THIS IS A MAJOR SPOILER FOR THOSE WHO DIDN'T SEE THE ENDING TO BLOOD+!!!! AND ME, BEING BE, WILL USE THE ICONS, BUT THOSE WHO SAW THE ENDING, YOU WILL KNOW WHOSE WHO!!!!

I just have a quick Q, how come didn't died when did. I mean, just because blood wasn't effective as doesn't mean die! Both should of died! blood and blood inside should of killed her. But no, the anime must end with sleep! Can someone please explain to me how didn't died with both of the blood inside her and did died with both blood inside her. And I want someone explaintion, not the anime's explaintion!

PS Should this be under Life or something else?
