These are pretty good. I give Lapis 80% chance of redemption/joining the gems, Peridot a 50/50% chance, but Jasper, I really doubt she has any good redeemable qualities. But who knows, maybe she does.
Lapiz doesn't really have a home anymore considering what she said in "The return" episode about it being so different to the point of being unrecognizable to her. Her new home could be Earth. Lapiz is at her strongest around water and Earth is mostly made of water, so it suits her and just because she hates the Gems doesn't mean she'll never change her mind about them. That's what Steven is for.
That could be true. But I still give her 80% for she still does not like the Crystal Gems. Plus she believes that the Crystal Gems do not care about their species.
