Of Hxs and parasites

David:

My memory of HP is getting ever more unreliable, but doesn't HBP 
imply  Tom bumped off his dad and grandparents at the *beginning* of 
the fifth year? And the simulacrum in COS, presumably frozen at the 
age 
of his last memory input to the diary, is a prefect.

Kneasy:

Dunno.
Can't recall either, only managed to plough through it one and a bit 
times.
But if so it's yet another reason for my not liking HBP much.
Ah! Let me recount the ways!

David:

 Or did he use another murder to turn the diary into a Horcrux?

Kneasy:

Is it 100% definite certain and indupitably for sure that it was a 
Hx? 
Cos if it was, why was it so different from the other known/putative 
Hxs?

Snow:

Ewww, I like it! Dumbledore has a certain way of casting a spell on 
the readers to trust everything `he' says as so. Dumbledore does 
however admit many times that he is running on assumption when 
speaking of the Horcruxes although the Memory!Horcrux incident with 
the Diary is not one that he directly admits to but could it be
an 
assumption? Is the Diary the only Horcrux with a memory or is it the 
only one with a memory of Tom? 

A half-truth from Dumbledore surly must be absurd!

It's one of those unknowns that we are dealing with, which is the 
Horcrux and its affects. Does a Horcrux creation hold a copy of the 
owner's self when it was created or more so the death it was created 
with? 

Does a Horcrux hold the same powers that the owner itself does and/or 
was the Diary the only Horcrux so far that exhibited a memory? 

We have seen a possible Horcrux (the locket) act on memories
is there 
a connection?

Also does the selective death in making a Horcrux cause the Horcrux 
to act in a specific manner if attacked? Would this give credence to 
Sirius accusation that his brother was not important enough to 
directly be killed by Voldemort? Voldemort aimed for specific, 
important individuals to make his Horcruxes didn't he? 

Something to think about for sure

Snow - realizing that this is far from the Kneasy chessboard but 
interesting all the same
thanks Kneasy and David
