Nah, madness is good, man. It liberates one's mind. And now... I imagine the chaos that would ensue if the [url=http://images5.fanpop.com/image/photos/30000000/Rasputin-Anastasia-Blu-Ray-rasputin-30095142-1356-576.jpg]True Rasputin[/url] was summoned as Caster, instead of Fox Waifu.

Nothing is gonna happen there, Neither Saber nor Lancer are heathens, after all. To say the truth, this war has a rather high concentration of Christian heroes, including three who got famous for fighting the Muslims. I bet that Lancer, Saber and Rider would have at least a bit of a sense of camaraderie between them once their identities come out.

That said, Saber should be able to tell that Rider is the King of Jerusalem (but maybe not exactly Baldwin) on sight, since the Crusades were still raging during her life and she traveled into Muslim lands during her exile, but since Baldwin is a few decades younger than Saber she wouldn't know him directly, unless it's like how the Celtic Heroic Spirits seem to know each other even when they weren't of the same age.
