I am aware that they filmed two scenes. The one scene we already know is the same scene that Jennifer filmed. They just filmed parts of it again, parts with Snow and Charming in them, that i am sure will be cut and pasted together. There is a second scene that we know of. I think this is the scene that is the conversation with Henry or Ella or both, probably about true love’s kiss or about some magical way to help them. Snow and Charming may linger in the back for a few scenes, but i think that there will only be two scenes of significance. There may be only two scenes period.
One is the big scene with everyone and then there is a second scene. The only part of this information that is actually a real quote is that they have “a critical role to play in the finale”. All i am saying, is that i think a conversation is most likely what they are talking about, though it could be some random magical help. There is nothing critical in this show though because no one ever dies that you don’t know is going to die. That has been true for many many years. The only deaths that were remotely surprising storywise were Graham and Neal. The rest were expected and Henry is not going to die.
