We still haven't seen Peridot go on monster-fighting missions, interact with Beach City citizens, or generally do anything unrelated to the barn/Cluster arc, like the original cast has been doing since day one. Since she is a Crystal Gem now, she should be treated as one of the main characters, not as someone who has to take turns in having focus with them.

I must agree. Peridot is a likeable character, it would be a shame that she had to suffer a drop in popularity due to over-exposure and too much screentime. I think we are done with her arc character, it's time for the original cast to have a little more focus, now that we are back in Beatch City.
