Okay; two major loose ends; 1) Mitzi is/was Blaise's playmate/consort, so, unless there is a whole lot going on that we haven't been informed of; Pansy and Millie have just brought a viper into their home.
And 2) Obviously Blaise isn't gone, she/he/it whatever, has at least one horcrux; so, it's still alive. I do wonder though, why Eliza didn't take Blaise somewhere outside the house to have her snack?
Looking forward to the last chapter, and also good luck with your original fiction

Yep, Mitsy is the modern equivalent of a Trojan Horse - but will she stay loyal to her "Dark lady?"
Inquiring minds will find out in the next and last chapter.
Don't worry too much about Eliza, you don't get to be 500 years old by giving up just because the house is coming down on you.
