HBP, GG, half-blood?

No: HPFGUIDX 104542

A while back there was a discussion going about the identity of the HBP
(last week around digest 4835 or so). I just finished OotP for the third
time this evening and noticed a couple of interesting points (that may have
already been pointed out). First, during the fight at the MoM Bellatrix
calls Harry a half-blood. Second, when Dumbledore is discussing the prophecy
with Harry, he also states that Voldemort (upon hearing the partial
prophecy) decides to kill Harry, choosing him because he is a half-blooded
wizard like himself (as opposed to Neville who is a full-blooded wizard).

Two points I take from that. First, in every other instance I can remember
half-bloods refer to wizards with one wizard parent, and one muggle parent.
But there is no doubt that Harry's parents are both wizards. Now Lily (if I
am remembering my information correctly) is the child of muggle parents,
thus being a "mud-blood" (pardon the expression). But does her muggle
parentage qualify Harry as a half-blood, even though she was definitely a
wizard?

Second point - Some of the discussion last week centered around GG as the
HBP. I still think that this is true. In light of what I have just read, I
also think that there will be some sort of revealing that Harry is a direct
descendant of GG, thus passing on the title to Harry.

Cheers,
