As it seems we differ, on the “abnormality” of Yuuki’s thirst.
The recent lack of tameness is incomparable to the fits we've already seen Yuuki capable of when she's excessively hungry. Its not like this:
Physically, all she's done is grab her neck a few times and mutter about good smells. Her lack of control currently is her emotional tension and inability to think clearly and how she is easily distracted (course she's always been easily distracted, it just matters more now).
The scan that you are providing IMO reinforces my stance that her jump on Zero’s neck isn’t justified by her hunger, due to emotional tension alone, cuz even when she had these terrible fits, which almost drove her to “madness” she still refused to use her fangs and quench her thirst. As you said those fits are incomparable (or should be) with her current situation. She was like a wild animal, hence and her basic instinct should drive her to the first available neck … but no. However now she isn’t satisfied with the blood from Zero’s wrist but she jumps on his throat like a”rabid cat” lol.
Also when she was unconscious and wounded she managed to resist.
Now even if Zero was the love of her life, and nothing holding her back, still under the conditions their relationship had been for the last year, plus her character, should be enough to restrain her from jumping to his throat. For me Yuuki is OOC there.
And blood tablets not making much difference is not new, at least to Zero
Swallowing numerous pills and minutes later at the mention of Kaname's name:
Zero falters heavily. As a level D, Zero isn't the best example, but the idea of the ineffectiveness of blood tablets isn't new and Yuuki has had as bad fits even as a pureblood.
As you already said Zero isn’t the befitting example … but still he managed to hold himself using tabs for a year. Yuuki has only a few days (a month?) that she had fed with the best fresh blood and in large quantity haha.
Also notice this … she started to have fits a few days ago but she was very composed. Her emotional tension more or less was the same … I mean her situation didn’t worsen so drastically to justify a drastically change to her thirst degree. My interpretation is that her thirst fits in frequency and in intensity terms, has increased after she took the tabs.
The night before, Yuuki has a bit of a hunger pang and pops a tablet, then two more.
The defuser in the scene where Yuki "jumps" Yori, was not the blood tablet, but Yori laughing at her, Yuki makes a face (she was mostly making a point) and pops a tablet and then all is good for a while. It seems to me that Yuuki was making a poor emulation of Zero:
I’m not saying that she was serious when she jumped to Yori … of course it was a joke (well I hope it was … you never know hahaha). However the meaning behind that scene is that she was agitated/lured from Yori’s delicious blood! To the extent that she had freaked out with her own self … There is the emphatic point … she was so hungry that she shocked from her own thoughts! And she had taken 3-4 tabs just hours before.
When things are calm and normal, they pop a tablets into water and drink and thats fine. Maybe as someone else pointed out, Yuuki just isn't popping enough because of her stress. Kaname under stress, has a whole handful, yes, he's not accepting the human offering, but he still requires that much to sate his thirst.
Just another factor to consider.
- Emotional stress and conflicts (multiple)
- Inexperience with tablets (not used to their lack)
- Not enough tablets
- Only had pure blood previously*
So if satisfaction is different from sating the hunger, exactly how is it different because vampires still hunger after being satisfied (or have we never actually seen a satisfied vampire?)...but they also hunger after they have been sated. You always get hungry again...
I will add another reason … Zero’s blood is obviously wanted … despite the nature of her feelings the fact is that she loves him … and as Yori’s example reminds us, the blood of a beloved one is more appealing. So after she smelt his blood I would find it more logical or possible not to handle to resist and drink from his wrist … as I said above the OOC is the sudden jump.
Also … why is Zero offering his blood in a very intensive way? From what he says, probably he also found Yuuki’s state out of control … remember when she was wounded he suggested to take tabs … now why he isn’t suggesting her the same or if you like advise her to increase her dose????
Again … even if Yuuki didn’t take the right dose shouldn’t be just a little bit less hungry?
All the factors that you’re pointing out are true and especially the emotional stress I also had pointed out as a source for her thirst … but still for me are enough to justify her hunger not the jump … and here after a circle we reach to the same point … we differ on the “abnormal” intensity of her thirst, which led her to jump.
The satisfaction and the satiety are two different things … the lack of satisfaction doesn’t drive a vampire to jump on the first available neck obviously … if so as I said the NC wouldn’t have managed to restrain themselves from attacking to the DC for example, cuz as it stated the tablets didn’t satisfy them. However when they smelt fresh blood were getting agitate, but still they managed to hold on.
Contrarily if a vampire is not sated meaning its hungry, eventually will not restrain from a prey. The tablets aren’t providing satisfaction but the essential nutriment hence and tame their hunger.
From what I understand … a vampire under the tabs is like a human on diet haha … the dietary-food it’s not satisfactory but inhibits the starvation.
