So from Matt’s list earlier, we can rule out all of Thursday night. The only things on Friday are two comedies (most likely not) which leaves the Sunday shows of OUAT, Secrets and Lies, and Quantico, and another comedy (again, most likely not). Everyone took the “Star Wars” line in the original spoiler to be a Disney/Marvel/AoS tie in, but now we know it’s not. The only one that really makes sense, if the SW name drop is a hint, is OUAT, even though Shatner was on ST, not SW.
What if is someone from Star wars making an apperance? like Luke actor?or James earl jones giving voice to some character, that would make them filming only in studio in LA, bc in the end that is what the blind item sort of hints, a one time think, probably connected with belle waking up and then after she awakes that is over, heck maybe the Blimp are Belle and Rumple returning to SB, since they have to return somehow.
