Google was unhelpful in trying to find that.
Was thinking, the Arturiae who are summoned as another class due to differences in their Legend, like Assassin or Caster, would remember a rather different Fourth Holy Grail War, if they recall one at all. I've mentioned Assassin, already, but if Kiritsugu already had Caster, would Uryuu get Saber Gilles, or someone else, entirely? He really has the wrong personality to get Jack the Ripper, for example. Also, how would each change Kiritsugu's strategy for the War? Lancer Arturia would probably be treated pretty much the same, but Assassin and Caster don't really fit that mold.
