This is also the end of Mon Mothma as a Mother, a wife, a friend. It is her catharsis and it's meant to be long and painful to watch her emotional realization of whats to come.
I think I got that after the 13th cut back to her dancing. Not sure if all 17 were necessary (yes, that may be an exaggeration).
I'm all for slow burn. But at some point the story moves so slowly it seems more like ashes where you're not even sure if there's still an active ember or not. I hope the pace pics up a bit from eps 4 onward. Otherwise my social-media-ruined attention span might not be able to cope.
