Phew... complicted but didn't take as long as you think! Scene from their fic:
Star: I bet whoever it was is hiding up there *motioning toward cliffs*
*All three glance up the cliffs*
Garnet: There's no way we can get up there... *blabbers about how dangerous it is... Sham edges away, unnoticed*
Star: Well there's no other way to find out. I bet Sha- ... Where's Sham? *both look around them until Garnet finally looks up at Sham, who's happily looking down and hasn't broken a sweat*
Garnet: Who's that even possible?
Star: *mumbles* When isn't something possible for him. Just shut up and let's follow him up there.
