i think 3 theories:

1) She/he is a crystal gem on the cluster. The crystal gems separate a shard for the cluster gemstone, but only a shard, and the other shards of she/he too, so steven use hes healing powers and she/he regenerates as a normal gem. And helps they to find periot or something like that.

2)the same story, but she/he dont regenerates as a normal gem, regenerates as a corrputed gem, i think a worm (because sardonyx is  a type of microcrystalline quartz, specifically onyx, and the Pokemon Onix is a giant worm/snake) and at the last (or the 4th episode of stevenbomb) she/he regenerates as a normal gem

3)Is another gem for the homeworld. Searching for Jasper and Peridot (and maybe lapis) and she/he find the crystal gems, and recognizes all of them, and like jasper, she/he thinks steven is rose (but this time is cuz his gem). she's more powerfull than jasper, and captures steven, leaving the earth and the crystal gems, in the earth, are trying to bring him back.
