Also it’s for the finale so probably trying to keep as much under wraps as they can convince the network to let them (I know they get overruled for a lot of the promos etc throughout the season and don’t have much control over it, but they might have a bit more for finales).
I know last year there were only 3 sneaks and the last one showed up 3 hours before it aired on the east coast. (That last one was pretty spoilery too as it showed Emma waking up Maleficent and having a sword in her hand), so as much as I want to see the sneaks cause I’m chomping at the bit for this episode, it also wouldn’t surprise me if we don’t get much or if it’s really stretched out, even though a lot of stuff has already been spoiled. I hope we get SOMETHING we don’t expect so we can still be surprised.
