Yeah, that is a good point! So you would have BB-8 sitting outside Rey’s home, then you would pan up to the stars, maybe some kind of dissolve or something to the opening shot with the moon, star destroyer passes over, transports fly out and BB-8 sees them?

EDIT: What if Rey could somehow see the Star Destroyer looming over the moon while she was sitting outside at night? It could be like how in the early cuts of ANH, Luke entered the story when he saw the battle from space, before the audience really knew his place in the story. Though I guess that was cut for a reason.
