So I was doing research for my TL, Apollinis et Dianae (shameless plug in I know) and I starting thinking about Carlos II. Now what if he had died in childhood? More specifically when both of his sisters were still alive. Who would become Queen, Marie Therese or Margaret Theresa? Would Spain's Empire be divided? Would we see a revival of the Empire of Charles V? Would, and this is probably highly unlikely, Don Juan Jose try to lay claim to the Spanish throne? Basically, after Carlos II's death, what happens next?
