Do you know that Alex was in the ballroom scene?
In one scene when you see paul holding a plate, you would see someone with long hair on the left of Paul. You could only see the hair, not the actual person. At first I thought it was Zora, but from the way they were standing, Zora was standing across from Paul.
So, the person with long hair got to be Alex. She should be in the final ballroom scene since she has been touting the "fairy tale" storyline ever since the first episode.
How ironic that Alex's name was the first in the credits, with so little face time? :
I watched the show twice (both East & West Coast broadcasts) to confirm my observation that Alex was in the ballroom scene.
