I finally realized why I do not believe ESE LUPIN...

I truly like the ESE Lupin theories, really, I do!

However, I cannot make it fit cannon nor characters...IMHO..

So if not Lupin, then who?

I'd argue that it would have to be Dobby...

It would make sense...

Dobby tries to save Harry yet fails miserably..(on purpose?)

Harry's initial response to Dobby is one of mistrust.

Harry gains Dobby's trust by setting him free..(there has to be a 
reason why there are such tight restrictions on houseelves)

In the end Dobby ends up in enduring the same fate with the "other 
house elves"...

Given how no clear explanation of the "house elf" plight is apparent 
in the text...I'm beginning to wonder if JBE(just being an elf) may 
have a more significant meaning than most of us realize.

I believe that if anyone will betray Harry in the final book....it 
will be Dobby, not Lupin.. 
Doddie,
(who seems to remember that Harry seldom shares his elf experience 
with Hermione who has done much research on elves, unlike Harry and 
the rest of us.)
