I want JKR to write 2 encyclopedias, I admit--the regular one
she's promised, and an all-Snape one. And this is one of
the topics I want JKR to eventually address--why did we 
learn Snape could do complex healing spells by voice alone?
What was the point of that scene with Harry, Draco,
and Snape in HBP? Sure, it helped the reader to 
connect Snape to Sectumsempra, but otherwise, why did
Snape need to display such dramatic healing powers?
In the rest of the book, his healing powers can
be connected with his skill in potions (Katie's
necklace, for example)--but not this one. So what
gives with this glimpse of Snape, master of 
healing skills?

I also want to know what happened that made Snape 
so very, very bitter about showing affection/emotion. While
Snape/Lilly might explain his distaste for student love in
general, it doesn't explain how he acts as if any display of 
emotion is something to be mocked, and mocked heavily.
Before, when we theorized he got the name "Snivellus" from
being emotional/crying easily, that would have explained
this--he was horrified by his youthful emotions and how they
set him up to be a social victim. But now that we know
he didn't get the name for any such reason, there's no 
specific reason given from the leap between Early Snape
(definitely an introvert, but able to express his emotions--see
the whole sitting by Gryffindor Tower incident) and 
Bitter Snape ("fools who wear their hearts on their sleeves," 
mocking Tonks' patronus as "weak," etc.)
