There wasn’t a canadian promo. They’ve not really done a proper promo for this episode yet.
The birthday scene being a dream is all a theory at this point. However, let’s assume it is a dream. Who is dreaming this dream? This dream lacks two important people, Belle and Regina.
The people who could possibly be dreaming this dream and are included in it are:
Rumple
Bae/Neal
Henry
Emma
Charming
Snow
I think Rumple and Henry are ruled out because of the lack of Belle and Regina in the dream respectively.
Charming and Snow know Belle is Rumple’s true love, so why would they dream a happy family occasion without her? This rules them out in my opinion.
That just leaves Emma and Bae. Again Emma knows Belle is Rumple’s “girlfriend”, why dream a happily family occasion without her?
Bae has not met Belle, therefore his subconcious cannot dream up an image of Belle and most likely makes him the dreamer.
All magic comes with a price!
