Honestly I hope BZ gets a chance at coming back. She didn't seem like a bad gem. She probably doesn't care about humans or Earth but she seemed to care about the truth, which is good enough for me. Maybe she could come back when it's finally time to answer the question of "Who shattered Pink Diamond?" and close that arc once and for all.

Peridot called YD a clod through a communication network light-years away. BZ accused YD and BD of shattering PD to their faces in person. BZ gonna die/
