I've been looking at the hiding rules and what I keep seeing is when hiding you have to have either cover or concealment. You can have Cover or Concealment from some opponents and not others. In this case the creature moved into a position where Ning didn't have either. IF the creature had flew down and breathed in any other direction then right in Ning's face, I could see how the mephit might not have noticed him before Ning's action. It would be like you hiding around a corner and someone might not noticing you while walking past the corner.
I did realize that the other creature who breathed onto the group didn't spot Ning. So the creature should have a 50% miss chance because Ning is basically invisible.
Everyone feel free to weigh in on your perspective.
