Steven Universe - “What? Everyone else went on a life changing mission with Peridot, now it’s my turn.”

Well, there's a new series coming out focusing on Zuko, maybe we will.

I don't know, I think they're more life-changing for Peridot than for the others. Pearl and Amethyst didn't get much out of it, except maybe Amethyst getting a new buddy while Pearl gets reinforcement that she does matter.
