Actually come to think of it, it’s probably just that they haven’t added the CG yet.
Agreed, I reckon when we actually see the ep, there’ll be a cricket and two fairies hovering between Belle and Granny.
Wouldn’t make sense to send the fairies off somewhere else initially IMO, because then they’d have to show a whole other location in order to show where they are. But if they stick them in this shot, they can have Blue tell the others that she and Tink have to go gather up the rest of the fairies and survey the lay of the land to check on everyone/thing, and off they’ll fly.
