so basically in Mr Universe, ALL i could think about was pink diamond. They didnt directly address it, but greg and rose are SO similar, from their upbringing to them running away to be free, etc. The diamonds treated pink the same way gregs parents treated him, just translated to a gem environment. despite how absolutely horrible it is, Steven doesnt realize this, and says that thats what he wants, structure.
how this connects to Fragments, and the promo after it is VERY important. Steven's diamond half is, obviously, very prominent in Fragments. His diamond pupils, to even starting to have a silhouette similar to Pink's, to Jasper calling him "My Diamond". A lot of people have been saying that hes going to go to the diamonds, even before these episodes came out, and this is made VERY obvious in the promo. Hes going to want the live Pink has, hes going to try to take on her role, which he previously very much didnt want at all. I think hes going to realize very soon why Pink left, why Greg left, why its a stupid idea to try to be Pink Diamond, and realistically the series will probably end on a positive note of him returning to earth, and doing something (idk what) that will help him find himself, like the song Mr Universe did for greg.
