Keegan Connor Tracy as the Blue Fairy/Mother Superior
I'm still not sure how I feel about the Blue Fairy, so far she's just kinda been popping in, f*cking things up for everybody and then buggering off! She seems like nothing more than a plot device and I just want more for her. I've read some theories that she fell in love with a mortal man and, to keep him from growing old and dying while she helplessly looked on, she granted him eternal life and power and he became the original Dark One. I'm so, so, so hoping this becomes canon because it adds so much depth to her character and give some kind of reasoning to her actions/meddling.
thanks to @blue-herring for the picture edit!!
