Wait, when did we decide that Blavat knew about the Universal donor and recipient? Wouldn't that have taken away all the urgency about getting blood for RCiel--or am I getting Polaris and Sirius confused again...I know I have done that from time to time.
Who knows how the blood typing really works?
Ch124 has Blavat explain to the "Sirius" renal failure patient that he's never received any blood from "Sirius" donors. It's all been from the "leftovers", meaning Vega and Polaris, since Canopus has always also been too scarce.
This means that Blavat must realize Sirius can accept (whole) blood from any of the donors, or at least he realizes Vega and Polaris blood are acceptable. Otherwise, this guy would already have died... horribly... from rejection of the transfused blood. But, if Blavat knows this, why is real Ciel not using whatever blood he can get?
Similarly, Ada must have somehow figured out (or been informed) that Canopus can accept from Canopus and Vega. Because Baldo seems to be getting blood from Lau (Canopus) and Conny (Vega). Others are also donating, and I have to assume they are also either Canopus (rare) or Vega (common).
In the Kuroverse, Sirius is AB, the universal recipient for whole blood... and Vega is O, the universal whole blood donor.
It gets flipped around for plasma donations in the real world, and we also have to consider Rh-factor, but this whole ABO blood typing thing seems to have been simplified for the story. In reality, there are even people who fall outside the ABO system.
What I want to know is whether the lords of the stars are aware of this fact... and whether Undertaker knows. Because -- and I've blogged about it many times -- this whole time real Ciel has been able to accept absolutely all of the blood donations (keeping the ABO system simple, no Rh-factor). The one that should be "starving" is Vega... but only if they use the blood the way the system truly works.
If real Ciel and the other lords know, then there might be some sort of elitism going on here, particularly with real Ciel. Like... he refuses to accept any other blood type because he thinks it's inherently not good enough for him. Or maybe Undertaker is under that false impression. Or Druitt, if he's involved, since he does have that medical license that's otherwise gathering dust.
I wonder what Sieglinde has now figured out regarding the ABO -- or Polaris-Canopus-Vega -- blood typing system. Will there later be a scene where real Ciel complains of not enough blood, and someone pipes up to say he could have transfused any of it? This whole time. And he's just in shock about that.
It's entirely possible that Blavat doesn't care about these renal patients so much that he gave Sirius renal failure patients Vega and Polaris blood, not knowing they would be okay. Basically, Blavat might have stumbled upon the truth... and never reported his findings to Undertaker or real Ciel. 🤔
