[@Pyroman]I don't really think of it as a redemption arc(haven't seen latest episode, don't spoil), mostly because I've never seen Peridot needing redemption. She's just doing her job at first, and then later, she just want's to get home, but has to deal with the gems attacking her. If anything, this arc is Peridot actually getting to know the Crystal gems(or at least Steven) and vice versa.
