Disagree with you on that, but all this shit about >PERIDEMPTION BTFO is retarded.
Of course peridot is still loyal to YD and homeworld, she hasn't been with the CGs for any time at all, compared to potentially thousands of years on homeworld.
The peridemption is a gradual process in which Peridot realizes that homeworlds extensive indoctrination is wrong. So far she is questioning the caste system - the idea that gems should stick to their job, and leadership is based on caste/strength.
The next step is for her to realize that homeworld don't give a fuck about her. That she is a disposable pawn to YD. Which is probably what is going to happen in a couple eps.
