you know what would be scary?...if steven decided to discard his gem in order to make new life.
a daughter or son, a pure gem and using all his power, his very life in exchange to create his child...a pure gem, a new pink diamond with the emotional maturity of both pink and steven.
imagine him giving up on life and see no other option but to die but not before leaving a legacy that will not have to suffer what he went through, a powerful being capable of overcoming any challenge in exchange of his life.
in order to make a "new" gem, he will become a host, a organic injector, this process will drain all of his lifespan and the life around the place permanently.
steven will be gone forever but the "new" bearer of the pink diamond gem will go on.
of course this isn't a mpreg wet dream but an actual possibility, steven may figure out a way to do the opposite of what his mother did to have him and permanently separate his gem from his body in exchange to create a new pure gem.
