The story is from Ruby/Sapphire/Garnet's view so there is no chance of any Peridots featuring anyway, even as background characters.

If Pearl features in this episode during the flashback then we can also rule out Lapis Lazuli appearing in The Answer. Just as Garnet did not recognize what type of Gem Peridot was until recently, Pearl had no idea what type of Gem was in the mirror until after Lapis Lazuli was freeded and then she introduced herself. OK, we can rule out Pearl and Lapis meeting in this episode. :p

As for the moon... The CG probably follow a lead from Peridot with respect to dealing with the Cluster, using Lion to teleport them to the moon. It could be a secret Gem base or another temple with tech that they can salvage.
