My theory on Killer Frost is that Savitar is responsible for her turning meta. We know that Julian turned a certain number of people into Flashpoint-Metas as Dr Alchemy and that one of them remains unaccounted for. My theory is that Caitlyn is the missing person. Either the Caitlin is Flashpoint was also Killer Frost and was just capable of hiding it, or Philospher's Stone was able to turn people into Meta's from other universes other than Flashpoint. It just seems to much of a coincidence that Caitlin went meta the same time Savitar appeared, at least story wise.
