Seems that is the big mystery today? Yuno was able to kill the 11th, and she most certainly didn't wait for him to come out of that vault first...what exactly happened? Seems she really doesn't want Yuki to know about it, and if you can't share your heart with the man you used to have drugged and tied up for weeks then there is something really wrong. A delicious little mystery, and it seems like we're very close to the end. It's been a great ride, hasn't it?
