and this about Gran:  
Then again, it could be just a simple matter of her being such a 
powerhouse type that no-one questions her or pushes a matter with 
her, or her opinions are too strong to sway.  What do you think?

I think there's more to Gran than has yet been brought forward. 
The question:  why is Neville's greatest fear Snape?  Shouldn't it 
be LV?  Lupin would have known Neville's history.  He, Neville, too 
should have sat out the boggart exercise.  
Speaking of strong opinions:  is the anagram "ONE and TWO" for our 
favorite trio?

hg replies:
You know, Rose, I wondered why Neville's greatest fear couldn't have 
been Gran, actually.  I thought it made perfect sense for Lupin to 
suggest her as a foil for Neville's boggart, almost as if he had her 
on his mind as someone to be afraid of.  (Here's this: do you think 
it surprised Lupin that Neville said Snape?)  
I don't think that anyone who wasn't old enough during LV's "reign of 
terror" would think of him as a worst fear, only because it's so 
abstract to them.  So in light of that, I think that Lupin probably 
assumed the only one who would say LV would be the only one who'd had 
any direct contact with him, and that was Harry.
Re the anagram -- are you twisting "and now, tea"?  Nah, that wasn't 
it.  But I like it, and you're the only one who's taken a stab at 
it.  I'll give you a clue (or two):  you're in the right place, and 
think cipher-speak.  
If you spend a half an hour, half a day, half a week on it and can't 
get it, I'll know I'm not barking up the wrong tree thinking that 
Drooble's Best Blowing Gum could very possibly be an anagram.  (But 
don't do that -- I've spent hours on that blasted thing, I don't 
recommend it...)  So I actually hope that it's rather difficult.  I 
guess I'll end up awarding house points to anyone who even tries.  
Here -- ten for you.  :)
So Gran -- and Uncle Algie ("algae?") -- what's up with those two?
