mortals without being summoned.
