One question Agy.. why do the other gems dislike the others(Garnett,Amenthyst,Pearl)
we don't know yet, the only hints they have giving so far is it looked very much like they knew they were keeping lazris as a prisoner. and that she wanted to go home but the others didn't.
also when the other gem came form there home world, the gems were freaking out, garent destroyed the warp station, in such a way that it appers she was the one who destroyed it in the first place.
also the way they hide form the gem makes me think things.
my guess is rose, pearl, ammy, and garnet ran away form the home world for some reason. and that they don't want the other gems to know pearl ammy and garnet are alive for some reason.
it might have to do with steven being rose's son. it might be against there law to have a child as rose had to give up her life to give birth to steven. so maybe they are protecting steven ^_^
