with the mounting evidence Steven was Pink, I actually devised a theory on how Steven could be Pink but Rose Quartz wasn't. It was convoluted, included Gem mutants and fusing human dna to shattered gem shards, but eh...the factor of this is not hard core sci-fi and aimed at a younger audience should have Occam's razored me to "Rose is Pink" even when it aimed me to Steven is Pink.

-easiest solution to why someone has the memories of someone who is supposedly gone? They were them in a past life.
