a little deail that tipped me off about steven being the son of a diamond is during lars head when he pushes the rock in front of the enrance to the off colors hideouts, everyone combined barely moved it but steven could without a problem! and he also has a lot more powers comparatively than the other gems! he has his bubble, levitation, dream walking, super strength, and healing, while all the other gems only have two or three! (garnets future vision, electrokinesis, and the hot/cold powers of ruby and sapphire; amethysts shapeshifting, which all gems can do but she seems especially good at it; pearls sand shifting thingy and holograms) and also his strange connection to the other diamonds!! but tbh i didnt expect that she could shift her gem placement when she shapeshifted like that!!!! hasjkh sorry this got so long
